    Chlorofluorocarbons, also known as CFC's, were slowly “phased out” since the 1987 Montreal Protocol. Included in the Montreal Protocol were the clauses:

    from 1996 its calculated level of consumption and production of the controlled substances in Group I of Annex A does not exceed zero.”

    Thus you can determine that the ban on CFC’s in the United States and many of the other nations was officially 1996.
