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.

Global Warming Potential (GWP) of a greenhouse gas covered by the Kyoto Protocol and included within scope of an inventory prepared under GHG Protocol. This should be used to report leakage from air-conditioning refrigeration units or other release to the atmosphere. Retrieved from the CSV file "Koudemiddelen NL" from CO2 Emissiefactoren 2025.02 providing a standard list of CO2 emission factors.

Global Warming Potential (GWP) of a greenhouse gas covered by the Kyoto Protocol and included within scope of an inventory prepared under GHG Protocol. This should be used to report leakage from air-conditioning refrigeration units or other release to the atmosphere. Retrieved from Table 11, published by Cornerstone as the continuation of the U.S. EPA's GHG Emission Factors Hub.
