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 is the latest installment of the U.S. Environmental Protection Agency’s (EPA’s) non-carbon dioxide (non-CO₂) greenhouse gas (GHG) assessments and combines two long-running EPA report series: Non-CO₂ Greenhouse Gases: International Emissions and Projections and Global Mitigation of Non-CO₂ Greenhouse Gases.

The full methodology used to develop the emission projections and mitigation estimates is documented in the peer-reviewed EPA report Global Non-CO₂ Greenhouse Gas Emissions Projections & Marginal Abatement Cost Analysis: Methodology Documentation.

The accompanying data sets to this report are also available through the Non-CO₂ Greenhouse Gas Data Tool. This is a data exploration tool for querying and visualizing the non-CO₂ GHG projections and mitigation assessments compiled in the report.
