Emission factor summary

The Methane - fossil GWP value should be used for methane emissions from fossil fuel fugitive emission sources (e.g. oil & gas systems coal mining) and industrial processes where carbon in methane is of fossil origin (e.g. carbide production ethylene production). This GWP value includes the added radiative forcing effect from CO2 that is formed from the oxidation of methane which occurs at the end of a methane molecule’s atmospheric lifetime and then persists for the remainder of the 100-year time horizon.
