The document examines how unilateral carbon pricing creates production cost variations that may lead to 'carbon leakage'—the relocation of production to regions with less stringent environmental standards. It analyzes policy mechanisms to mitigate these risks, such as free allowances and Border Carbon Adjustments (BCAs), while highlighting the industry's strategic role in providing essential materials for low-carbon infrastructure. The brief argues that because the mining and metals sector is emissions-intensive and trade-exposed, policy design must account for specific commodity characteristics and long investment cycles to avoid jeopardizing economic viability and environmental integrity.

The document argues that GHG offsets are a critical component of effective climate policy, providing flexibility for regulated industrial emitters and expanding emission reductions to non-regulated sectors. Through a review of international and domestic systems and original CIMS modelling, the brief demonstrates that offsets can significantly lower the societal cost of carbon policies. It proposes two primary implementation paths: integrating offsets as a compliance mechanism within sector-by-sector regulations or establishing a separate, independent offset regime to cover sectors like agriculture and waste.

The document argues that integrating offsets into Canada's GHG regulations can significantly lower compliance costs for industrial emitters and expand emission reductions to difficult-to-regulate sectors like agriculture and forestry. It highlights that offsets are not exclusive to cap-and-trade systems but can complement performance standards, as seen in jurisdictions like Alberta and New South Wales. Modelling suggests that unlimited access to domestic offsets could reduce costs for industrial emitters by up to 40% and nearly double total emission reductions when expanding coverage. The brief proposes two implementation paths: allowing offsets for direct compliance within sector regulations or establishing a separate, independent carbon management fund.

The document presents a framework for a global energy assessment to support the Rio+20 Earth Summit, focusing on a 'triple global energy challenge': providing affordable energy for all, phasing out fossil fuels to stabilize the climate, and operating within Earth system boundaries. It proposes a 'new model' of development where all countries reach a GDP per capita equivalent to current middle-income levels by 2050, requiring a massive transition to renewable energy and efficiency. The authors recommend the adoption of strategic principles, including a transparent global investment fund for renewables in poor economies and the use of the planetary boundaries framework to manage environmental risks.

The research evaluates the transition from voluntary to mandatory emissions trading in Japan using the CASE-ASIA model. It compares two primary designs—one including the electricity sector in the ETS and one applying a CO2 tax to it—across various allocation modes including full auctioning, border adjustments (BA), and output-based allocation (OBA). The findings highlight a critical trade-off between electricity prices and industrial product prices, noting that border adjustments for exports are essential for Japan due to its high export volume of steel and cement. While OBA is most effective at limiting production decreases, the study concludes there is no single superior design, and policy choices will depend on government priorities regarding revenue and competitiveness.

The document argues that traditional separations between adaptation, mitigation, and development are insufficient. It proposes 'climate compatible development' as a framework to achieve 'triple win' outcomes: low emissions, high resilience, and sustained human development. It highlights a new development landscape where climate finance, shifting trade patterns, and technological innovation redefine economic growth, particularly for developing nations.

The paper examines how to equalise carbon costs between domestic and imported cement and clinker. It identifies two primary calculation requirements: the difference in carbon costs of production and the carbon intensity of imported products. The author evaluates three options for determining carbon intensity—plant-by-plant assessment, benchmarking, and default values—concluding that a system of stringent default factors with an option for plant-level evidence is the most practical compromise to balance accuracy with administrative feasibility.

The document investigates whether public finance-facilitating tools can act as a 'game-changer' for low-carbon investment in developing countries. It identifies that while these tools can address various risks and increase liquidity, they are not a substitute for ambitious climate policies and direct payment mechanisms. Key challenges include a lack of 'deal flow' in less advanced economies, the risk of crowding out private capital, and the inherent risk-aversion of public finance institutions that must maintain high credit ratings.

The document analyzes the cement industry's response to carbon pricing, highlighting that while short-term impacts involve limited cost pass-through to consumers, long-term risks include the relocation of production to non-constrained regions. It argues that border adjustment measures (BAM) are more effective than free allowances at preserving carbon price signals and deterring investment leakage, particularly given the capital-intensive nature of the industry and high regional variations in production costs.

The study uses the POLES model to assess how different levels of economic growth and convergence between developed and developing nations affect the energy mix and abatement costs required to reduce global CO2 emissions by 50% by 2050. It finds that low stabilisation is technically feasible and economically viable across all scenarios, with total abatement costs representing less than 2% of global GDP by 2050. However, the results highlight that high convergence increases the reliance on Carbon Capture and Storage (CCS) and places a higher absolute burden on developing countries, while developed nations continue to bear the majority of the costs.

