Executive Summary and Key Findings Nordhaus finds that the optimal policy, given the current state of knowledge and ignoring uncertainty, is to do very little in the short term (a $6/ton tax in 2005) and only marginally more in the long term. While his mild long-term policy suggestion helps to inform the basis of his short term recommendations, Nordhaus only intends to propose a short-term strategy and emphasizes that policies should change as we learn more. Recognizing wide-ranging uncertainties and the possibility of calamity, Nordhaus investigates optimal policy choices over a reasonable distribution of possible states of the world. He shows that while the median optimal carbon tax is on the order of $6/ton in 2005, the mean optimal carbon tax is somewhat larger, at $18/ton in 2005. His conclusions are viewed with skepticism by some critics, who believe some or all of the following: he overstates control costs, he understates control benefits, and his choice of a positive pure rate of time preference is indefensible. Others find his results and methodology more robust. Introduction In a 1994 book1, Nordhaus calculates an optimal policy response to the problem of climate change. A distinguishing feature of this work is that it aims to uncover a truly optimal policy - that is, one that maximizes net benefit as opposed to one that merely minimizes the cost of achieving an ad hoc CO2 concentration target. Basic Results Ignoring uncertainty and with a best guess of costs and benefits (based on a wide purview of existing studies) Nordhaus finds that the optimal policy is to do close to nothing. With the optimal policy, carbon taxes rise from $6 per ton in 2005 to $20 per ton (1989 dollars) in 2100. Global average temperature under this policy increases 3.2°C - only 0.2°C less than in the baseline case. On net, the world economy under this scenario enjoys a small net benefit relative to the baseline case. See Table 1. Restricting emissions of greenhouse gases to 1990 levels, on the other hand, inflicts relatively large net costs. Carbon taxes rise to $400/ton in 2100, and the increase in global average temperature is limited to only 2.4°C - a full degree less than in the baseline. 090522AD.WPD Page 2 Given that the optimal policy is much closer to doing nothing than to restricting to 1990 levels, it appears that literally doing nothing in the short term is superior to current proposals oriented on 1990 emissions levels. Table 12 Global Net Benefit3 Carbon Tax ($/ton) NPV Annualized NPV as % of PV 2005 2055 2105 ($billions) ($billions) of baseline output Optimal Policy 271 11 0.04 6 15 21 (no uncertainty) Restrict to 1990 - 7,069 - 283 - 0.98 50 230 400 levels Stabilize at 1.5°C - 40,980 - 1,639 - 5.94 200 700 800 increase It is worth emphasizing that Nordhaus's result is not simply a matter of delaying controls. While the typical cost-minimization exercise also shows that carbon emissions should be allowed to follow a near-baseline path at first, Nordhaus's result goes further: he finds that relatively little should be done even over the long term. In his optimal scenario, carbon concentrations are allowed to grow without apparent bound. Incorporating uncertainty, Nordhaus's results change though the basic message of modest short-term measures does not. Nordhaus examines how the optimal policy changes when key parameter values vary from his best guess and finds that the mean optimal policy calls for higher carbon taxes than he finds for the best-guess case. The mean optimal policy calls for a carbon tax of $18/ton in 2005 and $53/ton in 2045. The "mean" result differs from the "best guess" result because the distribution of outcomes is skewed so that favorable climate change scenarios are similar to the best-guess case and occur with high probability while extremely unfavorable scenarios occur with low probability. Nordhaus finds that only 2% of possible scenarios the least favorable would call for a carbon tax in 1995 of over $100/ton. Basis for Results Nordhaus's results derive from three key assumptions: that the costs of reducing carbon emissions are relatively high; that the benefits of carbon control (in the form of averted damages) are relatively low; and that the social rate of discount is greater than zero. 090522AD.WPD Page 3 Critics have attacked Nordhaus on all three points, and it is worth examining each point in greater detail. 1. Costs The cost of reducing carbon emissions is determined by the responsiveness of the economy to a given level of carbon-control effort. For example, if a $10 carbon fee elicits a large response in terms of lower carbon emissions, the cost of carbon control will be low. Conversely, if a $10 carbon fee elicits a small response, program cost will be high. The impact on the economy of a carbon-control program in Nordhaus's model is determined by two key assumptions - one concerning the "static" response, given current technologies and carbon use, the other concerning the "dynamic" response, reflecting induced changes in carbon use and advances in technology. Nordhaus bases his assumption about static responses on existing empirical studies. His assumptions here are not particularly contentious. Nordhaus attempts to capture dynamic responses by assuming that technology will improve at about the same rate in the future as it has done in the past. Importantly, the trend rate of improvement is not allowed to vary depending on the price of carbon permits or the level of a carbon tax. Critics find fault with this approach, since his model thus assumes that carbon taxes will in no way accelerate the development of non-carbon technologies - in stark contrast to the "technologist" view. Nordhaus notes that his results are sensitive to assumptions about technology, but he does not document the extent of that sensitivity in isolation from other uncertainties. 2. Benefits The benefits of carbon control are determined by the magnitude of damages averted -- that is, damages that would have occurred in the absence of a control program. Nordhaus calculates that these damages would be relatively modest. For example, he estimates that a 3°C temperature increase results in only a 1.3 percent loss of output per year. Some critics feel that damages averted will be greater than Nordhaus assumes. They note that SO2 and particulate emissions will be reduced, biodiversity will be better maintained, and negative health effects will be avoided. In a survey of experts, Nordhaus finds that the median cost prediction for a 3°C rise in temperature is 1.9 percent of output annually 40% higher than his own. The mean prediction is much higher, at 3.6 percent. 3. The social rate of discount 090522AD.WPD Page 4 Given that costs are borne up front and benefits accrue mainly in the distant future, assumptions about the social rate of discount are crucial. Nordhaus assumes that the social rate of discount is 3 percent per year; this rate is sufficiently large as to significantly reduce the present value of the distant and already modest benefits. Many critics (mainly non-economists) feel that a social rate of discount greater than zero is indefensible on ethical grounds. However, mainstream economists strongly endorse the approach to discounting which Nordhaus uses and find it difficult to understand very low rates of time preference in the context of observed behavior. Nordhaus re-evaluates the optimal policy when the pure rate of time preference is only 1 percent and finds that the optimal carbon tax in this case is considerably greater (see Table 2). Table 2 Optimal Carbon Tax ($/ton) Rate of Time Preference 1995 2045 2095 3% 5.3 13.7 21.0 1% 23.6 52.6 77.5 Conclusion Nordhaus's analysis implies that little should be done either in the short term or in the long term. His results hinge on assumptions about technology improvements, appropriate discount rates, and the size of potential damages. Critics feel that Nordhaus may be: overestimating mitigation costs because he ignores the possible influence of higher energy prices in spurring the development of new technology; and underestimating damages from climate change. While both would tend to cause Nordhaus to be too lax in his policy recommendations, it is not clear that such criticisms can be sustained far enough to overturn Nordhaus's basic point that strict action is inappropriate in the short term. The discount rate issue, while crucial, is difficult to settle. 9/18/97 Outputs Modelers Target Timetable Trading Permit Revenue Burden BAU Paper Tons AEEI Ramp-up Time Path PDV (5%; GDP in 2010 ID Scenario Model Allocation Recycling Sharing Emissions or Corre- 2000-2050) (deviation Path sponding Foregone from BAU) Assumptio Reductions Consumption n SGM1 BAU SGM, Battelle n/a n/a n/a n/a n/a n/a IAT n/a 1.0 n/a -->2050, $121,650 billion $9,185 billion -->2100 (BAU (BAU GDP) MAGICC (climate) consumption) -10% of SGM, Battelle -10% 1990 stabilize in Annex I auction lump-sum no LDC IAT PT 1.0 no -->2050, $485 billion $9,155 billion SGM9 1990 in MAGICC emissions 2010 part. -->2100 (-$30 billion) (climate) 2010 level -10% of SGM, Battelle -10% 1990 stabilize in domestic auction Tump-sum no LDC IAT PT 1.0 no -->2050, $980 billion $9,149 billion SGM8 part. -->2100 (-$36 billion) 1990 in MAGICC emissions 2010 only (climate) 2010 level SGM10 -10% of SGM, Battelle -10% 1990 stabilize in worldwide auction lump-sum no LDC IAT PT 1.0 no -->2050, $50 billion $9,171 billion 1990 in MAGICC emissions 2010 part. -->2100 (-$14 billion) (climate) 2010 level SGM36 1990 in SGM, Battelle 1990 stabilize in Annex I auction lump-sum no LDC IAT PT 1.0 yes -->2050, $195 billion $9,179 billion 2020 MAGICC emissions 2020 part. -->2100 (-$6 billion) level (climate) SGM39 1990 in SGM, Battelle 1990 stabilize in Annex I auction Tump-sum no LDC IAT PT 1.0 in 2005 -->2050, $230 billion $9,172 billion 2010 MAGICC emissions 2010 part. -->2100 (-$13 billion) level (climate) SGM3 1990 in SGM, Battelle 1990 stabilize in Annex I auction lump-sum no LDC IAT PT 1.0 no -->2050, $225 billion $9,172 billion (-$13 billion) 2010 MAGICC emissions 2010 part. -->2100 (climate) level SGM18 1990 in SGM, Battelle 1990 stabilize in Annex I auction lump-sum LDC IAT PT 1.0 in 2005 -->2050, $255 billion $9,172 billion 2010 MAGICC emissions 2010 stabilizes -->2100 (-$13 billion) level at 2030 in (climate) 2030 SGM, Battelle 1990 stabilize in Annex I auction lump-sum LDC IAT PT 1.0 in 2005 -->2050, $260 billion $9,172 billion SGM21 1990 in 2010 MAGICC emissions 2010 BAU to -->2100 (-$13 billion) level 2030, (climate) equal per capita in 2050 SGM17 1990 in 1990 stabilize in domestic auction lump-sum LDC IAT PT 1.0 in 2005 -->2050, $740 billion $9,164 billion SGM, Battelle 2010 MAGICC emissions 2010 stabilizes -->2100 (-$21 billion) only level at 2030 in (climate) 2030 no LDC IAT PT 1.0 no -->2050, $665 billion $9, 165 billion SGM2 1990 in SGM, Battelle 1990 stabilize in domestic auction Tump-sum 2010 MAGICC emissions 2010 only part. -->2100 (-$20 billion) level (climate) Battelle 1990 stabilize in domestic auction Tump-sum no LDC IAT PT 1.0 in 2005 -->2050, $740 bilion $9,164 billion SGM38 1990 in SGM, 2010 MAGICC emissions part. -->2100 (-$21 billion) 2010 only level (climate) PT 1.0 in 2005 -->2050, $740 billion $9,164 billion SGM20 1990 in SGM, Battelle 1990 stabilize in domestic auction lump-sum LDC IAT 2010 MAGICC emissions 2010 only BAU to -->2100 (-$21 billion) level 2030, (climate) equal per capita in 2050 SGM40 1990 in SGM, Battelle 1990 stabilize in worldwide auction lump-sum no LDC IAT PT T.0 in 2005 -->2050, $5 billion $9,180 billion 2010 part. -->2100 (-$5 billion) MAGICC emissions 2010 level (climate) 9/18/97 ID Scenario Model Modelers Target Timetable Trading Permit Revenue Burden BAU Paper Tons AEEI Ramp-up Time Path PDV (5%;

