The report argues that carbon trading is a fundamentally flawed mechanism that fails to drive real emissions reductions or technological innovation, instead creating risks of financial speculation and locking economies into high-carbon infrastructure. It specifically critiques the use of offsetting as an unjust 'escape hatch' that shifts responsibility from developed to developing nations. The authors advocate for a shift toward direct government interventions, including carbon taxation, strict regulation, and massive public investment in low-carbon infrastructure, while calling for developed countries to provide at least €200 billion per year in new and additional climate finance to the global South.

The document argues that carbon trading is an ineffective and dangerous approach to climate mitigation, failing to drive necessary emissions cuts or technological innovation. It highlights six central problems: inefficiency in driving reductions, failure to stimulate innovation, lock-in of high-carbon infrastructure, reliance on flawed offsetting, the risk of a financial bubble similar to the subprime mortgage crisis, and its use as a smokescreen for the developed world's failure to provide climate finance. The report recommends halting the global expansion of emissions trading and instead deploying direct tools such as carbon taxes, regulation, and public investment. It further calls for developed countries to reduce emissions by at least 40% by 2020 (excluding offsets) and provide at least 200 billion in annual public funds to developing countries by 2012.

The report argues that China can achieve a deep carbon reduction by 2050 through sectoral transformations in electricity, industry, transport, and buildings, provided it receives international financial and technological support. It proposes a combination of domestic carbon taxes, a future cap-and-trade system, and a new 'Inter-country Joint Mitigation Plan' to facilitate technology transfer. The analysis emphasizes that a low-carbon transition is essential for China's modernization, offering opportunities to move up the value chain and improve energy security, though it will require active labour market policies to manage job losses in heavy industry.

In a speech delivered at a conference in Pretoria, Deputy Ambassador Søren Asp Mikkelsen discusses the necessity of a new international climate regime to replace the Kyoto Protocol, emphasizing the need for inclusive emission reductions and financial support for least developed countries. He highlights the 'Danish Wind Case' to demonstrate how legislative changes—such as feed-in tariffs and carbon taxes—can decouple economic growth from energy consumption and create a competitive export industry in renewable technology.

The document provides a comprehensive review of various Integrated Impact Assessment Models (IAMs), categorizing them into fully integrated, non-CGE, and CGE-type models. It specifically examines the 'damage functions' used to translate temperature increases into economic losses, noting a high degree of subjectivity and uncertainty in these calculations due to a lack of empirical data.

The document examines climate change as a global challenge characterized by scientific uncertainty and long-term impacts. It frames the issue as a 'market failure' resulting from negative externalities, where the costs of greenhouse gas emissions are not internalized. The authors discuss the economic costs of mitigation versus inaction, the ethical implications of discount rates and inter-generational equity, and the potential for 'carbon leakage' in international trade. It emphasizes the necessity of combining mitigation and adaptation strategies, the critical role of R&D and technology transfer to developing nations, and the importance of international agreements like the Kyoto Protocol and the 2009 Copenhagen Summit (CoP 15).

The report examines carbon leakage risks for energy-intensive industries—specifically cement, steel, and aluminium—when facing unequal global carbon prices. It evaluates tools such as free allocation of emission rights and border adjustments, noting that while free allowances can reduce leakage, they may distort carbon price signals and reduce incentives for low-carbon investment. The analysis suggests that border adjustments are particularly suitable for the cement sector due to the homogeneity of production technologies and carbon intensity across regions.

The document examines border carbon adjustments (BCAs) as a tool for OECD countries to protect domestic industries from 'unregulated' foreign competition and prevent carbon leakage. It identifies trade-exposed energy-intensive sectors—such as iron, steel, and chemicals—as the most vulnerable. The analysis highlights significant WTO legal hurdles, including national treatment and most-favoured-nation obligations, and suggests that any legal BCA would likely require a firm-by-firm carbon footprint calculation and prior attempts at multilateral agreement. Administratively, the author notes the difficulty of establishing a common metric to compare diverse climate policies and the risk of 'punishing domestic manufacturers' if only basic raw materials are covered. Geopolitically, the document argues that BCAs may conflict with the UNFCCC principle of 'common but differentiated responsibility' and could provoke 'vitriolic' reactions from developing countries, potentially hindering international climate negotiations.

The document argues that South Africa's international credibility in climate negotiations is undermined by a domestic reliance on fossil fuels and a slow integration of climate considerations into economic policy. Using Robert Putnam's 'two-level game' framework, it highlights the tension between Level I (international negotiations) and Level II (domestic interests), particularly the influence of the coal and oil industries. While South Africa champions developing nations' interests globally, its domestic energy strategy continues to favour coal-fired power and coal-to-liquids technology. The paper suggests that the Southern African Development Community (SADC) region offers untapped renewable energy potential that could help reconcile these competing imperatives.

