[56] and in the same year the UNEP published new voluntary guidelines, [57] however many countries have not yet ratified the Kigali Amendment. From early 2020 HFCs (including R-404A, R-134a, and R-410A) are being superseded: Residential air-conditioning systems and heat pumps are increasingly using R-32. This still has a GWP of more than 600.
It is an isomer of the more-used 1,1,1,2-tetrafluoroethane (R-134a). It is used as a foam expansion agent and heat transfer fluid. [3] References
