Previously HFC-1234ze(Z). Has an GWP value of less than 1. 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 Conversion Factors 2026: flat file published by the UK Government at the source URL.

Global Warming Potential (GWP) of a greenhouse gas not covered by the Kyoto Protocol and therefore reported under GHG Protocol outside of the scopes of an inventory. This should be used to report leakage from air-conditioning refrigeration units or other release to the atmosphere.
