Fact Sheet: HCFCs

Partially halogenated chlorofluorocarbons (HCFCs) are used as refrigerants, propellants or solvents. HCFCs are manmade substances that are chemically stable, non-flammable, odourless and tasteless. They are hydrocarbons whose hydrogen atoms have been partially replaced with the halogens fluorine and chlorine. Compared to CFCs (e.g. R 12 ODP = 1), they are less stable and have both a lower ozone depletion potential (ODP = 0,02-0,06) and a lower direct global warming potential (GWP = 76-12,100). In Europe, HCFCs are not permissible as refrigerants in new plants.
