"Halogenated Fluorocarbons, HFCs, and PFCs. Halogenated fluorocarbons are human-made compounds that include: chlorofluorocarbons

(CFCs), halons, methyl chloroform, carbon tetrachloride, methyl bromide, and hydrochlorofluorocarbons (HCFCs). These compounds not only

enhance the greenhouse effect, but also contribute to stratospheric ozone depletion. Under the Montreal Protocol and the Copenhagen Amendments,

which controls the production and consumption of these chemicals, the U.S. phased out the production and use of all halons by January 1, 1994 and

phased out CFCs, HCFCs, and other ozone-depleting substances (ODSs) by January 1, 1996. Perfluorinated carbons (PFCs) and hydrofluorocarbons

(HFCs), a family of CFC and HCFC replacements not covered under the Montreal Protocol, are also powerful greenhouse gases."
