CFCs (chlorofluorocarbons) and HFCs (hydrochlorofluorocarbons) are often called freons. They contribute to depletion of the ozone layer. In the Montreol Protocol, the intention to stop all use of such substances has been internationally agreed. The Swedish Riksdag (parliament) has enacted a phase-out plan for CFCs and also for their substitutes, HCFCs.
CFC, HCFC and HFC turnover in Sweden

Total use of these substances has declined over the years and now seems to have stabilized somewhat below 1,000 tonnes. The CFC turnover has been reduced to less than 100 kg. Also, use of the substitution substances HCFCs has continued to go down. In Sweden about 2 tonnes of HCFCs were used during 2010. The even newer replacement chemicals HFCs now constitute almost all use of this kind of substances. They are used as refrigerants, for foaming of plastics, in fire extinguishers and as cleaning agents.
