Fig. 2: Abatement potential of mass emissions and global warming potential (GWP) and ozone depleting potential (ODP)-weighted emissions of the two fluorocarbon categories, under scenario-based analysis.

a Annual GWP-weighted emissions of fluorocarbons in each geographic area under the business-as-usual (BAU, S1) scenario, from 1986 to 2060. b, c Cumulative GWP-weighted emission and mitigation via recovery and destruction actions by region and by sector, under the BAU scenario from 2022 to 2060. A5 parties include China and other A5, while non-A5 parties include Japan, North America (Canada and the USA only), European non-A5 and other non-A5 parties. End-use sectors include domestic refrigerator and freezer (DRF), room air conditioner (RAC), mobile air conditioner (MAC), industrial and commercial refrigeration (ICR), polyurethane rigid (PUR) foam, and extruded polystyrene (XPS) foam. d–f Mass emissions, ODP-weighted emissions and GWP-weighted emissions and their abatement potential of the two fluorocarbon categories under various scenarios from 1986 to 2060; 2021 served as the benchmark year. Under the BAU scenario, the global abatement practices between 2022 and 2060 will remain at the same level as that in 2021. Under Scenarios 2 (S2) and 3 (S3), Best Environmental Practices (BEPs) for emissions abatement will be partially applied in A5 parties between 2022 and 2060. S2 focuses on the end-of-life (EoL) stage, while S3 covers the use and EoL stages. Under Scenario 4 (S4), BEPs will be fully applied globally for use and EoL stages starting in 2023.
