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.

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. Calculated using the blend of gases taken from UNEP and applying GWPs from IPCC AR6. Blend: R-22/152a/124 (53.0/13.0/34.0). Source URL: https://ozone.unep.org/lists-substances-and-blends
