SAR refers to the IPCC Second Assessment Report (1995) used for reporting under the UNFCCC.

c The perturbation lifetime for methane is 12 years as in the TAR (see also Section 7.4). The GWP for methane includes indirect effects from enhancements of ozone and stratospheric water vapour (see Section 2.10.3.1).