Appendy L B TOMAN_IA.WPI TOMAN_IA.WPD Page 1 2. Cost-benefit analysis in "Integrated Assessment" models Integrated Assessment (IA) analyses try to bring together assessments of the physical, ecological, economic, and social impacts of climate change with assessments of policies for responding to climate change and their socioeconomic consequences. Generally speaking, the models can be described schematically as linking economic decisions in the energy (and agriculture) sectors that give rise to GHG emissions (and changes in carbbon sequestration), models of atmospheric composition, climatic change, and changes in oceans, and models that describe the potential impacts of climate change on health, natural resources, coantal areas, and other factors of socioeconomic interest. Different components of various IA frameworks are represented in differing degrees of detail and sophistication. A few models contain the capacity to be used for a benefit-cost analysis, in which it is possible to evaluate changes in the long-term path of GHG emissions that maximizes the net benefits of GHG control (these benefits are the avoided damages of climate change less the costs of control). A larger * number of IA models can evaluate the benefits and costs of specified policies but are unable to indicate what emissions reductions maximize net benefits. IA frameworks are inherently more "top-down" in their characterization of economic decisionmaking, though some models contain a fair amount of energy sector detail. A very striking feature of IA models is that they tend to indicate the desirability - - from the perspective of maximizing net benefits over time of emissions continuing to rise well into the next century, if not beyond. (For a recent comparison of IA model results, see Manne 1996. [JEFF: Do you want cites of individual models too?]) By 2010, the models indicate only small deviations downward from a business as usual (BAU) path (see also IPCC 1996b, Chapter 10). In some cases the emissions do stabilize toward the middle of the next century, but in other cases they continue rising (though more slowly than with business as usual) even beyond 2100. These emissions paths clearly imply increases in atmospheric concentrations of GHGs well beyond the kinds of targets that have been considered in current policy debates (e.g., 550 ppm). One important consequence is that the models indicate costs of near-term emissions stabilization well in excess of the avoided damage costs. AS nepal in Ex, A number of criticisms have been levelled at these IA results. These criticisms include: Failure to consider the possibility of unlikely but catastrophic events that could result from climate change (e.g., catastrophic sea level rise from melting of the Antarctic ice sheet, runaway global warming from frozen methane releases, or relocation of the Gulf Stream - see IPCC 1996a, Chapter ). Failure to give adequate consideration to the scale of potential damages, even in the absence of catastrophe. Cline (1992), for example, argues that damages are much higher than is incorporated in most IA models (see also IPCC 1996a, Chapter 6 for various estimates). One specific concern that has been raised is that the IA models do not account adequately for the costs of a less stable climatic and ecological systems in the face of GHG accumulations. TOMAN_IA.WPD Page 2 Failure to consider the adverse consequences of less aggressive abatement policies for future generations - in the context of IA models themselves, the criticism is that discounting of future generations' well-being is excessive. Cline (1992) also raises this concern, as does Howarth (199_). Failure to consider how uncertainty about all these effects affects the "optimal" decision (Pizer 1997). Failure to consider how lack of early action will jeopardize the achievement of any longer-term mitigation by signalling a lack of political will ([NEED CITE]), or how lack of early action will retard induced technical progress that is needed to make mitigation affordable (Grubb 1995). Sensitivity analyses carried out with IA models suggest that at least some of these criticisms (atacil are not major concerns; others may be serious concerns, but empirical judgments are not possible given the current state of knowledge. The Manne (1996) survey referred to above considered scenarios in which the climate's sensitivity to accumulating GHGs was greater than is typically assumed, or the the damages are larger (by a factor of almost 8) for a given change in the atmosphere. In either case emissions should (from the perspective of maximizing net benefits) be lower, but the extra degree of emissions reductions required by 2010 is significant (on the order of 25 percent or more) only if climate damages are much higher than expected (the sensitivity of the atmosphere to GHG emissions seems much less important in these analyses). And even in this case, emissions still will be higher than 1990 levels unless the atmosphere and the ecological-economic systems both are quite sensitive. (Broadly similar conclusions follow if, instead of looking at higher damages, one looked at damages that grew proportionately faster as atmospheric GHG concentrations grew [CETA cite]). Thus, the IA models give little support for a policy of near-term emissions stabilization unless damages turn out to be much higher than at least some experts expect. It is also true that the results of IA models are sensitive to the choice of discount rate used to compare consumption today and in the future. A very low discount rate will imply greater weight on damages accruing over time to future generations, and thus the need for a more aggressive abatement strategy. This tradeoff is influenced by the rate of economic growth, since growth will make future generations better off and thus better able to afford and respond to the damages of climate change (Schelling 1995). However, there are numerous economic and ethical controversies surrounding the appropriate way to discount future damages in IA models, and no clear consensus has emerged. One important point that is often ignored in this debate is how much today's generation is willing to sacrifice to provide for the increased protection of future generations through GHG abatement; this is a critical unknown since it is today's generation that must necessarily must decide to pay the bill. All that can be said analytically, therefore, is that intergenerational equity might be an argument for more aggressive abatement. Uncertainty about future damages or other influences on the costs and benefits of abatement can make a difference. However, Pizer's (1997) analysis suggests that the most important TOMAN_IA.WPD Page 3 source of uncertainty concerns the nature of our preferences for consumption and environmental protection. (Unlike the Manne (1996) analysis, Pizer considers the possibility that damages may be lower as well as larger.) A recent paper by Gjerde et al (1997) considers the risk of a sudden loss of economic output and well-being on the scale of the Great Depression from climate change. While their analysis indicates more aggressive abatement than other IA analyses without this risk, the introduction 0 the risk has little relative effect on the desirable level of emissions reduction by 2010, and little effect for a number of years thereafter (unless the loss is much larger even than the Depression). This leaves the issues of political credibility and induced technical change. As for the latter, it is true that sending a less strong signal to energy markets will slow up technical progress. However, there is great uncertainty about how much of a loss this would be in practice, and the loss would have to be greater than most models seem to indicate before the substantial costs of near-term stabilization could be justified. This does not mean, however, that no actions are justified on cost-benefit grounds to reduce emissions or stimulate technical progress. Aside from initial steps to curb emissions growth, which signal the need for technical change, longer-term measures to promote the development of new technology are warranted. Political credibility is a more complicated issue to which we return below. 3. Estimates of optimal paths to stabilize GHG concentration levels Much of the debate about GHG stabilization takes as given that simply allowing emissions to continue to grow for a long period, albeit more slowly, puts the biosphere at too much risk and is not credible politically. An alternative strategy [continue with current text] Comments on political credibility to be inserted somewhere in the text Political credibility arises frequently in the discussion of imtertemporally flexible approaches to GHG mitigation. It is argued, that allowing emissions reductions to be deferred to a more distant future invites noncompliance with our domestic obligations, and risks sending a signal to countries not in line for immediate emissions targets that curbing emissions is not a serious matter. Several other points do not seem to surface in this debate and are important to put the issue in context. (1) A proposed agreement that demonstrably imposes much higher costs than an alternative more measured approach, and thereby invites substantial domestic political opposition, will also suffer from credibility problems both here and abroad. (2) The concern about emissions reductions agreements being shirked rather than postponed is a legitimate one, but there are a variety of ways it might be addressed. [Add options here - they should include performance bonds that require carbon debts to be paid back, and (less efficient but more straightforward) simply a backloading of emissions reductions goals in the targets/timetables. The latter may not be credible, but there is little that can be done if a country really sees the burden of successively greater emissions reductions as greater than the cost of noncompliance.] TOMAN_IA.WPD Page 4 (3) Demonstrating willingness to reduce our emissions may not make much difference to the willingness of other countries to reduce their emissions anyway, particularly in developing countries for whom climate change is a low-priority issue. It might be much more effective to take some of the subtantial cost savings from shifting emissions reductions into the future and use them to help develop and diffuse low-emissions technologies that those countries will want to adopt for their own reasons. toman @ rff.org 08/25/97 09:43:00 AM Record Type: Record To: Jeffrey A. Frankel CC: Subject: text on IA models with catastrophe One of the criticisms of many integrated assessments (IAs) is that they do not incorporate the possibility of catastrophe. Recent extensions of the IA literature include the possibility of a major, discontinuous jump inh the damages caused by climate change. For example, a European paper by Gjerde et al (1997) incorporates the risk that climate change will sudenly cause damages equal to a significantr share of global GDP. The risk is assumed to rise with an increase in temperatre from global warming; following Nordhaus (1994), the benchmark risk scenario assumes a 12% chance of a loss equal to 25% of GDP (the scale of the great depression) in 2090 if climate has warmed by 3 degrees C. Incorporating this risk into the IA framework causes the optimal path for global emissions to be reduced, but not by that much in the early years. By 2060, optimal emissions are only somewhat over half what they would have been without the risk of catastrophe, but the reduction by 2020 is on the order of 15% below the no-catastrophe case and still above emissions in 1990. (The no-catastrophe optimal path is fn substantially below BAU in this analysis, an artifact of the assumptions of low abatement cost and high damage cost.) Even sharper emissions reductions are implied if the catastrophe is truly shattering (on the order of the entire GDP), or if the discount rate is extremely low (high intergenerational egalitarianism.)

