Ozone-Depleting Substance (ODS) is a compound that contributes to [[stratospheric]] ozone depletion.

ODS include [[CFC]]s, [[HCFC]]s, [[halons]], [[methyl bromide]], [[carbon tetrachloride]], and [[methyl chloroform]]. ODS are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere. When they break down, they release chlorine or bromine atoms, which then deplete ozone.

The [[EPA]] provides a list of [http://www.epa.gov/ozone/ods.html class I] and [http://www.epa.gov/ozone/ods2.html class II] substances with their [[ODP]]s, [[GWP]]s, and [[CAS]] numbers.

+ODSs include [[chlorofluorocarbon]]s (CFCs), [[hydrochlorofluorocarbon]]s (HCFCs), [[halons]], [[methyl bromide]], [[carbon tetrachloride]], and [[methyl chloroform]]. ODSs are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere. When they break down, they release [[chlorine]] or [[bromine]] radicals, which then catalyze the breakdown of [[ozone]] into [[oxygen]].