The paper assesses how different carbon tax rates (10 and 100 yuan/tCO2) affect various Chinese industrial sectors. It finds that while a low carbon price is a safe starting point, a higher price of 100 yuan/tCO2 would significantly impact energy-intensive sectors like ferrous metals and electricity, potentially reducing GDP by 1.1% unless revenue is redistributed to stimulate consumption. The study highlights the electricity sector as the primary driver for CO2 emission reductions and suggests that targeted carbon pricing for energy-intensive sectors could be more efficient than a nationwide policy.

The analysis indicates that South Africa is vulnerable to border carbon adjustments (BCAs) from the US and EU, with potential annual charges of €380 million and US$210 million respectively. The non-ferrous metals and iron and steel sectors are the most exposed, facing ad valorem tax equivalents exceeding 10%. To mitigate these risks, the document suggests South Africa could pursue WTO redress or negotiate sectoral emissions reduction agreements to gain exemptions.

The document examines the risk of carbon leakage and the use of Border Carbon Adjustments (BCAs) to mitigate cost asymmetries created by carbon pricing. It specifically analyzes the exposure of Chinese exports to these measures, noting that the impact varies significantly based on the products included, the CO2 price applied, and the method used to assess CO2 content.

The report finds that the EU ETS is significantly oversupplied, with industrial sectors accumulating large surpluses of permits while the power sector faces a shortfall. This imbalance, exacerbated by the 2008 recession, threatens to weaken the Phase 3 cap by approximately 1.9Gt. The author highlights abuses in international offsetting, where surplus-holding installations use offsets for profit (arbitrage) or to subsidize foreign competitors. To rectify this, the report recommends a 1.7Gt set-aside of Phase 3 permits, a steeper annual cap reduction of 2.4% by 2016, and increased transparency in reporting installation ownership and waste gas transfers.

The document assesses how different BCA designs—specifically direct versus life-cycle emissions and varying carbon prices—would affect Chinese exports. It finds that while certain sectors like iron and steel are highly exposed, the overall economic impact on China's total exports would be limited, potentially reducing the incentive for exporters to lower emissions rather than divert trade.

The paper uses the CASE II model to analyze how different EU ETS allocation modes and emissions targets (-21% to -34%) affect carbon leakage and production in the cement, aluminium, steel, and electricity sectors. It finds that while output-based allocation (OBA) and border adjustments (BA) can mitigate leakage, they create different trade-offs regarding production levels and electricity prices. The author concludes that carbon leakage must be readdressed if the EU raises its ambition, as the impacts vary significantly by sector and allocation method.

The report estimates that the currently proposed EU ETS Phase III structure would raise between €150-190bn under a 20% emissions reduction target, increasing to €200-310bn if the target is raised to 30%. Germany is projected to receive the highest proportion of these revenues. The authors argue that these funds should be prioritised for climate-related expenditures, such as carbon capture and storage (CCS) demonstrations, low-carbon RD&D, and energy efficiency improvements for vulnerable groups. The report also explores an alternative scenario where the cement and steel sectors are fully auctioned with border levelling; this would increase revenues by €18-22bn from cement and €14-17bn from steel under a 20% target. While some suggest using these funds for national debt reduction, the authors warn that this could damage the legitimacy of the EU ETS, though they acknowledge it as a potential short-term transitional option for severely indebted Member States.

The document estimates that Phase III of the EU ETS will generate between €150-190bn in revenues across the EU by 2020, potentially rising to €200-310bn if a 30% reduction target is adopted. Germany is projected to receive the highest proportion of these revenues, while Italy, Poland, Spain, and the UK are each expected to accrue over €10bn from the power sector alone. The briefing also explores the financial impact of expanding auctioning to the cement and steel sectors and suggests strategic uses for these funds, including carbon capture and storage (CCS) demonstration, renewable energy RD&D, grid infrastructure, and international climate finance.

The report examines the role of public policy in catalyzing private investment for climate mitigation and adaptation, specifically in the energy, forestry, agriculture, transport, building, and waste sectors. It analyzes success stories from Brazil, China, and India, highlighting the effectiveness of targets, carbon pricing, and regulatory instruments. Additionally, it surveys 17 international public funding sources, including multilateral funds like the Climate Investment Funds and bilateral initiatives such as the Amazon Fund, detailing their governance, eligibility, and financial instruments.

The report evaluates the EU ETS, concluding that emissions trading is an effective tool for reducing CO2 emissions with modest macroeconomic impacts. It highlights the risks of free allowance allocation, such as windfall profits and reduced economic efficiency, and recommends a transition toward auctioning. The document also identifies that international competitiveness risks are concentrated in a few carbon-intensive sectors and suggests tailored solutions like benchmarked free allocation or multilateral border adjustments to prevent carbon leakage.
