The use of HCFCs is regulated under the Montreal Protocol, an international treaty aimed at phasing out substances that deplete the ozone layer. Amendments to the protocol have resulted in a structured phase-out schedule for HCFCs, with complete elimination targeted in most developed countries by 2020 and in developing countries by 2030. National regulations may also restrict the use, production, and import of HCFCs, encouraging the adoption of more environmentally friendly alternatives.