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 document examines the critical role of regional governments in implementing climate change mitigation and adaptation policies, noting that while national governments negotiate international targets, regions often hold the actual competencies for execution. It analyzes 23 regions, highlighting a variety of instruments such as carbon taxes, subsidies, and cap-and-trade systems. A detailed case study of the Basque Country's 'Basque Plan to Combat Climate Change 2008-2012' illustrates how a small, industrialised region can set specific targets for GHG emissions and carbon sinks while coordinating across multiple policy sectors.

The paper argues that climate change is a global public bad requiring coordinated public-sector intervention. It posits that 'knowledge communities'—groups of experts who produce and share scientific information—are essential for driving the paradigm shifts and technological adoption needed for mitigation. The Intergovernmental Panel on Climate Change (IPCC) is highlighted as a primary catalyst for this global learning process. The authors also analyze economic instruments for emission reduction, such as the EU Emissions Trading System (ETS), taxes, and standards, while noting the difficulties of international cooperation under frameworks like the Kyoto Protocol.

The document defines carbon pricing as a market-based strategy to internalize the costs of climate impacts, driving a shift toward a clean energy economy. It details two primary mechanisms: cap-and-trade, which limits total emissions through tradable allowances, and carbon taxes, which set a fixed fee per ton of carbon. The text emphasizes that while both can effectively reduce emissions, they require complementary policies and careful design to address equity concerns, such as the regressive impact on low-income households and the economic transition for fossil-fuel-dependent communities. It highlights existing examples like the EU-ETS and RGGI, and suggests that revenues from these programs can be used for rebates, clean energy investment, or deficit reduction.

The policy brief examines the trade-off between free allowance allocation and border adjustments in emission trading schemes. It argues that while free allowances protect against carbon leakage, they undermine the effectiveness of carbon pricing. The author proposes that combining full auctioning with border adjustments—strictly limited to carbon-intensive commodities and based on the carbon intensity of best available technology—can address leakage. However, to avoid WTO violations and suspicions of protectionism from developing countries, these measures must be pursued through international cooperation rather than unilaterally.

The report analyzes energy-related greenhouse gas (GHG) mitigation potentials for six major developing countries through 2030. It projects that baseline energy-sector emissions for these nations could double to approximately 17 metric gigatons of CO2 equivalent by 2030, representing over 40% of global energy-related GHG emissions. The study identifies high-potential mitigation options across four sectors: electricity production, transportation, buildings and appliances, and industry. Common high-potential strategies across all six countries include renewable energy development, vehicle efficiency standards, and the enforcement of building and appliance energy codes. The report emphasizes that while many low-cost options exist, significant barriers remain, including high up-front capital costs, limited technical capacity, and the need for international technology transfer.

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 document argues that capturing biogas—primarily methane—from organic waste sources is a cost-effective method to mitigate climate change and displace fossil fuels. It details the technical and economic viability of landfill gas (LFG) projects, wastewater treatment anaerobic digestion, and agricultural manure digesters, while identifying policy barriers such as high capital costs and grid interconnection issues.

The report assesses government support for liquid biofuels in Canada, finding that total transfers between 2006 and 2008 ranged from C$860 million to C$1.02 billion. It argues that these subsidies are an expensive way to reduce greenhouse gas emissions and conserve fossil fuels, often providing poor value for money compared to purchasing carbon offsets. While Canada has implemented some effective targeting and caps to limit costs, the report highlights poor transparency, a lack of rigorous environmental evaluation, and the potential for future infrastructure costs driven by blending mandates.

The document analyzes the 'boom and bust' pattern of carbon prices in emissions trading schemes, attributing it to fixed supply facing highly uncertain demand and asymmetric information. It argues that price collapses undermine low-carbon investment and economic efficiency. While rejecting carbon taxation as a viable alternative due to political and implementation hurdles, the author proposes several policy options to stabilize markets, highlighting reserve price auctions in the EU ETS as a feasible, low-complexity mechanism to reduce supply automatically if prices fall too low.

The document analyzes the landscape of emissions trading schemes (ETS) in North America, noting that while regional initiatives like the Western Climate Initiative (WCI) and Regional Greenhouse Gas Initiative (RGGI) are advanced, national efforts in the US and Canada face coordination challenges. It argues that linking is logical due to economic ties, but current designs—particularly Canada's intensity-based targets—create barriers to bilateral links with absolute-cap schemes. The author concludes that a US federal scheme would likely preempt most state schemes, while Canada may use equivalency agreements to allow provincial schemes to persist.
