The report examines the economic and environmental impacts of carbon pricing on industrial competitiveness and the risk of carbon leakage, where emissions shift to jurisdictions with less stringent policies. It analyzes six policy options—border taxes, mandatory allowance purchases, embedded carbon product standards, aid to industry, free allowances, and sectoral approaches—concluding that while border carbon adjustments (BCAs) are theoretically more effective at reducing leakage in specific sectors, they face significant technical, administrative, and WTO legal challenges. The document emphasizes that only a small fraction of GDP (typically less than 1%) is truly at risk, primarily in energy-intensive, trade-exposed sectors like cement, steel, and aluminum.

The report argues that stabilizing atmospheric CO2 at 350 ppm is economically feasible, with estimated costs ranging from 1% to 3% of global GDP per year. It challenges 'go slow' economic recommendations, specifically critiquing the DICE model's default assumptions, and suggests that the costs of inaction far outweigh the costs of rapid mitigation. The authors emphasize that achieving this target requires a comprehensive global transition to carbon-free energy and the implementation of negative emissions technologies, such as large-scale reforestation and biomass energy with carbon capture and storage (CCS).

The report analyzes carbon leakage, which occurs when production shifts from regions with high carbon prices to those with lower or no prices, undermining climate policy effectiveness. It examines the EU ETS as a frontrunner and compares it with emerging systems in the US and Japan. The document evaluates mitigation strategies, including free allowance allocation, investment subsidies, and border adjustment measures (BAMs). It specifically analyzes the leakage potential of energy-intensive sectors like cement, steel, and aluminium, and discusses the legal and multilateral challenges of implementing border adjustments under WTO rules.

The Climate Strategies Research Prospectus 2009 details a comprehensive program of academic research designed to support government decision-makers. The work is organized into three primary themes: industrialised country commitments and global market mechanisms (including carbon leakage and emissions trading system linkages), global engagement, technology and finance (focusing on the UNFCCC's Reformed Financial Mechanism and technology innovation centres), and industry-specific sectoral approaches (specifically the steel and maritime sectors). The organization operates as a not-for-profit network, convening international experts to provide independent, fact-based assessments for policy formation, with a particular emphasis on the European Union, North America, and the Asia-Pacific region.

The paper finds that integrating REDD into global carbon markets significantly reduces tropical deforestation emissions and lowers overall climate policy costs by 10-25%. While it slightly decreases investments in some renewable energy and nuclear R&D (by 1-10%), it may marginally increase investments in carbon capture and storage (CCS) and integrated gasification combined cycle (IGCC) technologies. The study highlights that 'banking' credits enhances these cost savings and provides policy flexibility for future more stringent targets.

The study compares different market instruments for CO2 mitigation in Spain, finding that cost-effectiveness depends heavily on the scope of the instrument and the specific sectors or fuels targeted. Using an AGE model, the author demonstrates that a 'complete market' for emission permits or a direct CO2 tax are the most cost-effective options. In contrast, narrow instruments—such as a tax on electricity or a permit market excluding energy-intensive industries—significantly increase the cost of achieving emission reductions in terms of GDP and utility loss. The results indicate that as CO2 reduction targets increase, the costs rise disproportionately, with some inefficient instruments costing up to 13 times more than the cost-effective benchmark.

The Climate 2030 Blueprint proposes a combination of an economywide cap-and-trade program and complementary sector-specific policies to reduce U.S. greenhouse gas emissions. The analysis argues that these measures can achieve deep carbon cuts while generating significant net savings for consumers and businesses, reducing oil dependence, and maintaining robust economic growth.

The paper investigates the potential of CER discounting to address CDM shortcomings, such as non-additionality and the uneven distribution of projects. By analyzing abatement cost curves for China, India, advanced Asian countries, and LDCs, the authors find that while discounting can increase costs for advanced developing countries and potentially incentivize them to adopt their own mitigation commitments, it is insufficient on its own to make LDCs competitive. The study concludes that financial, technical, and institutional barriers in LDCs must be overcome for them to realize their theoretical abatement potential, as the abundance of cheap projects in countries like China continues to dominate the market.

The document analyzes the role of carbon markets in financing climate action in developing countries, estimating potential revenues and evaluating different market mechanisms. It argues that while the Clean Development Mechanism (CDM) has provided a starting point, expanding to sectoral and allocation-based mechanisms is necessary to cover the high-emitting electricity and industrial sectors of Major Developing Economies (MDEs). The paper proposes a phased approach to developing country participation, moving from broadened CDM and other market mechanisms for sustainable development (MMSDs) toward sectoral and economy-wide commitments, contingent on developed countries meeting their own stringent targets.

The 'Economics of Climate Change – Towards a Low-carbon Economy in China' project, running from October 2007 to November 2009, sought to shift the Chinese government's perspective on climate change from a cost-based reactive position to an opportunity-driven one. Through a collaboration between Chinese and international economists, the project produced 13 action-oriented background papers and a synthesis report to explore alternative low-carbon development paths and international cooperation mechanisms.

The report argues that RGGI's design, which caps emissions only for power plants within participating states, creates a price advantage for imported electricity from coal-heavy states like West Virginia and Pennsylvania. This 'leakage' is exacerbated by excess capacity in existing coal plants and planned transmission upgrades that facilitate power flow from west to east. The authors suggest that RGGI states should implement retail-level carbon caps, prohibit contracts with high-emission plants, and prioritize transmission projects aligned with climate goals to prevent the expansion of coal-based power.

