Global warming potential values of hydrofluorocarbon refrigerants

Here are lists of HFCs and HFC blends, and their global warming potentials (GWP). For the purposes of the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 and the Ozone Protection and Synthetic Greenhouse Gas Management Regulations 1995, 100-year global warming potential is taken from the Intergovernmental Panel on Climate Change (IPCC) fourth assessment report, 2007 (AR4) – the same as used in the Montreal Protocol on Substances that Deplete the Ozone Layer.

Some refrigerants are not single chemicals but a mixture of two or more chemicals, called blends. HFC blends may contain only HFCs, or HFCs mixed with other chemicals. For example, R‑410A is made up of 50% R‑32 and 50% R‑125.
