• Usage:
• Fully halogenated chlorofluorocarbons (cfcs) such as dichlorofluoromethane were scheduled for production phase-out in 1987 by the montreal protocol. Although originally scheduled for 50% production phase-out by the year 2000 in developed countries, the worsening ozone depletion has forced acceleration of the cfc phase-out.
