What was the primary focus of the Montreal Protocol?

The Montreal Protocol primarily focused on cutting back and eventually eliminating the use of chlorofluorocarbons (CFCs), along with other ozone-depleting substances. The protocol was signed in 1987 as a global agreement aimed at protecting the ozone layer by phasing out the production and consumption of substances that significantly harm it. CFCs were widely used in refrigeration, air conditioning, and aerosol propellants, and their release into the atmosphere was a major contributor to ozone layer depletion.

The Montreal Protocol is particularly notable for its strong international cooperation. It has been successful in reducing the atmospheric concentrations of CFCs and has significantly contributed to the recovery of the ozone layer. The treaty has undergone several amendments and adjustments to include additional harmful substances and to strengthen commitments from participating countries.

By focusing specifically on CFCs and other ozone-depleting chemicals, the protocol addressed a pressing environmental concern with a clear and direct approach, establishing a comprehensive framework for the reduction of these harmful substances globally.