Hard to reach consensus on AEEI but value is critical. For example, a change from 0.5% to 1.0% cuts projected 2100 emissions levels by half and markedly affects the cost of meeting a CO2 target. Induced technological change in response to price increases is a distinct possibility. Availability and likely future cost of non-fossil backstop energy sources (hydroelectricity, nuclear power, wind and solar energy and biomass) Alternative, low carbon energy sources exist but aren't currently cost-effective. They will become increasingly so as carbon energy sources rise in price and technology makes them less expensive. The availability of these backstop non-carbon energy technologies has a large impact on the costs of meeting whatever emission reduction goal is chosen. Number of years available to achieve a specified CO2 reduction. Merely stabilizing emissions rates will allow concentrations to continue rising for centuries. Recent analysis shows that adopting an explicit-long-term target for atmospheric concentrations and then choosing policies to achieve the most efficient time path for emissions reductions to meet the target could significantly lower the economic impact. A target for concentrations is like a carbon budget limiting CO2 emissions within a specified period of years. Under some circumstances, it is cheaper to use more of the budget early on and postpone cutbacks because the capital stock is so durable. In a system of emissions trading, there should be banking and borrowing of permits to allow flexibility over time. When time is allowed for capital stock to be replaced, overall abatement costs could be reduced. Also, R&D will yield new technologies so postponing costs reduces them. Flexibility in timing of global reductions could lower costs by more than 35% compared to a less flexible program to achieve the same concentration. Under some assumptions, we should adopt a carbon tax now to encourage early development of energy efficient and low-carbon technologies and 11 discourage long-lived investments in carbon-intensive energy facilities. Realistically, action today is likely to be necessary to induce investors to make commitments and not just the expectation of a tax in a decade or more. To quell doubts, a credible policy signal is necessary at the outset--e.g., a carbon tax introduced at a low level that rises, perhaps significantly, in future years. Potential for international joint implementation. This would allow a utility in Norway to achieve reduced emissions by contracting to pay a factory in Poland to install more fuel-efficient furnaces. Finding the lowest cost abatement possibilities is cost effective. л cannot be used more widely until countries have set binding emissions reduction targets. But getting countries to agree on the baselines that should apply to each, from which emissions reductions will be measured is a formidable task. Monitoring and verification and a mechanism to enforce contractual obligations is essential if JI is to work. The potential savings are substantial. Recycling to reduce economically burdensome tax rates or lump sum rebates. Without recycling the carbon tax is highly deflationary, lowering GDP substantially. Lump sum recycling enables a modeler to separate the economic impact arising from climate abatement from that arising from other tax cuts. However, it would be possible to reduce taxes that distort economic activity-- payroll taxes, on investment earnings. Some economists have argued that there could be a double dividend--a gain purely from substituting an energy tax for a more distoring tax on labor or capital income. This is questionable. etc. Benefits in form of avoided economic damages from climate change and other pollution reduction damages. Can avoid pollution associated with auto emissions and higher medical expenditures. Under a reasonable standardized set of assumptions, most models predict a small macroeconomic effect of a carbon tax to stabilize emissions and potentially favorable outcomes. The IAT baseline policy of 1990 by 2010 implies about 26% reduction below baseline emissions in 2020. Looking at all the models we find that, under unfavorable assumptions, GDP would be 2.4% lower in 2020 than under baseline and under favorable assumptions, 2.4% higher. The 4 key influences are (whether there are significant short term adjustments--macro model; whether Л; whether recycling of revenues via reducing other taxes; whether benefits from abating pollution. Under reasonable assumptions, the predicted GDP impact would be neutral or even favorable. 12 A carbon tax might have a disproportionate impact on low income households but it could be offset through other taxes reductions. The impact of a tax on coalmining and coal carrying railway lines would be substantial. However, the baseline predicts a substantial expanison in coal mining in the western U.S. Reduced energy demand in the U.S. would help hold down world oil prices, improving our terms of trade. Impact on competitiveness. If the U.S. alone imposes a significant carbon tax, international trade and investment in some energy intensive industries might shift abroad. However, evidence suggests that differential environmental policies have a weak impact on trade and investment flows and many nonOECD countries have raised energy prices unilaterally. Coordinated international action could avoid these trade effects. 13 MAJOR POINTS: 2000 economists endorsed taking measures to reduce the threat of climate changes on the grounds of the Intergovernmental Panel on Climate Change finding that "the balance of evidence suggests a discernible human influence on global climate." The economists concluded that global climate change carries with it significant environmental, economic, social and geopolitical risks, and that preventive steps are justified. They concluded that proper policies can significantly reduce greenhouse gas emissions without harming the American economy. Some policies could even improve U.S. productivity in the longer run. Market based policies (such as carbon taxes or emissions permits) would lower the costs of control substantially. They said that there are many policies with total benefits in excess of costs. Revenue could be used to lower the deficit or reduce existing taxes. Nations need to cooperate to achieve climactic objectives at minimum costs--international emissions trading. A great deal of controversy surrounds the issue of climate change with some saying that climate change is one of the greatest threats facing humankind and others saying the risks are weakly documented. The same kinds of divides arise in discussing costs and benefits of various policy options. The President believes there is a risk so that policy action is needed, but will look for policy actions that are sensible, cost effective and consistent with continued economic growth and job creation. It is particularly difficult to measure the benefit of climate change action especially when one takes a broad interpretation and thinks about the value of reducing risk related to ecological impacts. Economists differ in their views about emissions policies, some advocating a "broad, then deep" approach in which we begin with a broad but low cost agreement and others favoring a deep, then broad perspective, by first establishing a narrow coalition of developed nations and then reaching out to developing countries to join later via evolution. The problem with the latter approach is that costs rise for a narrow coalition of countries leading carbon intensive industries to migrate and making nonparticipant countries even more carbon dependent. Any agreement without the cost flexibility provided by international trading or JI will at least double the US costs. Models are helpful in understanding implications of climate change policies--give orders of magnitude and sensitivities to assumptions. There is no single correct set of assumptions or appropriate model. It is a mistake to offer just a best guess assessment of either costs or benefits. One should think about ranges of possible outcomes DISCUSSION PAPER THE ROLE OF TECHNOLOGICAL CHANGE TO ADDRESS GLOBAL CLIMATE CHANGE July 30, 1997 Draft PREDECISIONAL DRAFT ** DO NOT QUOTE OR CITE** **PREDECISIONAL DRAFT* DO NOT QUOTE OR CITE DISCUSSION PAPER ON THE ROLE OF TECHNOLOGICAL CHANGE TO ADDRESS GLOBAL CLIMATE CHANGE "In order to reduce greenhouse gases and grow the economy, we must invest more in the technologies of the future. I am directing my Cabinet to work to develop them. Government, universities, business and labor must work together. All these efforts must be sustained over years, indeed, over decades." President Clinton Address to the United Nations June 26, 1997 Context for this paper: The U.S. position on global climate change has consistently been that any action program should be centered on a market-based approach. Given the proper market signals, the private sector will find the most efficient means to make changes in technologies, business practices, and patterns of energy use to reduce greenhouse gas emissions. A properly-designed, capped domestic emissions trading system would provide strong market signals to that end There are also a variety of other technology supporting actions that the federal government could undertake to supplement such an emissions trading system to stimulate R&D and market development in specific areas, where market barriers exist or where changes might be restrained for various reasons. This paper first provides a perspective on the degree of change in energy usage and key technologies that would be needed in key sectors of the economy in order to begin reducing greenhouse gas emissions from energy use. Then, the paper identifies a menu of policy options, for discussion and further evaluation, from which specific elements could be selected to support a technology strategy to both reduce greenhouse gases and continue to grow the economy. This paper provides an initial identification of the options without providing a thorough evaluation of feasibility, impacts, or costs. Additional detailed papers are available from the Department of Energy and others on these technological opportunities. 1 *PREDECISIONAL DRAFT* DO NOT QUOTE OR CITE PROFILE OF U.S. CARBON EMISSIONS IN THE ECONOMY 1990 U.S. Primary Energy Demand (quads) Energy Profiles Three sectors account for approximately one-third of U.S. primary energy demand - transportation, commercial and residential buildings, and industry Transport The electric utility sector supplies about one-third of this demand, virtually all in the buildings and industrial sectors, and consumes fuels to generate that power. In Industry the buildings sector, two-thirds of the energy usage is from electricity, and in industry the share is just over 10% Growth in U.S. energy consumption changed dramatically after the 1973 energy crisis, but is projected to continue growing steadily in the absence of new policies: - the 1960s +52% - the 1990s +12% (already +9% by 1997) - the 1970s +14% - the 2000-2010 decade +12% - the 1980s +11% - in total, 2010 will be 26% above 1990 Carbon Emissions Trends - 1990 - 2020 The profile in U.S. carbon emissions parallels the pattern of energy demand - the three sectors, transportation, buildings, and industry, each account for U.S. Carbon Emissions (mm tons) approximately equal shares Electric utility emissions are double-counted in the sector in which the 700 electricity is used and can only be lowered by reducing electricity demand, by 600 switching to lower carbon content fuels or by carbon sequestration 500 400 Growth projections for emissions parallel the pattern of energy growth. 300 DOE's Energy Information Administration (EIA) projections show: 200 - Total emissions up 28%, or 377 million tons, from 1990 to 2010 100 - Transportation up 43%, or 184 million tons 0 - Buildings up 24%, or 111 million tons Transport Buildings Industry Utilities* - Industry up 18%, or 82 million tons 2020 2010 - Utilities, included in the other sectors, up 30%, or 146 million tons 2000 1990 Utilities emissions also included in final use sector 2 *PREDECISIONAL DRAFT* DO NOT QUOTE OR CITE LONG-TERM TECHNOLOGY STRATEGY In the long-term, over several decades, reductions in carbon emissions will require two fundamental changes, (1) shifts to low-carbon and zero carbon forms of energy, and (2) significant improvements in the efficiency of our energy usage. Appropriate technologies ae the only way to achieve these goals without forcing consumers to give up the services and lifestyles they want. A technology strategy, in combination with appropriate pricing policies, can achieve both goals and provide a strong worldwide position for the U.S. as a technology leader and exporter by advancing improvements such as the following: Trans portation Buildings Industry Electric Utilitie Hydrogen fuels Fuel cells High efficiency motors Renewable energy systems Fuel cell vehicles Control systems Advanced processes - solar, wind, biomass Electric vehicles Materials and structures Materials recycling Distributed power Biofuels Efficient "plug load" Combined heat and power Advanced gas generation Full PNGV 80 mpg vehicles Lighting and equipment Bioproducts/biofuels Superconducting cables, Renewable energy transformers and generators Long-term Market and Economic Uncertainties Electricity deregulation, international competitiveness, increased concern over other emissions and waste reduction Lifestyle trend changes (eg, telecommuting, consumer preferences for large vehicles) Commercial transport shifts in modes, speed, and the role of short- and long-range transportation of goods and people this 1% of 3 Cost Issues Currently, the federal government spends only 1% of its R&D budget, or $600 million/year on long-term energy technologies To achieve these major advances will require significant public and private investment In the long run, it is uncertain whether such technological changes will produce net costs or savings to the U.S. economy Policy Issues Federal and private R&D funding Information and education Public/private partnerships Federal procurement Financing programs Regulations 3 *PREDECISIONAL DRAFT* DO NOT QUOTE OR CITE IN THE MEDIUM-TERM, TECHNOLOGY AND EMISSIONS TRADING PROVIDE A BRIDGING STRATEGY In the medium-term, deployment of currently available, under-utilized technology, or nearly available technology, can serve a "bridging" function to reduce emissions sufficiently to allow time for the long-term R&D developments and the commercialization of various new technologies to reach significant levels. Emissions trading and joint implementation are critical to a technology strategy in providing timing flexibility to deploy efficient technologies at rates close to normal capital stock turnover cycles, and to provide a "safety valve" if the required rates of technological change cannot be achieved fast enough. Both of these steps will help keep costs significantly lower than they otherwise would be. The DOE "Labs Study", the IAT computer modeling, and other studies suggest ambitious rates of change in energy consumption, fuels mix, and technology would be needed to reduce U.S. carbon emissions significantly. For example, the implications of the most commonly evaluated scenario, reducing U.S. carbon emissions to 1990 levels by 2010, would lead to the following: Overall, emissions growth of 28%, or 377 million tons, would have to be avoided or offset If reductions were limited to the U.S., unless large-scale fuel-switching occurred, energy growth would probably have to drop to half its present rate, to about 10 to 12% over the 20-year period, and it's already about 9% above 1990 levels in 1997 With emissions trading and joint implementation, the models suggest that up to 40% of the 2010 emissions reduction might be achieved abroad, at U.S. expense, to buy time for a more orderly technological transition here The key in the latter case would be to encourage, through pricing and other means, the utilization of the most efficient or low-carbon technologies when Emissions Stabilization by 2010 (mm tons) capital stock is being installed or replaced on its regular cycle Illustrative Scenarlo 700 Transportation 600 In the absence of international emissions trading, growth in energy usage by 500 400 2010 would have to drop to about half its projected growth rate of 30% to 300 40%, down to 15% to 20% 200 On-road fuel economy for all cars and trucks (new and existing) would have 100 0 to reach 25 mpg by 2010, from its present level of 20 mpg Transport Buildings Industry Utilities Through PNGV, government is partnering with automakers and expects to develop new automotive technology that can triple the fuel efficiency of a 1990 2010 BAU No Trading Trading 4 PREDECISIONAL DRAFT* DO NOT QUOTE OR CITE MEDIUM-TERM continued models Is typical family sedan while meeting stringent emissions and safety standards and maintaining affordability, performance and utility. Production prototypes are expected by 2004 One pathway to achieve an on-road fuel economy of 25 mpg would require about 30% of new light duty vehicles to meet the PNGV goal by 2010. Alternatively, all new cars and light trucks could incorporate 30% of the improvements represented by the PNGV goal by the 2010 model year for 45 mpg new automobiles Currently projected higher costs of PNGV improvements would pay for themselves in fuel savings within 4 to 5 years With international emissions trading, the pace of improvements could be slower, but would likely still need to show significant improvement in fuel economy over present vehicles Commercial and Residential Buildings Without emissions trading, growth in energy usage in buildings would have to be cut in half, to a rate of about 10% by 2010 Technologies needed to achieve these savings largely exist today. No major breakthroughs are needed. Over the next decade, most buildings could be cost-effectively improved to use 30% less energy while delivering the same comfort. To achieve the needed efficiency savings by 2010, approximately 35% of the equipment that normally would be installed or replaced in buildings by then needs to be cost effective, high efficiency equipment Technology deployment programs such as EPA's and DOE's Energy Star labeling, Rebuild America, and Green Lights programs, are currently working to inform consumers and businesses of efficiency and cost savings opportunities Industry Without emissions trading, energy growth would have to be almost flat at 1990 levels, instead of increasing about 20% by 2010 Increased use of heat recovery, cogeneration, and more efficient motors offer the greatest generic opportunities, with other specific technologies also available in individual industrial sectors, such as those detailed in DOE's "Industries for the Future" cooperative program with seven major energy-intensive industries 5 *PREDECISIONAL DRAFT* DO NOT QUOTE OR CITE With emissions trading, modest emissions and energy growth of around 7% by 2010 could be possible Industrial energy efficiency has improved since 1972, now requiring just 67% as much energy per unit of output Electric Utilities Without international emissions trading, utilities would likely have to make absolute reductions on the order of 30% in carbon emissions below 1990 levels, in order to offset the increases above with even substantial reductions in energy growth rates in buildings and industry, while at the same time supplying more electricity to customers Renewable energy sources would increase by 25% Combined cycle natural gas plants today can generate electricity while emitting about 2/3 less carbon than many existing coal plants. Natural gas would roughly double its 1990 usage in the industry Coal usage would have to drop to about one-third to one-half the 1990 level, while natural gas use would increase from 50% to three times its 1990 level appear inconsistent With emissions trading, the coal-to-gas shift could be less severe, but electricity demand would also rise faster. Overall, emissions would still probably have to be about 10% below 1990 levels in 2010 Shifts in the utility sector would offer other substantial air quality benefits. For example, fuel shifts and increased use of advanced technologies could reduce Nox emissions by over 1/3. Costs How much these changes would cost the U.S. economy is uncertain. In some recent experiences, such as with the Montreal Protocol on ozone depletion and the sulfur dioxide emissions trading system under the Clean Air Act, actual experience has turned out to be substantially less costly than expected because market incentives were used The interagency economic modeling analysis indicates that the economic incentives needed to reduce emissions to 1990 levels by 2010 would be in the range of $100 per ton if all of the reductions were made domestically, about $50 per ton with international emissions trading among developed countries, and as low as $20 per ton if both international trading and joint implementation were available DOE's "Labs Study" identified those technological changes that were estimated to be cost effective at an emission allowance price of approximately $50 per ton needs to note that they achieved 1990 in 2010 e $50 e *50/ton 6 *PREDECISIONAL DRAFT** DO NOT QUOTE OR CITE The true, net cost of such emissions reductions would depend significantly on how the revenues from any emission allowance sales were recycled into the economy, and upon the degree of cost savings experienced due to reduced energy costs. The DOE "Lab Study" projected that the majority of costs would be offset by energy savings, with net costs as low as $10b annually in 2010 Policy Issues A commitment to cap carbon emissions would provide an immediate incentive to invest in energy efficiency, but because of market imperfections, some additional measures could be needed to stimulate R&D, commercialize new technologies, and purchase and use advanced technologies as capital stock turns over in the economy 7 *PREDECISIONAL DRAFT** DO NOT QUOTE OR CITE net cost DOE'S 'Labs Study' "SCENARIOS OF U.S. CARBON REDUCTIONS The Potential Impact of Energy-Efficient and Low-Carbon Technologies" THE REPORT'S CONCLUSION Technology can lower the net cost of stabilizing carbon emissions at 1990 levels in the medium term (i.e., 2010) to less than $10 billion a year or less (0.1% of GDP). International trading or flexibility in meeting a stabilization target, considered by other studies, could reduce costs by another 50% or more. The study assumes penetration of technologies from expanding Administration initiatives, such as the PNGV, natural gas technologies, the Climate Change Action Plan and renewable energy such as wind and biomass. BACKGROUND Five DOE national laboratories, led by Oak Ridge and Lawrence Berkeley National Laboratories, have conducted a comprehensive, extensively peer-reviewed, 1 year "bottom-up" analysis of the role technology can play in stabilizing U.S. carbon emissions. It is the most authoritative and documented study of this subject since the National Academy of Sciences report and the Office of Technology Assessment Report in 1991. The study documents in detail how four key sectors of the economy-buildings, transportation, industry, and electric utilities-could respond to a climate treaty if launched in the year 2000 with a goal of stabilizing emissions in 2010 and a U.S. cap and trade system is phased in with gradually rising permit prices. The National Laboratories study examined what effect an aggressive program of research, development, and development of clean technologies could have if combined with alternative marginal permit prices of $25/ton and $50/ton of carbon (the average permit price is much lower). RESULTS The study concludes that energy efficiency and low-carbon technologies have a very large potential to cost-effectively reduce U.S. carbon emissions while meeting the full energy needs of U.S. businesses and families. Many consumers and businesses will save money. 8 *PREDECISIONAL DRAFT** DO NOT QUOTE OR CITE Under moderate technology and market assumptions, energy efficiency technologies alone can reduce emissions in 2010 by 120 MMT (of the 380 MMT needed to stabilize at 1990 levels). This level of carbon reduction is estimated to be possible at little or no net cost - that is, the energy bill savings far exceed the investments required to achieve the carbon savings. Under more aggressive assumptions motivated in part by a $25/ton carbon permit price, a combination of energy efficiency, low-carbon technologies and relatively inexpensive coal power plant conversions to natural gas can reduce 2010 emissions by a total of 225 MMT. Under a $50/ton carbon permit price, technology investments reduce 2010 emissions by a total of 380 MMT. The analysis also suggests that substantial additional savings are available if permit prices were to begin to rise above the $50/ton level. The annual investment costs of reductions of this magnitude are estimated to be $50 to $80 billion per year, but result in substantial energy bill savings. The resulting net costs are on the order of -$25 to +$10 billion per year in 2010. METHODOLOGY In contrast to the top-down economic modeling of the Administration's interagency team, the five laboratory study uses a bottom-up technology-by-technology assessment as well as top-down engineering-economic modeling approach. It draws upon a wide variety of technology cost and performance information to assess potential impacts. It has been peer-reviewed by industry and academic experts. Analysis of the buildings, industry and transportation sectors quantifies the impacts of end-use energy efficiency improvements on carbon emissions. A utility sector analysis estimates the impacts of those improvements on utility carbon emissions, and quantifies additional emissions reductions through changes in operations and conversion of a number of coal power plants to natural gas. Finally, a number of promising very low carbon technologies are examined to determine their potential for emissions reductions, including advanced gas turbines in industry, biomass power, transportation biofuels and improved aluminum smelting. TOTAL BENEFITS EXCEED TOTAL COSTS In the long term, these climate change mitigation actions will provide additional benefits not fully considered in the study - reductions in criteria air pollutants (i.e., ozone and fine particles), decreased dependence on foreign oil, greater industrial productivity, and U.S. leadership in technologies are likely to be a major source of international trade and jobs in the next century. This report provides details on the technologies that can potentially achieve the energy usage and carbon emissions reductions necessary if the U.S. commits to a scenario like the one outlined in the sections above, which would return U.S. carbon emissions to 1990 levels by 2010. 9 **PREDECISIONAL DRAFT** DO NOT QUOTE OR CITE POLICY OPTIONS FOR A U.S. TECHNOLOGY STRATEGY GOALS To develop a set of policy options that can help establish the appropriate price signals in the economy, and then provide a set of supplemental actions that will help overcome market barriers and otherwise facilitate an efficient response in the private sector: encouraging manufacturers, builders, etc. to produce high efficiency equipment, systems, materials, etc. stimulating consumers and purchasers to accelerate their acquisition and use of those technologies encouraging the development of financial, service, and other infrastructure to support those technologies A MENU OF POLICY OPTIONS Prices in the economy - Valuing carbon emissions rights, through a "cap and trade" system, which should be more efficient and less costly than individual subsidies and incentives - Investment tax credits, special depreciation treatment, differential fuel taxes (such as the ethanol tax credit), or other financial incentives through the tax system - Feebates, or complementary product fees and rebates depending upon product energy efficiency Financing - Enhance availability of financing through partnerships and innovative instruments with financial organizations - Incorporate incentives into federal loan, loan guarantee, and grant programs to promote high efficiency technologies Federal R&D policy - National public/private initiatives in key technologies, modeled after the Partnership for a New Generation of Vehicles, eg: in DOE's 7 "Industries of the Future" programs for Pulp and Paper, Chemicals, Petroleum Refining, Glass, Aluminum, Iron and Steel, and Metal Casting in DOE's "Buildings for the 21" Century" program for residential and commercial buildings - Increased federal funding for R&D, pilot projects and demonstrations leading to commercialization and/or wider availability of new technologies - current federal funding is just over $600 million annually - "Bonus Emissions Credits" under a cap and trade system to reward development and deployment of advanced technologies - Incentives for utility sector technology R&D incorporated into utility industry restructuring at the Federal and State levels 10 *PREDECISIONAL DRAFT* DO NOT QUOTE OR CITE Continued POLICY OPTIONS continued Market transformation - Market aggregation, for local governments and companies to coordinate purchases for greater influence - Business-government partnerships to provide information, demonstrations, and technical assistance - Field verification of advanced technologies Federal leadership through procurement - Federal agencies "lead by example" by adopting aggressive policies to implement energy savings and renewable energy technologies at federal facilities, and to acquire and use more efficient and alternative-fuel vehicles in federal fleets - Broaden the participation in Federal Energy Savings Performance Contracts which DOE is implementing to leverage private sector financing through third party energy services companies to reduce the federal government's $8 billion annual energy bill - Executive Orders to provide clear direction and management flexibility for greenhouse gas emission reductions within agency plans and programs - Green Power Purchasing, by which agencies can negotiate contracts to supply a fraction of their electricity from renewable energy sources Regulation and standards - Appliance efficiency standards, negotiated with the industry and public, such as the recent refrigerator standards - Building energy efficiency codes, implemented at the local, state, and federal levels, as appropriate - Expedited environmental permitting for highly efficient or low carbon technologies - Coordinated implementation of National Ambient Air Quality Standards with climate change policies - Restructuring of the electric utility industry in a way that facilitates investment in new and renewable technologies Information and education - Voluntary or mandatory energy performance labels to internalize the asset value of energy efficiency, such as efficiency labels on appliances, vehicles, computers, equipment, and commercial and residential heating and air conditioning systems - Federally-supported multi-media materials development for use in schools and the mass media International market development - Special focus on bilateral trade agreements, export assistance, and financial assistance in support of U.S.-produced advanced technologies for energy efficiency, renewable energy supplies, etc. 11 **PREDECISIONAL DRAFT** DO NOT QUOTE OR CITE BACKGROUND ON KEY SECTORS The material on these pages provides brief, thumbnail sketches of six key sectors of the economy, listed below.

