R32 GWP: global warming potential (AR4, AR5, AR6)
R32 (HFC-32) has a 100-year global warming potential (GWP) of 675 to 677 under AR4, 677 under AR5, 771 under AR6, and 749 under WMO 2022.
A GWP is counted in kilograms of CO₂ equivalent (kg CO₂e) per kilogram of gas released.
GWP by IPCC report and horizon
One row per figure. When publishers print different figures under one report, each figure gets its own row.
