Global Non-CO2 Greenhouse Gas Emission Projections & Mitigation Potential: 2015-2050

The EPA technical report Global Non-CO₂ Greenhouse Gas Emission Projections & Mitigation Potential: 2015-2050 provides a consistent and comprehensive set of historical and projected estimates of emissions and technical and economic mitigation estimates of non-CO₂ GHGs form anthropogenic sources for 195 countries. The analysis provides information that can be used to understand national contributions of GHG emissions, historical progress on reductions, and mitigation opportunities. 

This report combines two long-running EPA report series: Non-CO₂ Greenhouse Gases: International Emissions and Projections and Global Mitigation of Non-CO₂ Greenhouse Gases.

The report data annex includes all emission projections and mitigation data tables.
