R134a GWP: global warming potential (AR4, AR5, AR6)
R134a (HFC-134a) has a 100-year global warming potential (GWP) of 1,300 to 1,430 under AR4, 1,300 under AR5, 1,530 under AR6, and 1,470 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.
