This paper calculates, for the top twenty emitting countries, how much pricing of carbon dioxide (CO2) emissions is in their own national interests due to domestic co-benefits(leaving aside the global climate benefits). On average, nationally efficient prices are substantial, $57.5 per ton of...

This paper assesses the rationale, design, and impacts of border carbon adjustments (BCAs). Large disparities in carbon pricing between countries raise concerns about competitiveness and emissions leakage. BCAs are potentially the most effective domestic instrument for addressing these...

Major carbon-pricing systems in Europe and North America involve multiple jurisdictions (countries or states). Individual jurisdictions often pursue additional initiatives—such as unilateral carbon price floors, legislation to phase out coal, aviation taxes or support programs for renewable...

The United States has pledged to become carbon neutral by 2050, meet sectoral objectives (e.g., for carbon free power, electric vehicles) and encourage greater mitigation among large emitting countries and of international transportation emissions. Fiscal policies at the national, sectoral, and...

Finland has pledged to cut net greenhouse gas emissions to zero by 2035 and has sectoral targets for deploying electric vehicles, phasing out coal generation, and oil-based space heating. Fiscal policies at the national and sectoral level could play a critical role in achieving these objectives....

To reach the global net-zero goal, the level of carbon emissions has to fall substantially at speed rarely seen in history, highlighting the need to identify structural breaks in carbon emission patterns and understand forces that could bring about such breaks. In this paper, we identify and...

The UK has pledged to cut greenhouse gases 57 percent below 1990 levels by 2030, to be emisisons neutral by 2050, and to phase out internal combustion engine vehicles by 2030. Much progress has been made, but fully achieving these ambitious objectives with the current policy framework will be...