The document analyzes the Indian steel industry's high carbon intensity, driven by a proliferation of inefficient small-scale coal-based direct reduced iron (DRI) units and small blast furnaces. It argues that current project-based mechanisms like the Clean Development Mechanism (CDM) are insufficient for systemic change. The author proposes a combination of a harmonised carbon tax and administered manufacturing standards to incentivize a shift toward larger, more efficient blast furnace-basic oxygen furnace (BF-BOF) units and the long-term substitution of steel with low-carbon materials. The paper emphasizes that international cooperation in technology transfer and capacity building is essential to support these domestic policy shifts.

The document argues that REDD is a cost-effective method for reducing heat-trapping emissions, noting that $5 billion annually could protect nearly 20% of tropical forests at risk, while $20 billion could protect about half. It identifies opportunity costs as the largest expense and highlights that global models provide more conservative, comprehensive cost estimates than regional studies. Total implementation, administrative, and transaction costs are estimated at nearly $1 per ton of reductions, with separate stabilization costs estimated at $630 million per year for the ten most critical countries to prevent international leakage.

The paper argues that the EU cement sector is more exposed to carbon leakage than generally assumed, particularly in coastal regions. Using two models with a CO2 price of 30 €/t, the author finds that short-term import levels in coastal regions would rise from 13% to 25%, with an overall EU leakage rate of 65%. In the long term, EU cement capacity is projected to decline by 13% as imports become more attractive during peak demand. The author concludes that while output-based allocation might mitigate financial pressure, a severe world recession would likely induce a similar industrial restructuring to that of a full auctioning scheme.

The document analyzes the impact of climate policy uncertainty on investment decisions, highlighting how different actors—such as oil majors, utilities, technology developers, and banks—respond to CO2 price volatility and regulatory ambiguity. It explores various economic appraisal methods, including real options and risk premiums, to demonstrate how uncertainty can delay investments or bias them toward fossil fuels. The author argues that while governments value policy flexibility, stronger commitments and intermediary targets are necessary to provide the credibility required for private sector investment in low-carbon technologies.

The report assesses how the EU ETS affects industrial competitiveness, identifying that while most sectors can profit in the short term through free allowances and cost pass-through, a small number of carbon-intensive subsectors face significant risks. Using UK and German data, the authors develop 'Value at Stake' indicators to screen for exposed activities. The analysis concludes that leakage concerns are concentrated in a few subsectors, particularly cement and blast furnace steel, where high direct emissions and international tradeability create vulnerability. The report argues that free allocation can mitigate these risks but may create perverse incentives, suggesting that targeted policies or harmonized allocation across EU Member States are necessary to maintain economic performance while achieving emission reductions.

The document asserts that new conventional coal plants are imprudent investments due to the certainty of future U.S. federal CO2 regulations, likely in the form of a cap-and-trade system. It argues that such regulations will significantly raise the cost of coal-fired electricity, making energy efficiency and renewables more competitive. The report urges state regulators to protect ratepayers by either denying the construction of new coal plants or requiring that shareholders, rather than customers, bear the financial risk of future carbon compliance costs.

The report identifies six loopholes—three regulatory and three tax/policy-based—that have contributed to a decline in U.S. fleet fuel economy from a 1987 peak of nearly 26 mpg to 24.4 mpg by 2004. These include the misclassification of passenger vehicles as 'non-passenger' to meet lower standards, the total exemption of vehicles over 8,500 lbs GVWR, and inflated credits for dual-fuel vehicles that rarely use alternative fuels. It also highlights tax incentives for luxury SUVs and the exclusion of light trucks from the 'gas guzzler' tax. The authors argue that closing these loopholes could reduce U.S. oil dependence by 1.5 million barrels per day by 2025 and save consumers $33 billion.

The report examines the shift of tax burdens from labour to consumption and natural resource use, known as Ecological Tax Reform (ETR). It analyzes how EU nations have used energy, transport, and pollution taxes to internalize environmental costs while maintaining economic competitiveness. The document highlights that successful ETRs often combine tax increases on pollutants with reductions in social security or income taxes, creating a 'double dividend' of environmental improvement and increased employment. Based on these international experiences, the report suggests that Estonia should phase out subsidies for its oil-shale energy sector, introduce carbon-based energy taxes, and implement differentiated vehicle taxes to stimulate resource efficiency and sustainable development.

The document consists of several appendices. Appendix A lists Class I areas not evaluated by the EPA. Appendix B compares SO2 and NOx reductions under CAIR versus the Best Available Retrofit Technology (BART) standard. Appendix C is a detailed scientific critique of the ARIES study, arguing that utility industry claims using ARIES to downplay the health risks of sulfates are not supported by the study's actual data or broader medical literature. Appendix D lists counties remaining in nonattainment for PM2.5 and ozone. Appendix E contains a statement from the Institute of Clean Air Companies on the achievability of NOx and SO2 limits. Appendices F through L provide detailed modeling data, cost summaries, and emission projections for various policy scenarios (CATF11, 18, 19, 21, 22, 23).