Larger reductions are possible beyond 2010 if hydrogen-powered, fuel cell powertrains are developed and commercialized for truck transport. Also, a more aggressive technology scenario might include advanced diesel engines, rapid penetration of diesel trucks that are 25 percent more efficient than current diesel engines.

As estimated by DOE, the incremental production cost of renewable electricity is estimated to be $2-3 billion/yr in 2010 and negligible in 2020 as multiple renewable technologies are widely competitive with gas technologies.

Carbon emissions are 700 now at about 33 percent or total emissions in the United States, or 464 600 of 1424 million metric tons (MMT).

The use of heat recovery and combined heat and power (i.e., cogeneration) systems such as the Advanced Turbine System, can reduce industrial carbon emissions by up to 35 MMT/year in 2010 with electricity costs that are 10 percent lower than current systems. Motor systems account for 70 percent of industrial electricity use (about 120 MMT). Better designed energy-efficient motor systems could reduce electricity use by up to 40 percent. Better maintenance of compressed air systems can also save 40 percent of the energy used in such systems. In addition, there are important longer term opportunities to reduce the carbon intensity of industrial operations through changes in the fuel mix, and by using lower-carbon fuels. Costs There are readily-available but underutilized technologies with two to four-year paybacks that can reduce industrial energy use by 10 percent or more. As referenced above, these technologies include more efficient motor systems, air compressors, and process efficiency improvements. DOE estimates that the cumulative investment necessary to reduce industrial carbon emissions to 1990 levels by 2010 is on the order of $47 to $58 billion in the period 1998-2010. On an annual basis, this is about 3-4 percent of the total investments made by the manufacturing sector in 1995. By 2010, annual energy savings are estimated at $8-10 billion (with all values in 1995 dollars) -- approximately a 17% to 20% return on investment. Many of the most successful technologies have multiple benefits, including environmental- or productivity-enhancing may actually improve the competitive position of many industries. Policy Challenges Policies to encourage the more rapid diffusion of existing technologies include: (1) incentives to accelerate the investment in new capital stock and equipment; (2) increased RD&D to facilitate the development of improved technologies as well as the development of a new generation of industrial technologies; (3) incentives to increase the use of recycled feedstocks; (4) expediting the use of combined heat and power systems through improved environmental permitting and by incorporating provisions into the ongoing utility restructuring that facilitate the sale of excess power by industrial plants; and finally (5) a life cycle approach to environmental permitting and regulations. 24 16:17 MAY 19, 1997 ID: RFF TEL NO: 202-939-3460 #5317 PAGE: 2/3 Executive Office of the President Council of Economic Advisers MAY 19, 1997 MEMORANDUM FOR: JASON SHOGREN CC: TOM RHOADS FROM: MIKE TOMAN SUBJECT: "JOINT IMPLEMENTATION" SOME DISCUSSION POINTS You asked me to prepare some general points that could help guide CEA's thinking on how joint implementation should be structured. Here are some general issues that need to be emphasized, in my view: (1) Transactions costs. On the one hand, it is true that the potential cost savings from JI for US emitters are high enough that some transactions costs can be borne; and that some should be borne to develop a system that is environmentally and politically acceptable. On the other hand, past experience with emissions trading programs indicates that transactions costs can cripple trading when there is no effective way to manage them. In this regard. for example, it would be very counterproductive to require too many reviews of л proposals and performance from too many parties, especially third parties who may have idiosyncratic interests and bear no costs for frivolous challenges. There is simply no way to manage that kind of risk, and the rational response of both investors and hosts will be to eschew many if not most possible projects. It makes a lot more sense to have the project reviewed at the proposal stage, and then again after a number of years (perhaps with random spot-checking; annual review is too burdensome and doesn't provide scope for inevitable fluctuations in performance). If projects are found to be in default, then whoever is responsible could be required to make restitution. The simplest way to do this would be to require the emitter to retire an offsetting number of other carbon credits plus a penalty, though putting all the burden on the credit buyer creates its own adverse incentive problems (presumably insurance mechanisms could develop; this was a major point of contention in the development of EPA's Open Market Trading Rule for O3 and VOCs). (2) Additionality: these issues are in some ways extensions of the points above. There is considerable concern about how to determine whether certain emissions reductions wouldn't have happened anyway, leading some to conclude that there should be no JI (trading should only take place within Annex 1 countries with national caps), or at least that JI should be restricted in various ways. Additionality is a practical concern, but we have a lot of time (several years) to work out some sensible, transparent, easily implemented protocols. Analysts at the IEA and OECD, among others, already are engaged in this process, and it should be allowed to run its 16:18 MAY 19, 1997 ID: RFF TEL NO: 202-939-3460 #5317 PAGE: 3/3 course. We should not let our current uncertainty about how to address the problem freeze us into a very restrictive posture toward JI in the long term. In particular, we need to watch out in trying to early to establish an "approved" list of Л project types that qualify for additionality, since this is the way de facto design standards get created. (We do need to think about sequestration differently from emissions reduction, but that is a specific narrower question.) (3) "Paper Credits" and "Leakage:" A related question is whether it makes sense to have trading involving non-Annex 1 countries, since their emissions are likely to be growing anyway. This view reflects a basic misunderstanding of what JI is supposed to do. It is supposed to provide a way to reduce the cost of achieving whatever emissions reductions targets are negotiated; and in the process, it can provide a valuable spillover benefit by introducing climate-friendlier and economically beneficial technologies into developing countries, reducing their baseline emissions growth. If emissions reductions are additional, they necessarily are making emissions growth slower than would otherwise have occurred. (4) Discounting credits: some arguments have been made that Л credits should be discounted to reflect a variety of factors, including uncertainty about additionality and monitoring, leakage, and the desire to get non-Annex 1 countries into the Annex 1 trading system. As suggested above, I think the leakage argument is specious. Discounting for uncertainty is possible, but it needs to be handled with great care lest any incentives to improve performance be taken away, or that discounting introduce an untoward bias in favor of some technology types over others. Better to just get people to improve monitoring. Finally, discounting to induce participation in Annex 1 trading has it all backwards -- these countries are supplying a valuable service to us with JI, not the other way around, and we should not be impeding the supply of that service. They do not at this point have much incentive to opt into a national cap and trade system just because we shoot ourselves in the foot by discounting JI credits. I hope these thoughts are useful.

