Montreal Protocol

Definition

The Montreal Protocol is an international treaty that was designed to phase out substances that deplete the ozone layer, particularly chlorofluorocarbons (CFCs) and other ozone-depleting chemicals. Adopted in 1987, this agreement represents a significant milestone in global environmental regulations, as it established a framework for countries to cooperate and take action towards protecting the ozone layer, which plays a crucial role in shielding the Earth from harmful ultraviolet radiation.
