Despite early skepticism, the risk of a thinning ozone layer was such that an international U.N. conference was convened in Vienna to address this problem. The participating countries and international bodies, including the United States, the European Union and other major producers and users of CFCs, afterward met in Montreal to negotiate an agreement setting out a specific program to reduce the production and use of CFCs.
