Explanation
The Montreal Protocol, adopted in 1987, is the international treaty under which nations agreed to phase out the production and consumption of ozone-depleting substances such as CFCs and HCFCs. It is not a wage law, a compressor efficiency standard, or a metal recycling pledge. U.S. obligations under this treaty are carried out through the Clean Air Act.
