Under Section 611 of the Clean Air Act, manufacturers must label products containing or made with ozone-depleting substances (ODSODSA compound that contributes to stratospheric ozone depletion. ODS include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, 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. A detailed list (http://www.epa.gov/ozone/science/ods/index.html) of class I and class II substances with their ODPs, GWPs, and CAS numbers are available.). EPA regulations apply to both Class I ODS and Class II ODS (hydrochlorofluorocarbons). The labeling requirements for Class I ODS have been in effect since 1993; the requirements for Class II ODS came into effect on January 1, 2015.
