The document outlines a proposed carbon tax for South Africa, starting at R120 per tCO2-eq in 2015 with annual increases of 10% through 2019. It argues that a carbon tax is more suitable than an emissions trading system (ETS) in the short term due to the oligopolistic nature of the domestic energy sector. The design includes a basic tax-free threshold of 60%, with additional allowances for trade-exposed and process-emission sectors, and the possibility of using carbon offsets to reduce tax liability. Economic modelling suggests the tax would have a largely neutral impact on GDP and employment if revenues are recycled effectively through tax shifting or government investment. The paper also details complementary flagship programmes in energy efficiency, renewable energy, and public transport to support a just transition.

The policy brief analyzes four regulatory scenarios for Canada's oil and gas sector, pairing emission-intensity improvements (20% to 40%) with price ceilings ($20 to $60). It argues that a 40% intensity standard with a two-tiered price ceiling ($30 and $60) provides an optimal balance by delivering 42 megatonnes of compliance in 2020 at an average cost of $28 per tonne. The author notes that while higher intensity targets increase costs, the average cost per barrel remains low (under $1), suggesting that such regulations would not significantly deter industry investment, as project hurdle rates already account for a $40 marginal cost.

The research uses a production function based on a sample of 40 hydroelectric plants to model the relationship between runoff and revenue in Costa Rica. Projections for 2100 under IPCC scenarios A2, A1B, and B1 indicate a significant reduction in hydropower production, estimated between 41% and 43%. These changes translate to aggregate revenue losses ranging from 41% in the sustainable B1 scenario to 49% in the A1B scenario. The study also explores technological adaptation, finding that doubling installed capacity would be required to achieve a revenue increase of 3% to 18% under these climate scenarios.

The report argues that EU biofuel policies, particularly those supporting conventional food-based biofuels, are not cost-effective and often fail to meet their stated public good objectives. It finds that significant public subsidies—estimated between EUR 5.5 and 6.9 billion in 2011—support an industry where benefits are increasingly captured by non-EU suppliers rather than EU farmers. The analysis highlights that conventional biofuels can lead to net increases in greenhouse gas emissions when indirect land use change (ILUC) is considered and contribute to higher global food prices. The report suggests that tightening vehicle emission standards to 95 gCO2/km by 2020 would be a significantly cheaper and more effective way to abate carbon emissions than subsidizing biofuels. It recommends phasing out support for food-based biofuels and implementing a 5 per cent cap on their contribution to renewable energy targets.

The document argues that Ontario should implement a unified carbon-pricing scheme, specifically a cap-and-trade system, to preempt federal sector-by-sector regulations and ensure cost-effective mitigation. Using economic modelling, the authors suggest that full compliance flexibility—including offsets and potential linking with the Western Climate Initiative (WCI)—could reduce compliance costs to below $15 per tonne by 2020. The brief cautions against overcompensating firms through free permit allocations, particularly in the electricity sector, to avoid windfall profits, and suggests a 25,000 tonne coverage threshold to align with California and Quebec systems.

The National Climate Change Action Plan 2013-2017 provides a strategic roadmap for Kenya to reduce its vulnerability to climate change while maintaining low greenhouse gas emissions. It identifies priority actions across sectors such as agriculture, energy, forestry, and transport, and proposes the establishment of a National Climate Change Council and a Kenya Climate Fund to coordinate governance and finance. The plan emphasizes a 'low carbon climate resilient development pathway' that aligns with Kenya Vision 2030, estimating total investment requirements at approximately KSh 1,085 billion (USD 12.76 billion) for the five-year period.

The document argues that rigid performance standards for Canada's oil and gas sector are likely to result in non-compliance and high costs due to the diverse abatement potentials across subsectors. By implementing flexibility mechanisms—such as in-sector credit trading and out-of-sector options like low-cost domestic reductions (LCDRs) and price ceilings—the government can achieve more stringent emissions intensity targets. Modelling suggests that while a 20% intensity improvement is achievable with in-sector flexibility, a 50% improvement requires flexibility beyond the sector to be feasible.

The document uses a global-to-local modelling approach to project land use changes in Vietnam up to 2030. It finds that economic growth and urbanisation will lead to a significant loss of paddy rice land and protected forests, while climate-induced flooding poses a severe threat to the Red River and Mekong River Deltas. The study highlights critical policy trade-offs between reducing greenhouse gas emissions through reforestation and maintaining national food security targets.

