Global and European HFC reported emissions compared to emissions derived from atmospheric monitoring

The Scientific Assessment 2022 Report (SAP2022, available here) provides revised forecasts for HFC emissions and compares reported global and regional emissions to these estimated from atmospheric monitoring. Projected emissions of HFCs based on current trends in consumption and emissions, national policies in several countries, and the Kigali Amendment, are lower than those projected in the 2018 Assessment. The new scenario also assumes that all countries adhere to the provisions of the Kigali Amendment. Compared to that scenario, the 2020–2050 cumulative emissions are reduced by 14–18 Pg CO2-eq [14,000 to 18,000 million tonnes CO2-eq] and the 2050 radiative forcing is reduced by 0.03 W m–2.
