The Stockholm Environment Institute (SEI) used the Water Evaluation and Planning (WEAP) system and the Open Source Energy Modeling System (OSeMOSYS) to model climate change impacts on seven strategic river basins in Sub-Saharan Africa. The analysis found that all basins face significant economic risks, with the Niger River potentially facing costs up to $200 billion and the Zambezi River showing the highest uncertainty with impacts between $50 billion and $125 billion. To mitigate these risks, SEI recommends that policy-makers integrate climate change expertise into infrastructure planning through technical guidelines, open-data repositories, and professional training programs.

The research uses multiregional input-output tables and Computable General Equilibrium models to analyze how environmental change and extreme events impact supply chains and economic activities in delta regions. The analysis indicates that climate change could lead to a significant reduction in GDP per capita, specifically between 9% and 19.5% in the studied deltas, primarily through negative effects on fisheries, agriculture, and infrastructure.

The policy brief examines the interaction between the European Union's coal phase-out and the EU Emissions Trading System (EU ETS). It warns that closing coal plants without adjusting the ETS could create a 'coal bubble' of up to 6.18 billion excess permits by 2040, depressing carbon prices and undermining climate incentives. While the EU ETS supports the transition by making coal less profitable, the author argues it cannot deliver a full phase-out alone. The document recommends increasing the Market Stability Reserve (MSR) intake rate to 36% from 2024, increasing the Linear Reduction Factor to 4.2%, and allowing the cancellation of allowances for any closed ETS installation to maintain market effectiveness.

The document assesses the multifaceted threats climate change poses to global food security, highlighting that while some high-latitude regions may see productivity gains, the global South—especially sub-Saharan Africa—faces severe risks of yield losses and increased hunger. It argues for a systemic approach to adaptation, moving beyond autonomous adjustments to planned strategies. Key priorities include increasing public investment in agricultural research, adopting Climate-Smart Agriculture (CSA), expanding irrigation, and improving the resilience of food value chains. The authors emphasize that adaptation must be balanced with greenhouse gas mitigation and social equity, particularly regarding gender and youth in agriculture.

The document finds that Brazil can significantly increase agricultural output without deforestation by eliminating inefficiencies, though this requires substantial increases in operational costs and farm equipment investment.

The report finds that Brazil can significantly increase agricultural and livestock production without further deforestation by eliminating productivity inefficiencies. Achieving these gains would require substantial increases in operational costs and capital investment in equipment. The analysis suggests that converting low-productivity pasture to high-productivity cropland could further boost agricultural output by 26 percentage points.

The research finds a positive correlation between energy and resource misallocation in Brazilian industry, suggesting that improving the allocation of resources to the most productive firms would simultaneously increase aggregate productivity and energy efficiency. Using data from 2007 to 2015, the authors demonstrate that resource misallocation increased over this period, acting as the primary barrier to productivity growth. While the potential aggregate output gains from fully equalizing revenue productivity are substantial, ranging from 77.9% to 96.2%, the analysis reveals that capital distortions are significantly more impactful than electricity distortions in generating these losses. The study concludes that broad industrial policies targeting these binding distortions are more effective for improving aggregate energy efficiency than firm-level initiatives.

The report finds that the 45Q tax credit could lead to the annual capture and storage of approximately 49 million metric tonnes of CO2 by 2030 in the U.S. power sector, primarily through retrofits on coal and natural gas combined cycle (NGCC) plants. This deployment is found to be complementary to renewable energy growth and could meet two-thirds of the 2030 U.S. power sector goal set by the International Energy Agency (IEA) to limit global temperature rise to 2 degrees Celsius. The analysis emphasizes that the economics of the 45Q credit make enhanced oil recovery (EOR) more favorable than saline storage, necessitating rapid infrastructure development to realize the credit's full potential.

The report advocates for a shift in the role of hydropower within global energy grids, moving away from high-impact dams toward a mix of wind, solar, storage, and low-impact hydropower. It demonstrates through modeling in Chile and Uganda that protecting free-flowing rivers and national parks has minimal impact on system costs. The document highlights the Mekong River basin as a critical area where strategic planning could prevent the loss of migratory fish biomass and delta sediment. It concludes that achieving this vision requires system-scale planning, regulatory reform, and redirected financial flows from multilateral development banks and institutional investors.

The document outlines the technical framework for the 'Soot to Solar' analysis, utilizing the Regional Energy Deployment System (ReEDS) and HOMER Pro models to evaluate energy scenarios in Illinois. It specifies cost and performance assumptions for various generation technologies, calculates the social cost of carbon and health benefits of emission reductions, and assesses the feasibility of replacing natural gas peaker plants with storage and solar. Additionally, it includes land availability assessments for former coal sites and a public health impact analysis conducted with the Clean Air Task Force.

