Global Non-CO2 Greenhouse Gas Emission Projections & Mitigation: 2015-2050
Between 1990 and 2015, global non-CO2 emission levels rose by about 29%. Between 2015 and 2030, global non-CO2 emissions are estimated to continue to increase by approximately 17% under a business-as-usual scenario.
In 2030, the total global non-CO2 GHG mitigation potential is estimated to be approximately 3,807 MtCO2e, or 27% of non-CO2 GHG emissions in that year.
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.