By definition of the models, these emission reductions has zero or negative costs associated with them. Most of the studies indicate that emissions can be kept at or below base year levels for about 20 years. The OTA and MARKAL studies indicate steadily rising emissions while the AEC study indicates steadily falling emissions thereafter; the difference reflects different assumptions about technology opportunities in the future. The EIA study considers only energy efficiency improvements and is unable to match the others in terms of identified cost-effective opportunities. Exhibit 4 illustrates the lowest-carbon run undertaken by each U.S. study. The EIA study results in only modest additional reductions in carbon emissions. All of the other studies are able to reduce emissions below the base year. AEC reduces carbon emissions by 40 percent by the year 2010. Exhibit 5 indicates the assumptions and cost-results for these studies. Only the most aggressive carbon reduction case is included. For all but the MARKAL study, the investments include a mix of those that save more than they cost ("no regrets") and those that cost more than they save (for MARKAL, all measures have positive costs). The resulting average costs may be positive (OTA, ICF, MARKAL) or, negative (ABC, OTA). Marginal costs - the cost of the last ton of carbon saved tend to be significantly higher than average costs, indicat that costs rise as the stringency of the carbon limit increases. (Average costs actually fall in the AEC study as the stringency increases, even though marginal costs rise. This is due to "no regrets" investments being brought in faster in the more stringent scenario.) Economy-wide cost estimates. The Energy Modeling Forum at Stanford University brought together 8 number of economic modelers to analyze carbon taxes, and they differed by a factor of 5 in their conclusions as to how large a tax would be required to achieve specific emissions goals. To the extent possible, key assumptions were standardized across models. Most of the acenarios examined in the models assume initial reduction steps beginning in 1990. Scenar 05 in which emissions reductions do not begin until 2000, and begin from the higher base level projected at that time, would likely engender higher costs. Exhibit 6 tabulates model estimates of U.S. GDP costs of emissions reductions. Stabilizing emissions at their 1990 levels is generally estimated to reduce GDP by .2 to .7 percent in the year 2010, a $20-70 billion loss for that year. One macro study, however, estimates the costs to be approximately 3% of GDP. These estimates assume a lump sum redistribution of tax revenues, with no incentives effects on marginal tax rates. GDP losses increase as the emissions target gets more stringent: estimated GDP losses in 2010 with a 20 percent reduction from 1990 range from .9 to 1.7 percent of GDP. Estimates range from $20 to $150 per ton for the carbon taxes required to hold emissions at 1990 levels in 2010. To achieve a 20 percent reduction, model estimates range from $50 to $330 per ton. High carbon taxes were required in models that assumed a low price responsiveness to higher energy prices and slow adjustment of the capital stock. Note however, that the above estimates are based on a pro-specified set of economic assumptions imposed upon the modelers. When modelers are free to choose the economic assumptions they consider most likely to materialize, the range of cost estimates is much wider. For example, Montgomery, Hughs, and Yanchar (Global Climate Coalition) estimate that even a $200 per ton tax, causing a 4.3% GDP loss, would be insufficient to attain the 20 percent reduction goal by 2010. This same point applies to OECD and world estimates.

Domestic Emissions Trading upstream We are now working with EPA on a paper that will cover four options, representing the convolution of upstream/downstream and auction/allocation (SQUITIERI). 1. Heavily revise EPA's version of the two upstream options (target: 9/5) 2. Receive EPA's version of the two downstream options (target: COB 9/4), and provide comments (target: COB 9/8). These comments probably only need to state our objections, and hit the low points. see a previons paper for background 3. Develop a clear written explanation of why we oppose tradable credits. Key points should include the inefficiencies of CAFE-like approaches (doesn't penalize intensity of use, impacts only market for new units, not existing); should draw on empirical literature concerning the cost of the CAFE standards relative to a gasoline tax (target: COB 9/8). 4. Gardiner wants to talk things through face-to-face (especially our visceral opposition to downstream options) after we've had a chance to look at the downstream stuff. After that we can decide whether we need to append a statement to the effect that "the downsteam options are vigorously opposed by the economics agencies." 5. Wrap-up (target: COB 9/10?) II. Technology A. GILLINGHAM and ALDY to draft stand-alone technology paper. [Might include an argument along the following lines, supplied by Summers: Even if you accept the 5labs report lock, stock and barrel, you get only X percent of the way there without raising price. To get all the way there, you have to raise price by Y percent. This would have the following implications for energy prices-x for coal, y for gasoline, etc.-and would be roughly Z times as large as the BTU tax that was proposed early in the first term.] Transmit to D.

If most uncertainty derives from aggregate demand shocks, then we might not need (or even want) an escape clause. If most uncertainty derives from shocks to technology, escape clauses seem very important.) D. Paper on competitiveness - (status?)

However, this decline in employment has been met with a modest increase in absolute coal production over the same time period, particularly due to the increased mining of subbituminous coal and lignite, thus indicating an increase in worker productivity. Per capita real wages, which slowed down in 1979 after considerable growth in the ten years prior, have only recently begun to increase. In the event of a substantial carbon tax, it is very likely that the coal mining industry would suffer greatly. With more than 80% of the workforce above the age of 35¹, it is unlikely that any significant amount of displaced coal miners could be retrained for careers in other fields. The states that would be affected most greatly by a carbon tax are West Virginia, Kentucky, and Pennsylvania, which cumulatively account for 53% of all U.S. coal miners. The region that would be hit hardest is the Southeast, where almost 56% of all coal miners are employed. ¹According to estimates from the Bureau of Labor Statistics that cover the period from 1992-1996.

Dear Adelle, It is always a bit frustrating to me at these meetings when we open a topic and then move on without concluding it. I wanted to say a bit more about your nomination of the pure seller liability option, but I couldn't get speaking space at the right time. At the end of the meeting Jonathan kept pure seller liability on the table, saying that he had heard some in favor and no fatal criticsim. His motivation may have included the fact that some of the "big guys" have spoken favorably of pure seller liability and you can't go against the big guys. I assume that you defended the idea either because you favor it, or because you have not seen the group make a sufficient (dismissive) critique and you want to hold US to a high logical standard (perhaps as devil's advocate) or perhaps for other reasons. Anyway, I think there are some imporant negatives about strict sellers liability that have not yet been aired. So here is my view of pure seller liability. From a simple feasibility perspective I think pure seller liability is tough to implement. The transaction may occur in year 1, but the final validity of the allowance sold may not be determined until year 5 or later. By the time the liability, if any, of the seller is known the sale is so distant that the proceeds may be gone and the liable sellin country seller may be unable or unwilling to pay. An escrow is not a perfect answer because the time period is so long. Escrow impounds are usually for fairly short period while exposures are actively resolved, not for long periods. Surety bonds are not the right tool in this case either. Next, for true versions of pure seller liability we need to have the seller liable, not the alternative form in which the buyer is liable with access to a legal remedy against the seller. That would impose too much of a burden on buyers by allowing them (i.e., forcing them) to pursue sellers to make good on promises to buyers. Chasing a seller and even getting a judgment is far different from getting payment on that judgment. Seller liablity should mean that the Fccc Secretariat undertakes to collect directly from the defaulting seller in the event of default. Can we really imagine the FCCC Secr. going after defaulting Parties? Especially in light of the option that any Party has to quit the agreement? In light of the long period between the sale and a potential default finding, the questionable ability of the FCCC/Secr. to enforce against the selling Party no matter how quickly it can proceed, and the opportunity of any seller to simply quit rather than face an onerous penalty make seller liability a non-feasible choice. This door must be locked before the horse has escaped, not five years after. I think the only feasible choice is to make the sales proceeds reflect concurrent compliance probablities, so that sellers get about the right revenues from the start so as to minimize the need for subsequent adjustments. I think escrow and insurance schemes are also unworkable answers for this case. Insurance is defeated by the moral hazard aspects of this problem. In the dynamic, insurance charges have to be experience rated. Here, experience rating will tend toward a 100 percent premium for the worst issuers. at any lower premium they have an incentive to take the money from sales and default in the polar case. An the polar case is what you get since performance (or non-performance) is fully within the control of the insured. Control by the insured over the insured outcome is the classic hallmark of an uninsurable event. Likewise for escrow, apart from the earlier point about the long duration of the escrow, for the big defaulters, if any, an escrow of less than 100 percent will create an incentive to default for a financial gain. But any large escrow interferes with use of the revenues for energy efficiency investment and monitoring costs and in a way increases the chances of default. For the bad guys any escrow will be too small; for the good guys any escrow will be too large. In either case revenues will be denied for valid purposes. I come back to the same conclusion, that we need some way to limit revenues to the expected value of allowances at the time of the transactions. I still like the market verdict on sale prices with constant market review. I don't think the FCCC SEcr. will ever get the authority to make discretionary judgments against the soverign Parties.

