CFCs will not be manufactured after December 31st 1995. This schedule has been set at both the national and the international level. The Montreal Protocol is the international treaty that protects the ozone layer. It was first signed in Montreal in 1987. The last significant changes to the Protocol were made when the countries met in Copenhagen in November 1992. And at that meeting the most important action taken was the acceleration of the production phaseout schedule for ozone depleting compounds. For CFCs, production halted at the end of 1995. And for HCFCs, which are much less destructive to the ozone layer than CFCs are, the phaseout schedule will start in the year 2003 and then will gradually lead to a total phaseout in the year 2030.