The research paper evaluates the economic and emissions impacts of increasing the EU's 2020 GHG reduction target to 30%. Using the E3MG model, it focuses on three energy-intensive sectors: iron and steel, aluminium, and cement. The findings indicate that while a 30% target significantly increases EU ETS allowance prices, there is no evidence of substantial carbon leakage through import substitution. Border adjustment measures partially protect EU output but have a negligible macroeconomic impact, as the affected sectors collectively account for less than 1% of EU GDP.

The paper evaluates the EU ETS allocation method—specifically the New Entrants Reserve (NER) and grandfathering—against output-based allocation (OBA), full auctioning, and border adjustments in the cement industry. It finds that while the EU ETS method effectively tackles carbon leakage, it creates economic distortions between new and existing plants, leading to lower overall welfare compared to border adjustments or OBA. The analysis suggests that the EU ETS method's primary advantage is its lower distributional impact on consumers and producers.

The paper examines the potential for an employment double dividend in Spain, where carbon taxes are used to fund reductions in labour taxes. It reviews previous CGE models and introduces a new model that accounts for Spain's significant informal labour market. The authors find that recycling carbon tax revenues into labour tax reductions can significantly decrease unemployment and increase overall welfare, especially when accounting for the reduction of local pollutants.

The brief uses the Canadian Integrated Modelling System (CIMS) to evaluate proposed regulations requiring new or modified coal plants to meet a performance standard of 375 g CO2e/kWh. The analysis projects that these regulations would reduce electricity sector emissions by 5 million tonnes (Mt) in 2020 and 20 Mt by 2030, with an average cost of $26 per tonne of GHG reduced. The findings indicate that coal generation would be primarily displaced by natural gas turbines, which are expected to account for 77-78% of the replacement, while carbon capture and storage (CCS) and renewables would play smaller roles.

The paper examines the 'double dividend' hypothesis in Spain, arguing that shifting the tax burden from labour to carbon can improve both environmental and economic outcomes. By incorporating the shadow economy into its model, the authors find that reducing labour taxes increases the demand for formal labour, encouraging workers to move from the informal sector to the formal economy. This transition increases official GDP and overall welfare. The study concludes that the potential welfare gains from such reforms are higher in countries with larger initial shadow economies and higher unemployment rates.

The document uses the POLES energy system model to assess how varying levels of economic growth and convergence between developed and developing nations affect the cost of climate stabilisation. It finds that limiting warming to 2°C is technically feasible and economically viable across all tested scenarios, with global abatement costs remaining below 2% of GDP by 2050. While modest growth makes stabilisation more likely, high convergence increases the absolute and relative economic burden on developing countries and increases reliance on future technologies like Carbon Capture and Storage (CCS).

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 report assesses the EU's Climate and Energy Package, concluding that the 20% emissions reduction target by 2020 is insufficient to reach the 2050 goal of 80% reduction without incurring extreme economic costs in later decades. It recommends increasing the 2020 target to 30%, establishing a stringent 2030 EU ETS cap of 45-50% reduction, and shifting energy efficiency focus toward absolute energy savings in buildings and transport. The authors argue that these measures would reduce oil and gas dependency, foster the Low Carbon and Environmental Goods and Services (LCEGS) market, and prevent high-carbon infrastructure lock-in.

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 argues that the EU's current Climate and Energy Package is insufficient to reach its 2050 goal of 80-95% emissions reduction at a reasonable cost. It suggests that moving to a 30% reduction target by 2020, combined with proactive investment policies in the building and transport sectors and a more predictable carbon price signal via the ETS, would reduce long-term costs and prevent the EU from losing market share in low-carbon technologies to competitors like China and South Korea.

The paper argues that African development should be central to G20 objectives to enhance the forum's legitimacy and global economic rebalancing. It identifies key growth pillars for Africa—including infrastructure, private investment, human resource development, and trade—and suggests that the G20 can add value by focusing on 'beyond aid' issues. The authors recommend that the G20 establish permanent seats for Africa, create a high-level panel on sustainable infrastructure, and promote knowledge exchange platforms to share successful policy tools from emerging market economies. Case studies on South African outward FDI and Special Economic Zones (SEZs) illustrate potential pathways for diversifying investment and industrialization.
