N2O GWP: global warming potential (AR4, AR5, AR6)

N2O (R744a) has a 100-year global warming potential (GWP) of 265 to 298 under AR4, 265 under AR5, 273 under AR6, and 273 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.
