This paper recommends a system of upstream taxes on fossil fuels, combined with refunds for downstream emissions capture, to reduce carbon and local pollution emissions. Motor fuel taxes should also account for congestion and other externalities associated with vehicle use, at least until...

This paper assesses the Brazilian economy's exposure to climate change focusing on two key areas: agriculture and hydropower. While climate vulnerabilities are significant and recent patterns of land-use further amplify climate change risk, Brazil's opportunities for green growth are vast. Given...

Large reductions in global emissions are needed for the world to be on track to meet global temperature goals. Asia-Pacific countries have a critical role in emissions reduction given their large and rising share in global emissions. This paper discusses the main opportunities and behavioral...

Internationally coordinated climate mitigation policies can effectively put the world on a path toward achieving the agreed Paris temperature goals. Such coordination could be initiated by large players, such as China, the US, India, the African Union, and the European Union. We find that the...

This paper provides a comprehensive global, regional, and country-level update of: (i) efficient fossil fuel prices to reflect supply and environmental costs; and (ii) subsidies implied by charging below efficient fuel prices. Globally, fossil fuel subsidies were $7 trillion in 2022 or 7.1...

To stabilize the climate, global greenhouse gas emissions must be cut by 25 to 50 percent by 2030 compared to 2019. Such an unprecedented rate of decarbonization necessitates climate mitigation policies across countries, notably carbon pricing, fossil fuel subsidy reform, renewable subsidies,...

This paper discusses potential elements of a comprehensive strategy for making headway on Türkiye's net zero emissions pedge for 2053. These elements include: (i) aligning 2030 emissions commitments with long term neutrality; (ii) implementing a carbon price rising to an ilustrative $75 per...

There is growing interest in international coordination over climate mitigation policy. Climate clubs or international carbon price floors could complement the Paris Agreement by helping to deliver the near-term cuts in global greenhouse gas emissions needed to contain global warming to 1.5 to...
