The EPA report provides historical and projected emissions data for 195 countries, along with technical and economic mitigation estimates for non-COâ‚‚ greenhouse gases (GHGs). The analysis helps assess national contributions to GHG emissions, historical progress in reductions, and mitigation opportunities. Updated projections indicate that overall non-COâ‚‚ GHG emissions by 2050 remain consistent with the 2019 report, though the industrial processes sector's share has increased, while emissions from the waste sector have declined. By 2030, CHâ‚„ emissions represent the greatest low or no-cost mitigation opportunities, including 55% of natural gas and oil systems and 65% of coal mines. Additionally, croplands and landfills account for over 68% of low or no-cost mitigation potential. By 2050, refrigeration and air conditioning will become the largest source of no-cost emission reductions. The total mitigation potential is estimated at 27% in 2030 and 33% in 2050, while no-cost mitigation options have decreased from 7% to 5% in 2030. The report’s data annex and online tool offer detailed projections and mitigation data for policy and research applications.
