Montreal Protocol
The Montreal Protocol on Substances That Deplete the Ozone Layer (usually called simply the Montreal Protocol) is the 1987 international treaty governing the use of chlorofluorocarbons (CFCs).[1] It was signed in January 1989 by most industrialized nations.
Montreal Protocol and its amendments control the phaseout of ozone-depleting substance (ODS) production and use. Under the protocol, several international organizations report on the science of ozone depletion, implement projects to help move away from ODS, and provide a forum for policy discussions. In addition, the Multilateral Fund provides resources to developing nations to promote the transition to "ozone-safe technologies".
The original document called for a 50-percent reduction in CFC use by 1992 relative to 1986 levels. The subsequent London Agreement called for a complete elimination of CFC use by 2000. The Copenhagen Agreement, which called for a complete phaseout by January 1, 1996, was implemented by the U.S. Environmental Protection Agency.
