The Methane - non fossil GWP should be used for combustion emissions and biogenic methane emissions. It does not include the oxidation to CO2 effect as the carbon at issue is either deemed not to be a net addition to the carbon cycle (i.e. of biogenic origin) or already accounted for in CO2 emissions from the same source. Retrieved from the EPA's GHG Emission Factors Hub (xlsx).
