What date did the clean air act require CFC's to be phased out completely?

The Clean Air Act, specifically through the amendments made in 1990, mandated the complete phase-out of chlorofluorocarbons (CFCs) by January 1, 1996, for most uses, with some exceptions extending to 2000 for specific applications. This was part of a broader effort to protect the ozone layer and reduce environmental harm. The global commitment to phase out CFCs was also reinforced by the Montreal Protocol, signed in 1987.