The document predicts that freezing federal fuel economy standards at 2020 levels would cost the U.S. economy $450 billion through 2050 and increase transportation sector greenhouse gas emissions by 11% by 2035. It notes that these costs and emissions increases would be lower if California retains its authority to set more stringent standards. The analysis indicates that while initial costs of manufacturing might decrease, these are outweighed by rising fuel expenses, with the primary beneficiaries being oil companies.

The 2018 Green Economy Barometer for Mongolia highlights a significant gap between the country's international commitments and domestic implementation. While Mongolia has adopted the Green Development Policy and the Sustainable Development Vision 2030, it ranked 79th out of 80 countries in the 2016 Global Green Economy Index. The report identifies severe environmental challenges, including air pollution in Ulaanbaatar, desertification affecting 77.8% of the territory, and water scarcity. Economically, the report argues that investing 4% of GDP annually into green development could reduce poverty to 10% and unemployment by 2% by 2030. Current green employment accounts for 9.9% of total jobs. Financial needs for energy efficiency, renewables, and pollution control are estimated at over 11 billion USD, though green financing remains limited.

The paper analyzes the supply curve of CERs from CDM projects, finding a significant volume of units available below €1 per unit, many of which do not require CER revenues to continue abatement. It concludes that without eligibility restrictions, CORSIA's demand for offsets up to 2035 would likely fail to raise CER prices or increase overall greenhouse gas abatement.

The analysis finds that the Pan-Canadian Framework (PCF), if fully implemented, will leave a 2030 emissions gap of 161 million metric tons (MMT), which is 3.7 times larger than the 44 MMT shortfall predicted by the Canadian government. While an 'Extended' scenario—strengthening PCF policies through 2050—comes closer to the 2030 target, it still falls short of Canada's mid-century goal to reduce emissions by 80-90 percent below 2005 levels. The report highlights that the carbon tax and methane capture are the most effective PCF policies for 2030, and that both the PCF and PCF Extended scenarios would result in significant annual economic savings and thousands of lives saved by 2050 due to reduced particulate matter emissions.

The paper introduces a demand-led post-Keynesian model to analyze the macroeconomic effects of transitioning to a low-carbon economy. It specifically explores a "downshifting" scenario where households voluntarily reduce their labor supply, comparing this to scenarios where consumption is reduced without labor withdrawal.

The document argues that restricting California's oil production can significantly lower global CO2 emissions because a portion of the avoided production is not replaced by other sources. It estimates that for every barrel of oil left in the ground in California, global consumption would drop by 0.2 to 0.6 barrels, leading to a reduction of 80 to 240 kg of CO2 per barrel. The brief identifies several policy options, including ceasing new well permits, implementing emissions performance standards, and targeting production in pollution-vulnerable areas. It notes that such measures are cost-competitive with other California climate strategies and could address 'carbon leakage' by complementing demand-side policies. Additionally, the report highlights that many of California's most productive oil fields are more GHG-intensive than global averages and are located in disadvantaged communities, making production limits a matter of environmental justice.

The study evaluates the impact of financing renewable energy through electricity surcharges versus alternative tax sources in Spain. Using a combined computable general equilibrium (CGE) and microsimulation (MS) model, the authors find that electricity surcharges are regressive, disproportionately affecting low-income households and vulnerable groups such as retirees. While exemptions for producers protect industrial competitiveness, they exacerbate the burden on households. Conversely, financing through lump-sum transfers or value-added taxes (VAT) is found to be more effective in reducing regressive effects and safeguarding welfare for low-income groups without significantly harming overall economic output.

The Union of Concerned Scientists argues that New Mexico should strengthen its renewable portfolio standard (RPS) to 80 percent by 2040 to ensure a cost-effective transition from coal to clean energy. Modeling shows that renewables are the most economically favorable choice, offering significant capital investment, job growth, and public health benefits without substantially increasing consumer electricity costs. The report warns against utility plans to overinvest in natural gas, which could lead to stranded assets and higher climate risks.

The document outlines the technical framework for analyzing New Mexico's energy transition, comparing a 'business-as-usual' baseline against a strengthened renewable portfolio standard (RPS). It specifies the cost, performance, and retirement assumptions for various power generation technologies and the economic parameters used to estimate job creation and local revenue from wind, solar, and transmission projects.

The report argues that reintegrating livestock into diversified cropping systems can improve farmer profits and reduce environmental degradation. Using economic and environmental modeling, it demonstrates that transitioning from corn-soy monocultures to perennial pastures and complex rotations can sequester soil carbon, reduce synthetic fertilizer and fuel use, and lower water footprints. However, the author notes that these systems typically produce less beef per acre, suggesting that the greatest benefits occur when improved management is paired with a reduction in overall beef consumption. The report concludes with policy recommendations for the USDA and Congress to incentivize regenerative practices through conservation programs, crop insurance reform, and increased agroecological research.
