The CFC Problem

The accumulation of many critical scientific studies has built the consensus that the ozone layer must be protected from chlorofluorocarbons (CFCs) as they deplete the ozone layer, causing damage to both the environment and humans. By signing the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987, more than 70 countries agreed to phase out the use and production of CFCs. The number of counties that have since signed on to date exceeds 150. Under the terms of the 1992 Copenhagen Amendment, the latest CFC action agreement, the last day to legally manufacture CFCs in developed countries was December 31, 1995.
