HCFCs (like CFCs) are found mainly in insulation materials, in various product areas.
In Sweden, HCFCs have been used in the manufacture of foam-blowing agents for insulation. Today, HCFCs may be used only as coolants in existing refrigeration, freezers and air-conditioning units. The Swedish Environmental Protection Agency has recommended that the Government should impose a complete ban on the use of HCFCs by 2010.
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.
HCFCs 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.
