Chlorofluorocarbons (CFCs), CFCS
Chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFCs) are found mainly in insulation materials, in various product areas. Certain CFCs used for industrial purposes are known by the trade name ‘Freon’.
CFCs have long been used as a refrigerant, in cooling and heat pumps, and in air-conditioning units, but like HCFCs they attracted attention when the phase-out of substances that deplete the ozone layer began in the 1980s.
Today, emissions take place mainly in the form of leaching from goods and products in which these ozone-depleting substances are used as coolants or in insulation materials.
CFCs contribute to the thinning of the ozone layer, and their use has therefore been restricted by international agreements and other means; see the Montreal Protocol. CFCs are banned in Sweden.