Trading in emission allowances involves a mix of characteristics from both commodity and bond market trading. Safeguarding the environmental values and the interests of trading participants requires a blend of practices from these two markets. Trading raises the importance of enforcing compliance, since non-compliance is the route to financial profit and trading allows Parties to put into circulation some allowances that might lie dormant without the trading opportunity. Neverthcless, with trading the required compliance rules are the same ones needed for ordinary compliance. The integrity of emissions limits will be strengthened if Parties that fail to meet compliance requirements, especially if they are net sellers of allowances, can be held liable for their non-compliance. In commodity trading, the concept is "what you see is what you get." Once the commodity specification is written, conforming delivery is secured by the certain prospect of secured cash penalty in the absence of conforming delivery. For trade in gold, for example, performance by the seller requires timely delivery of specification-grade gold. The delivered commodity itself is sufficient evidence of its own validity. By contrast, trading in bonds, representing a promise of the issuer's performance, requires continual assessment of the underlying promise to pay, in order to determine value and prices. Trading in emission allowances can be pushed to either model. Emissions trading via instruments whose compliance value is guaranteed by the international authority is like commodity trading. So long as the guarantee is trusted, the allowances can trade as a commodity; what you see is what you get and a tonne is a tonne. The value of an allowance derives from its guaranteed compliance value. By contrast, if the authority reserves the right to adjust the compliance value of the allowance based on some subsequent occurance, then trading is more like bond trading and the value of the instrument depends on market assessment of the promisor's likelihood of performance. How, and even whether, allowances will trade and be valued depends whether their compliance value is guaranteed or subject to adjustment for conditions outside the control of the holder Seller vs. Buyer liability for non-compliance: Pure seller liability: A seller would unconditionally guarantee attainment of its adjusted emissions target in support of any allowance sale. This is a commodity market model, but unlike most commodity trades, compliance may not be determined until long after allowance sales; the power to compel subsequent cure of a compliance deficiency, or to exact indemnity from a sovereign Party that is unwilling or unable to cooperate, is lacking. Seller liability may be impossible to enforce. Modified seller liability: All sellers would agree, in advance, to escrow a share of allowance sale revenues or provide 3rd party performance bonds for their end-of-period emission compliance obligations. This plan has the disadvantage that some net sellers will be counting on their 16:32 MAR 31, 1998 ID: EPA OAR-OPA LINE2145 TEL NO: 000-0000 #14845 PAGE: 3/4 allowance sales proceeds to cover monitoring costs and the cost of investments to further improve energy efficiency and emission performance. Performance bonds may be costly for the Parties that need them most. Insurance is not viable because the insured event is too much subject to the control of the insured Party and the Party may, in the short-run, gain more from default than from compliance. The insurance cost will be unfairly high for those who comply and too low for those who default. The issue is akin to the 1980 S&L problem. The problem is summarized by the economic term "moral hazard" and creates incentives for a downward spiral toward progressive non-compliance and the parallel withdrawal of all insurers. Pure buyer liability: Under this option, buyers of allowances can use (tender) them for emissions compliance (i.e., receive the anticipated value) only to the extent that sellers retrospectively, meet their emission commitments. This is a bond market model. The determination of compliance value is made long after some sales occur. Unless buyers can get effective guarantees of performance from the originator of purchased allowances or reliable assessments of risk, the buyer holds a very uncertain instrument. This risk, even in small doses, is unattractive to buyers and even less attractive to traders. Buyer liability for sellers' future emissions performance would likely be fatal to emissions trading, where, unlike the case of "full faith and credit" guarantees, secure guarantees of performance across national boundaries are unlikely. Modified buyer liability: If the FCCC Secretariat held the power to deny compliance tender value to allowances not supported by emissions compliance of the first issuer (a bond market model), the direct compliance burden would fall on buyers, but an informed market could achieve substantial shifting of the compliance burden to sellers. For example, allowance trading could be conducted according to these rules: Traded allowances are identified as to original nationality and serially identified by date of their first recorded trade. For untraded allowances, the date of submission to the FCCC Secretariat for compliance determines the serial priority, In the event of a Party's non-compliance, some allowances originating from that Party would be invalidated, starting from the latest dated allowances and proceeding backward, until the remaining quantity matched the Party's compliance achievements (i.e., domestic emssions do not exceed retained allowances, and exchanged allowances do not exceed avoided emissions), Annual reports would reveal each Party's compliance progress (emissions) and AEU sales rate, thus permitting the market to assess how many allowances from each Party are likely to be valid, and a quality-adjusted price for each point in the serial sequence, Market prices for allowances would reflect expected probabilities of validity. Private tools, such as rating services, compliance consultants, derivative contracts, and portfolio syndications would arise to permit risk management strategies. Market information, both public and private, would permit shifting of risk exposure back to sellers through the market prices that informed buyers would offer for allowances of varying probable value. In the end, each allowance would be good or bad; all good allowances would have the same compliance value. Market information would permit a gradual sharpening, over the course of the budget period, of the price differential between expected good and bad allowances around the expected validity cut-point for each Party. 16:33 MAR 31, 1998 ID: EPA OAR-OPA LINE2145 TEL NO: 000-0000 #14845 PAGE: 4/4 Direct imposition of compliance burdens on buyers, but with substantial information given to sellers, can create a hybrid system of liability that shifts a significant share of the compliance burden to sellers and creates a significant market incentive for seller compliance, even when the direct compliance process is administered on buyer/holders of allowances. Private steps in the trading process following emission assignment under the FCCC with modified buyer liability rules: Parties may, at their option, assign some allowances to sub-national entities. Holders may offer to sell allowances, to be identified by nationality and serially numbered in ascending order. Buyers offer prices, based on assessment of end-of-period compliance of seller. Highest prices will be offered for first issuances, which are the first to be honored within each nationality class. Later issuances carry greater risk of non-compliance bumping and will generally command lower prices. Rating agencies could offer assessments of the likely validity cut-off point for each issuer. Prices of allowances traded would reflect market consensus of future validity with continual adjustment of perceptions as compliance expectations change. Parties that show credible compliance reports will get higher prices for larger proportions of their sales offerings. Poor reports will limit the opportunity to sell allowances except at very low prices and for limited quantities. Speculators might enter to buy cheap allowances to rehabilitate them prior to the compliance date. At the end of the compliance period, FCCC Secretariat announces which allowances are valid. Nations make compliance tender of valid units and added compliance, as needed, to complete compliance. Supplemental compliance methods, like borrowing from the second budget or an agreed "excess emissions fee" will be needed to permit national compliance in the event that insufficient valid allowances remain to permit first period compliance. Official steps in the trading process under modified buyer liability rules: Emissions amounts assigned to Parties, Compliance authority agrees to permit allowance trading, Following any sale, the recording agent accepts joint order to record transfers; The recorder notes the nationality and places a serial number on newly-recorded allowances, and maintains the existing identifiers for previously traded allowances. At the end of the budget period, FCCC Secretariat announces which allowances are valid for compliance, based on the compliance showing of each issuer that traded. Parties supplement surviving allowances, if necessary, to complete compliance by borrowing, open market purchases, or pre-specified default payments. Prelim.

Trading in emission allowances involves a mix of characteristics from both commodity and bond market trading. Safeguarding the environmental values and the interests of trading participants requires a blend of practices from these two markets. Trading raises the importance of enforcing compliance, since non-compliance is the route to financial profit and trading allows Parties to put into circulation some allowances that might lie dormant without the trading opportunity. Nevertheless, with trading the required compliance air rules are the same ones needed for ordinary compliance. The integrity of emissions limits will be strengthened if Parties that fail to meet compliance requirements, especially if they are net sellers of allowances, can be held liable for their non-compliance. In commodity trading, the concept is "what you see is what you get." Once the commodity specification is written, conforming delivery is secured by the certain prospect of secured cash penalty in the absence of conforming delivery. For trade in gold, for example, performance by the seller requires timely delivery of specification-grade gold. The delivered commodity itself is sufficient evidence of its own validity. By contrast, trading in bonds, representing a promise of the issuer's performance, requires continual assessment of the underlying promise to pay, in order to determine value and prices. Trading in emission allowances can be pushed to either model. Emissions trading via instruments whose compliance value is guaranteed by the international authority is like commodity trading. So long as the guarantec is trusted, the allowances can trade as a commodity; what you see is what you get and a tonne is a tonne. The value of an allowance derives from its guaranteed compliance value. By contrast, if the authority reserves the right to adjust the compliance value of the allowance based on some subsequent occurance, then trading is more like bond trading and the value of the instrument depends on market assessment of the promisor's likelihood of performance. How, and even whether, allowances will trade and be valued depends whether their compliance value is guaranteed or subject to adjustment for conditions outside the control of the holder Seller vs. Buyer liability for non-compliance: w sde liable so Pure seller liability: A seller would unconditionally guarantee attainment of its adjusted emissions target in support of any allowance sale. This is a commodity market model, but unlike most commodity trades, compliance may not be determined until long after allowance sales; the power to compel subsequent cure of a compliance deficiency, or to exact indemnity from a sovereign Party that is unwilling or unable to cooperate, is lacking. Seller liability may be impossible to too quickly dismused enforce. (?) Modified seller liability: All sellers would agree, in advance, to escrow a share of allowance sale revenues or provide 3rd party performance bonds for their end-of-period emission compliance obligations. This plan has the disadvantage that some net sellers will be counting on their 03/31/98 TUE 18:23 FAX 202 647 5713 EB/FRONT OFFICE 004 THGE 3/4 allowance sales proceeds to cover monitoring costs and the cost of investments to further improve energy efficiency and emission performance. Performance bonds may be costly for the Parties that need them most. Insurance is not viable because the insured event is too much subject to the control of the insured Party and the Party may, in the short-run, gain more from default than from compliance. The insurance cost will be unfairly high for those who comply and too low for those who default. The issue is akin to the 1980 S&L problem. The problem is summarized by the suppose economic term "moral hazard" and creates incentives for a downward spiral toward progressive non-compliance and the parallel withdrawal of all insurers. Pure buyer liability: Under this option, buyers of allowances can use (tender) them for emissions compliance (i.e., receive the anticipated value) only to the extent that sellers retrospectively, meet their emission commitments. This is a bond market model. The determination of compliance d value is made long after some sales occur. Unless buyers can get effective guarantees of performance from the originator of purchased allowances or reliable assessments of risk, the buyer holds a very uncertain instrument. This risk, even in small doses, is unattractive to buyers and even less attractive to traders. Buyer liability for sellers' future emissions performance would likely be fatal to emissions trading, where, unlike the case of "full faith and credit" guarantees, when secure guarantees of performance across national boundaries are unlikely rost Modified buyer liability: If the FCCC Secretariat held the power to deny compliance tender value to allowances not supported by emissions compliance of the first issuer (a bond market model), DUE the direct compliance burden would fall on buyers, but an informed market could achieve substantial shifting of the compliance burden to sellers. For example, allowance trading could be conducted according to these rules: Traded allowances are identified as to original nationality and serially identified by date of their first recorded trade. For untraded allowances, the date of submission to the FCCC Secretariat for compliance determines the serial priority, to In the event of a Party's non-compliance, some allowances originating from that Party would be invalidated, starting from the latest dated allowances and proceeding backward, be of until the remaining quantity matched the Party's compliance achievements (i.e., domestic gaming the system emssions do not exceed retained allowances, and exchanged allowances do not exceed avoided emissions), Annual reports would reveal each Party's compliance progress (emissions) and AEU sales rate, thus permitting the market to assess how many allowances from each Party are likely to be valid, and a quality-adjusted price for each point in the serial sequence, Market prices for allowances would reflect expected probabilities of validity. Private tools, such as rating services, compliance consultants, derivative contracts, and portfolio syndications would arise to permit risk management strategies. Market information, both public and private, would permit shifting of risk exposure back to sellers through the market prices that informed buyers would offer for allowances of varying probable value. In the end, each allowance would be good or bad; all good allowances would have the same compliance value. Market information would permit a gradual sharpening, over the course of the budget period, of the price differential between expected good and bad allowances around the expected validity cut-point for cach Party.

Private steps in the trading process following emission assignment under the FCCC with modified buyer liability rules: Parties may, at their option, assign some allowances to sub-national entities. Holders may offer to sell allowances, to be identified by nationality and serially numbered in ascending order. Buyers offer prices, based on assessment of end-of-period compliance of seller. Highest prices will be offered for first issuances, which are the first to be honored within each nationality class. Later issuances carry greater risk of non-compliance bumping and will generally command lower prices. Rating agencies could offer assessments of the likely validity cut-off point for each issuer. Prices of allowances traded would reflect market consensus of future validity with continual adjustment of perceptions as compliance expectations change. Parties that show credible compliance reports will get higher prices for larger proportions of their sales offerings. Poor reports will limit the opportunity to sell allowances except at very low prices and for limited quantities. Speculators might enter to buy cheap allowances to rehabilitate them prior to the compliance date. At the end of the compliance period, FCCC Secretariat announces which allowances are valid. Nations make compliance tender of valid units and added compliance, as needed, to complete compliance. Supplemental compliance methods, like borrowing from the second budget or an agreed Liver "excess emissions fee" will be needed to permit national compliance in the event that who insufficient valid allowances remain to permit first period compliance. Official steps in the trading process under modified buyer liability rules: Emissions amounts assigned to Parties, Compliance authority agrees to permit allowance trading, Following any sale, the recording agent accepts joint order to record transfers; The recorder notes the nationality and places a serial number on newly-recorded allowances, and maintains the existing identifiers for previously traded allowances. At the end of the budget period, FCCC Secretariat announces which allowances are valid for compliance, based on the compliance showing of each issuer that traded. Parties supplement surviving allowances, if necessary, to complete compliance by borrowing, open market purchases, or pre-specified default payments. Prelim.

