CFC ReplacementsThe success of ozone protection has been possible because science and industry have been able to develop and commercialize alternatives to ozone-depleting chemicals.
Worldwide production of CFCs, HCFCs, and HFCs are shown below:
Hydrochlorofluorcarbons have shorter lifetimes and lower ozone depleting potential than CFCs and these are short term replacements. Data on some hydrochlorofluorocarbons:
Long term, the CFCs should be replaced by HFCs. These contain no chlorine or bromine and their ozone depleting potential is zero. They do increase the global warming potential, however.
