What are chlorofluorocarbons (CFCs)? Chlorofluorocarbons (CFCs) are a group of manufactured chemical compounds that contain chlorine, fluorine, and carbon. This group includes CFC-11, CFC-12, CFC-113, CFC-114, CFC-115, and many forms of Freon. They are colorless, odorless, nontoxic, nonflammable, and stable when emitted. When they are emitted and reach the stratosphere, they break apart and release chlorine atoms, which destroy the earthâs ozone layer. CFCs can last for more than 100 years in the stratosphere. Because they destroy the ozone layer, CFCs have been banned from production in the United States since December 31, 1995.