Emissions Trading Attachment Article 17 on Emissions Trading: What are the significant features? The penultimate draft said parties had the right to trade "once" rules were adopted; the final provision has a free-standing sentence containing the right to trade. While some countries had sought to put a percentage limit on the amount of a country's target that could be met through trading, the final provision says only that trading must be "supplemental" to domestic action (without giving the Parties the authority to quantify this term) Unlike other provisions, the Article refers to "Annex B" rather than "Annex I" Parties. This would allow developing countries, through an amendment to Annex B, to participate in emissions trading. Unlike other provisions, the body charged with developing the rules is the COP rather than the COP/MOP; this could allow earlier establishment of the rules. What is missing that was in earlier drafts? In order to engage in emissions trading, a Party has to be in compliance with its measurement and reporting obligations (now Articles 5 and 7), as well as have in place a national mechanism for the certification and verification of emissions trades. A Party may authorize intermediaries (which would have been understood to include the private sector) to participate in actions leading to the transfer or acquisition of tons. [Note: Even without such an explicit rule, we would interpret the Protocol not to preclude private sector participation.] With respect to any trading in which they engage, Parties were to submit annually to the Secretariat information regarding the quantity, Party of origin or destination, and the relevant budget period. -2- Emission levels achieved before the start of the first commitment period (so-called "superheated air") could not be used as the basis for emissions trading; such a provision is arguably no longer necessary in light of Article 3.10 and 3.11, which refers to transfers and acquisitions of "assigned amounts." A Party whose emissions were in excess of its allowed amount in any budget period could have acquired, but not transferred, tons. When a question was raised regarding a Party's compliance with its reporting/measurement obligations, transfers could continue to be made, but transferred tons could only be used to meet targets after the compliance issue had been resolved. 630916CW.WPD Page 1 THE SIMPLE STEPS OF AN EMISSION TRADE: Buyer and seller, having met the preconditions (budgets, monitoring, reporting), find themselves with compliance obligations that do not match their emission unit balances. Willing buyer and seller agree on a price and delivery date. Buyer checks that originator of the offered allowances (either seller or prior seller) was not on the public FCCC non-compliance list at the time the offered allowances were first sold. (If first seller is/was on the bad boy list, buyer may still buy, but with notice that allowance acquired will not be accepted for FCCC compliance until the seller's compliance deficiency is cured. Impaired allowances may be cheap and may be a good. value, depending what you know about the source and its prospects for compliance.) Seller determines that its anticipated emissions unit needs permit it to sell. Buyer pays the seller and seller delivers the allowances in a simultaneous transaction or through an escrow arrangement. Buyer may be a government in a G to G trade. Buyer may be a private firm buying from a government seller, buyer may be a firm buying frim a firm, or buyer may be a government buying from a private firm. In each case the required safeguards and authentications may vary. As money and allowances change hands, the FCCC records the transfer, debiting the seller's account and crediting the buyer. These same allowances could trade further before their use in emissions compliance. Interim trades may or may not be officially recorded, but the last ownership change before compliance use should be recorded. At the end of the agreed compliance period, buyer/owner of the allowance makes tender of allowances for its actual emissions. If the direct owner of the traded allowance is a Party, the allowance from trade may be submitted directly to the FCCC as part ofinternational compliance. If the owner is a firm, it makes a compliance tender to its national government (a Party). The Party then can use that same allowance that it collected in its national compliance process in tender to the FCCC as part of the international compliance process. As one of the enabling rules for trading, the international compliance process must explicitly state that all valid allowances are equal when tendered for compliance, regardless of their national origin.

These technological advances have been made possible through the efforts of the Partnership for a New Generation of Vehicles between the Administration and the U.S. auto companies and their suppliers.

Non-Climate Benefits A final factor that should be Included in any comprehensive assessment of the economic implications of the Kyoto protocol are the benefits of the agreement. The literature has emphaelzed that any relative price shifts that prove necessary to reduce emissions should produce non-climate benefits in three areas: air pollution unrelated to climate change, traffic congestion, and highway accidents. These benefits are hard to quantify precisely but are potentially significant> our rough setimates suggest that these three benefits could offer 16-25% of any keep resource 0001 of the elimate change policy.

Assuming that effective mechanisms for International trading, Joint Implementation and the Clean Development Mechanism are established, and assuming also that the U.S. achieves meaningful developing country participation. our overall assessment is that the economic cost to the United States in aggregate and to typical households of atteining the targets and timetables spealfied in the Kyoto Protocol, will be modest. This conclusion that the Impact will be modest is not entirely dependent upon, but la fully consistent with, formal model results. 1 have previously emphaeized the limitations of relying on any single modal in assessing the aconomic impact of the Kyoto Protocol, and continue to view any such results as Just one Input Into an overall analysis. But It is worth emphasizing that model results reflecting the details of the Kyoto Protocol are consistent with our conclusion.

Here are several specific comments and proposed changes. Most have these have been reviewed already with Randy Lutter, who found them acceptable. (We were Interrupted in discussing the last point, and need to talk again about that one.) P.15: In the paragraph on restructuring, change the fourth sentence to read: "In addition, stronger incontivos for Improved gonoration officiancy. in conjunction with provisions to conserve energy and promote use and development of renewable energy sources appropriate market based provisions, will could achieve modest reductions in emissions." Joh The change from "will" to "could" is needed to reflect the uncertainty regarding the emissions consequences of retail legislation - NEC and CEQ project is small (7-3%) decline (relative to approximately 40% baseline growth 1990-2010), and also acknowledge substantial uncertainty and that actual emissions could Increase. The phrase "appropriate market based provisions" was used In the October 22 fact sheet on restructuring to accompany the President's climate speech in order to bndge the gap between the DOE and EPA views on whether the renewables portfolio, atc. was sufficient to address emissions, or whether market based emissions provisions are needed as well. The P. 17: In the first paragraph on sinks, change the second to last sentence to read: "Very preliminary estimates indicate that carbon sinks could comprise up to nearly 10%'..."\ We have not reached a definitive policy decision on Interpretation of the Protocol's sinks language and are not yet In a position to Imply a "nearly 10%* bonus from sinks. The addition qualifies the point. oh! P.18: There is a typo in the first full pare: "25 percentage points" should read "0.25 percentage points." or "one quarter of one percent".

P. 9/24 Page 71 energy prices, which we will shortly address. In general it is difficult to undergo a structure) change in the economy without having the effect of expanding some sectors and contracting others. But to provide some perspective on this issue. consider the following facts. First, on average, energy constitutes only 2.2 percent of total costs to U.S. industry. Second, energy prices already vary significantly across countries. According to the 1997 Statistical Abstract, for example, in 1996 premium gasoline cost $1.28 per gallon in the United States - but only B cents per gallon in Venezuela. Similarly, gas prices were $3.71 per gallon in Switzerland and $4.41 per gallon in France. Electricity prices also vary significantly: in the U.S. they were 5 cents per kilowatt hour, a fraction of prices in Switzerland of 13 cents per kllowett hour. Yet U.S. industry is not moving on masse to Venezuela, nor is Swiss industry moving to the United States. Third, roughly two-thirds of all emissions are not in manufacturing at all, but In transportation and buildings. We therefore believe we need developing country participation because the problem is global and cost-effective solutions are essential, than to avoid adverse effects on oh compotitiveness. industries which by their nature would not Floxibility and Markul Mechanisms locale to other countries. A global solution Is thus critical to the global problem of climate change. Globalizing the solution la not, however, enough by itself. We must also ensure that our efforts to reduce global greenhouse ges emissions reductions in the most efficient manner possible. The nature of the climate change problem suggests three basic methods to lower costs of achieving given levels of environmental protection. They can be characterized in terms of three categories of flexibility: (1) "when" flexibility; (2) "what" flexibility: and (3) "where" flexibility, which may be the most important of all. Such methods have long been championed by aconomists Interested in increasing the efficiency of protection. Indeed, 2,600 economists from academia, industry, and government alike urged such approaches In a letter they signed last year advocating action on climate change: "Economic studies have found that there are many potential policies to reduce greanhouse gee emissions for which the total benefits outweigh the total costs... The most efficient approach to slowing climate change is through market-besed policies." 1. "When flexibility" (timing) First is "when flexibility or timing. Since climate change is a long-term problem, the exact timing of emissions reductions is, within some range, not of primary importance. Thus the freadom to delay or accelerata reductions within on agreed upon time frame -- while ensuring credibility of emissions reductions -- lowers costs. As a result of U.S. leadership, the Kyoto Protocol incorporates this ID: MAR 02'98 17:27 No 004 P.07 FEB-27-1998 16:15 TO:51 - JUSTICE FROM: FITTER, E. P. 11/24 Page greenhouse gases by a greater percent than reductions of CO2 could reduce prices by as much as 10 percent. Thus allowing countries flexibility in what gases they reduce - essentially trading emissions reductions across gases - can help lower significantly the costs of meeting their targets. The second source of "what flexibility" is the treatment of sinks, i.a., land use activities that promote the removal of curbon from the atmosphere through the growth of plants. At the urging of the U.S. delegation, sinks can be used to offset emissions turgets. Promoting such sinks through afforestation and reforestation may reduce stmospheric concentrations of CO2 at much lower costs than reducing emissions of greenhouse gases. 3. "Where flexibility" (international) The third type of flexibility, and perhaps the most important. is "where flaxibility" (International). As I have already emphasized, emissions have the same environmental consequences regardiess of where in the world they occur. Therefore, the least-cost approach to controlling climate change is to reduce emissions wherever such reductions are cheapest. The Kyoto Protocol, because of U.S. Insistance and persistence, includes three Important cost-saving pravisions of this nature. no First, It provides for countries that take on binding targets, at present the Industrial countries, to trade rights to emit greenhouse gases with each other. This market In emissions permits could ensure that emissions reductions occur where they are least expensive within the Industrial countries. In particular. U.S. companies could purchase omissions that reductions In other participating countries when doing 90 would reduce their costs -- thus lowering COSTS without affecting the leval of we that an environmental protection. Second, the agreement provides for joint Implementation by Annox 1 countries. Thus If some Industrial countries do not develop programs to can trade permits Internationally, U.S. firms could nonetheless Implement projects in those countries for which they could receive emissions reductions credits In the U.S. Third, the agreement allows Industrial countries to invest in "clean development" projects In the developing world and use these projects' certified emissions reductions toward meeting their targets, Many such clean development projects may be quite cheap In terms of the cost per ton of emissions avoided, 88 has been illustrated by the joint Implementation pilot program that is already in place in the U.S. RRRC DTS 202 PAY OT:BI NON 03/20/83 ID: MAR 02'98 17:28 No. 004 P.08 FROM:FITTER, E. r. 11/19 FEB-27-1998 16:24 TO:114 - STATE LRM ID: EHF385 SUBJECT: Council of Economic Advisors Oversight Testimony on KyDio Climate Treaty RESPONSE TO LEGISLATIVE REFERRAL MEMORANDUM If your response to this request for views is short (a.g., concin/no comment), we prafer that you respond by e-mail or by faxing us this response sheet.

