Fig. 1: The total radiative forcing and EECl from HCFCs.
From: A decrease in radiative forcing and equivalent effective chlorine from hydrochlorofluorocarbons
a, The total direct global radiative forcing from HCFCs until 2023 and the projected radiative forcing until 2100. b, The EECl from HCFCs until 2023 and the projected EECl until 2100. The projection is for HCFC-22, HCFC-141b and HCFC-142b only (Methods), which are shown to the right of the white dotted line. The category ‘other HCFCs’ contains HCFC-124, HCFC-132b, HCFC-31 and HCFC-133a. We assume all other HCFCs have a negligible contribution to radiative forcing and EECl. Thin black lines indicate the return to 1980 levels.