Economic and Monetery Damages The derivation of quantitative or monetary estimates of the damages from such a change in the climate in extremely difficult given the capacity of today's models. Estimates of the economic damages from climate change fall Into the following broad areas: agriculture. sea-level rise. air conditioning and heating, water supply, human life and health, air pollution, and other costs thurricanes, relocation costs. human ementty, construction, leleure activities, urban infrastructure, and ecological damages such 88 forest loss and species loss). Although the quantification of these effects 18 quite demanding, researchers have developed estimates that prompt substantial concern. The IPCC reports that 8 doubling of carbon dioxide levels would lead to about 6,000 to 10,000 additional deaths per year from higher summer temperatures, even after netting out the attents of warmer winters and assuming acclimatization. Other researchers have predicted sea level Increases of about 20 inches by 2100, with substantially greater increases in subsequent years. Despita the difficulties, respected researchers have developed estimates of the monetary damages expected from an average worldwide temperature Increase. For example, Cline estimated that a temperature change of 4.6 degrees Fahrenheit would Impose ennual damages of more than $70 billion per year on the U.S. economy in today's farms, These damages Include 422 billion in lost agricultural production, #13 billion in additional electricity costs, and $8 billion in new costs to maintain the existing supply of fresh water. (Cline's original estimates are quoted in 1990 dollars. The figures given above translated those numbers Into 1997 dollars using the annual GDP price Index.) William Nordhaus of Yale University has likewise computed estimates of the dollar loss attributable to - doubling of greenhouse gas concentrations. Although he USBS methods that differ from Cline's in several respects, he finds that the Cline estimate is In the center of three estimates for the U.B., and that the high estimate is only 30 parcent greater then the low estimate, It must be noted, lowever, that this similarity among aggregate estimates masks the true uncertainty associated with forecasta of the damages from given Increases in global warming - the estimates are all fundamentally based on extrapolations from current and past experience, and may not fully incorporate effects that will unfortunately become apparent only with future experience. One key difficulty In Interpreting and monetizing these estimates of damages is uncertainty over the extent that they should be discounted because they coour in the dietant future. Since the benafits of stemming future climate New scientific information Notal in various scientific no journals iN 1957 indicates that transperature increases from a doubling If CO2 may be below the low end of the 1955 IPCL range, e.g. below 1.5 defrees C. If this is so, the health effects and the economic imports are likely to be overstated. ID: MAR 02'98 17:31 No 004 P.14 Details of how these provisions will operate will be discussed In future negotiations such as the one in Buenos Aires later this year. Nonetheless, effective international trading of emission credits. joint Implementation, and the Clean Development Machanism can lead to substantial reductions in costs relative to alternative policies that do not exploit the power of market incentives. To illustrate briefly the ability of U.S. Industry to perform beyond expentations when given appropriate oconomic incentives, consider further EPA's highly accleimed sulfur dioxide (802) program, which relies, among other things, on a system of tradeable permits to reduce emissions of 602 from electric utilities. The SO2 program has been successful in several ways: B large number of utilities participate, 802 emissions and amblent concentrations have fallen and the costs of reducing emissions are considerably lower than originally forecest. As has been frequently noted, the average cost of 302 emissions reductions has recently been significantly lower than WSB originally forecast, in part due to the role of insentives in fostering Innovation. Emission permit prices, currently at approximately $100 per ton of 902, are well below earlier estimates of around 6250 to $350 por ton. Trading programs may not always bring cost savings as large as those achieved by the 502 program: trading programs will not always be accompanied by the discovery of much cheaper control strategies) However, the 902 experience demonstrates clearly how programs like international permit trading, joint implementation. and the Cleen Development Mechanism will lead firms to find cheeper ways of reducing emissions that can lead to unexpectedly low costs. IV. Difficulties of Economic Analysis of the Kyoto Protocol Now that we have a Protocol even If It is not yet fully complete nor ready for the President's submission to the Senate It is possible to examine It in somewhat more detail from an aconomic perspective. But, once again the inherent limitations of any such estimates deserve emphasis. Such limitations should not be surpricing to you: economists have a difficult enough time projecting the behavior of the economy over the next quarter or year, let alone over the next two decades. The scale of the forecesting exercise is therefore deunting, and any specific results should be treated with substantial oaution. The difficulties associated with economic analysis of plimate change fall into three broad antegories. First are the uncertainties that still remain over the terms of the ultimate treaty, necessitating assumptions on which the analysis is predicated. Second are the Inherent limitations of available models to analyze even short-term costs and benefits. And finally Is a topic discussed earlier: the impossibility of putting a single monetary number on the lang-term benefits of climate change mitigation, although there will olearly be economic benefits of It also should be noted that a worldwide program of greenhouse gas emissions trading is substantially more complex thom the trading of ONE pollutment iar one country. Furtharmore, monsitaring and verification are important elements to be addressed before successful adoptions of this program. ID: MAR 02'98 17:32 No. 004 P.15 Page emission reductions. Uncertainties in the International Effort to Combet Climate Change The Kyoto Protocol WBS an historic sonomplishment, delinesting the broad terms of the International effort to address climate change. But although we know a lot more than we did before Kyoto about how that International system will work, and that informa our analysis, there is still much that we do not know. First, some provisions raise complex implementation issues. At issue here is the treatment of so-palled sinke - activities that affect the rate at which carbon is removed from the atmosphere and "sequestered," c.g., by the planting of trues. development mechanisms clean Second. the details of a number of Items - primarily concerning International trading/end developing countries " are the subject of further discussions Including future negotiations in Buenos Aires next fall, because they had not been definitively settled by the end of the last all-night session of the Kyoto talks. Finally, and most importantly, we have not yet negotiated international agreements to limit amissions beyond the 2012 window. The emission cuts agreed upon at Kyoto are only a first step on a long journey. The first step that We propose to take over the next 15 years is critical. But the reason It is critical is not that, by itself, it will solve the climate change problem -- emissions during any given decede are email compared to the cumulative concentrations in the atmosphere. Rather, the first step is critical because We oan not take the second and third steps until we have taken the first. At the same time. any analysis is complicated by the lack of knowledge over what the subsequent steps will be. inherent Limitations of Models in addition to these uncertainties about the details of the international effort to address climate change, are the Inherent limitations of the models used to evaluate that effort. Even within a given model, answers depend oritically on the precise nature of the question asked. For example, the costs of emissions reductions depend critically on the extent of global perticipation and International trading that a treaty is assumed to feature. But in addition to the depandence of the results from a given model on the preoisé assumptions, different models can give different answers even when all the assumptions are specified to be the same - a concrete Illustration of the range of undertainty to which wo must essign the preditions of any one Individual model. One aree in which the uncertainty is particularly large is the pace of technological progress ---aspecially the diffusion of existing energy-efficient ID: MAR 02'98 17:32 No 004 P.16 Page 121 technologies, but also the development of new technologies and the extent to which the pace will accelerate in response to government programs. Models and experts on climate change policy tend to have a wider range of dissgreement on the scope for speeding the diffusion of existing energy-efficient technologies than on any other single Issue. Furthermore, each model has strengths and weaknesses; each has questions to which it is batter or worse sulted 10 answer. Some. for example, model the energy sector In detail. Some allow for the fact that a coal-fired power plant cannot costlessly be converted to one that runs on natural gass, Some show the effects of hypothetical tax outs made possible by the new revenues earned through the auction of emissions pomite. Some are capable of showing recessions and booms. Others include a long-term "carbon cycle" model that can keep track of the accumulation of greenhouse gas concentrations In the atmosphere and their alimatological effects. Some break down the rest of the world Into regions and so can model International trade. No one model does everything, and therefore we must not rely bilndly on the resulte of any one model or set. of modela. Professional judgement and economic intultion, along with diplomatic assessments, are also orucist. Benefits of Averting Climate Change As disoussed above, it is evident that the benefits of averting climate change are potentially Immense. But we have chosen not to try to quantify them in monetery terms, in light of the difficultles we have anumarated. These Include the undertainty of these benefits, their timing and therefore the extreme sensitivity of the results to the chosen discount rate. and the dependence of benefits on emissions paths after the 2008 to 2012 budget period specified in Kvoto. V. Asssssing the Kyoto Proteool In order to evaluate the likely net economic Impact of the Kyoto Protocol, excluding the benefits of mitigating climate change Itself, we have drawn upon a variety of tools to assess the various possible costs and non-climate benefits of the Administration's emissions reduction pollcy, To give away the punch line, our conclusion is as follows: the net costs of pur policies to reduce emissions are likely to be small, assuming those reductions are undertaken In an efficient menner and we are successful in securing meaningful developing country participation as well as effective International trading and clean development mechanisms In future negotiations. That potential small net premium, oven excluding the benefits of mitigating climate change, in effect, purchases # partial Insurance policy against a aerious environmental threet. Because the reaults from any model must be treated with oaution, the assumptions that will magnina much effort to realize. No ID: MAR 02'98 17:33 No. 004 P.17 I said in Congressional testimony last July that we can do this smart or we can do this dumb. 1 was referring to the point that the costs of outting emissions can be much reduced if flexible, market-based mechanisms are used. Our economic analysis highlighted the importance of such flexible, market-based mechanisms - which are therefore reflected, at the President's insistence, in the /on Kyoto Protocol and our ongoing diplomatic strategy. clean development mechaw ism Within the Kyoto Protocol, this means an Insistance on international trading implementation and, lultimately. on meaningful developing country participation-Dornsstiealy, this means that we Implement any emissions reductions through a market-baced system of tradeable emissions pennits, which ensures that we achieve reductions wherever they are least expensive. But this also means taking serious and responsible steps in the short run to prepare us to meet our obligations in the longer term. The first such step Is the inclusion in this year's budget of an aggressive, $6.3 billion program of tax outs and R&D investments - $1.3 billion more than the $5 billian package the Prexident promised in his Outober 22 speech on this Issue. The goal is both to stimulate the development of new energy-saving and cerbon-saving technologies and to encourage the dissemination of those that exist already. The proposed package contains $3.6 billion over the next 5 years in tax DULE for energy efficient purchases and renewable energy. Including tex credits of $3,000 to $4,000 for consumers who purchase highly fuel efficient vehicles, a 15 percent credit (up to $2,000) for purchases of rooftop solar equipment, a 20 persent credit (subjent to . cap) for purchasing onergy-efficient building equipment, a oredit up to $2,000 for purchasing energy-sfficient new homes, an extension of the wind and blamass tex credit, and a 10 persent Investment credit for the purchase of combined heat and power systems. The package also contains #2.7 billion over the next 5 years in additional research and development investments covering the four major carbon-emitting sectors of the economy thulidings, Industry, transportation, and electricity), plus carbon removal and sequestration, Federal facilities, and cross-cutting analyses and research. One example of the R&D effort le the Partnership for a New Generation of Vahicles (PNGV).

The umbrella could, for example greatly reduce costs to the U.S. Results that we have derived from various 6GM simulations of officient International trading suggest that, relative to the situation in which there is no trading at all, the umbrella can reduce costs by an estimated 60-75 percent, depending on whether the former Warsaw Papt countries fall within the umbrella. The Kyoto Protocol classifies these countries outside of the EU bubble for the first budget period 2008-2012. Estimated reduction In costs from developing country participation The next consideration is participation by developing countries. The President has said that he will not submit the treaty for ratification without meaningful participation by key developing countries. Such partisipation would further reduce the costs Involved. The substantial potential gaine from maaningful developing country participation are highlighted by the significant benefits that will likely accrue even from the limited rale that the developing countries have already agreed to: the Clean Development Mechanism (CDM), medeled after the U.S. joint implementation heep concept The CDM cannot realistically be expected to yield all the geins of binding targets for developing countries, but it might shave costs by roughly another 20 to no 25 percent from the reduced DOBIS that result from trading among Annex 1 countries. Another possibility is that we persuade como of the key developing countries that are the lergest emittere to commit to targets, and allow us to buy keep excission reductions from those paths. Simulations with the 8GM model suggest that full participation by non Annex 1 countries could cut roughly 55 percent off the reduced costs that result from Annex 1 trading, The actual cost reduction would no depend on the extent of developing country partiolpation that la ultimately obtained, as woll OP the effectiveness of international trading arrangements. The more developing countries that take on modest binding targets and trade in international ID: MAR 02'98 17:34 No 004 P.19 pollution emissions by 90 percent. These technological advances have been made possible through the afforts of tho Partnership for a New Generation of Vehicles between the Administration and the U.S. auto companies and their suppliers. Such progress may be replicated in other sectors. VCRs and TVs, even when off, consume about $1 billion worth of electricity annually. EPA has astablished a partnership with major manufacturers that has a goal of achieving . 70% reduction In energy use, without secrificing product quality, usefulness, of increasing costs, This partnership offers pramico of substantial improvements In energy efficiency. Non-Climate Benefits A final factor that should be Included in any comprehensive assessment of the economic implications of the Kyoto protocol are the benefits of the agreement. The literature has emphaelzod that any relative price shifts that prove necessary to reduce emissions should produce non-climate benefits In three areas: air pollution unrelated 10 climate change, traffic congestion, and highway accidents. These benefits are hard to quantify precisely but are potentially significant> our rough setimates suggest that these three benefits could offert 16-25% of any keep resource 0001 of the elimate change policy. Sugget deleting it Synthesis can be verivied by specific modeling results as described in other parts of must integrate all of the factors described above: reliance on flexible market-based the A comprehensive evaluation of the economic Impact of the Kyoto Protocol mechanisms domestically; International trading and Joint Implementation among testimony. Annex 1 countries; the Clean Development Mechanism; maaningful developing country participation; the potential cost-mitigeting role of including six gases and carbon sinks: the benefits of electricity restructuring) and emissions reductions achieved as a consequence of other proposed Administration climate change initiativos. Assuming that effective mechanisms for International trading, Joint Implementation and the Clean Development Mechanism are established, and assuming also that the U.S. achieves meaningful developing country participation. our overall assessment is that the economic cost to the United States In aggregate and to typical households of atteining the targets and timetables spealfied in the Kvoto Protocol, will be modest. This conclusion that the Impact will be modest la not entirely dependent upon, but la fully consistent with, formal model results. 1 have previously emphasized the limitations of relying on any single modal in assessing the economic impact of the Kyoto Protocol, and continue to view any such results as just one Input Into an overall analysis. But It is worth emphasizing that model results reflecting the details of the Kyoto Protocol Are consistent with our conclusion. For
