Montreal Protocol

Definition

The Montreal Protocol is an international treaty established in 1987 to phase out the production and consumption of substances that deplete the ozone layer. This landmark agreement represents a significant global effort to reduce air pollution caused by chlorofluorocarbons (CFCs) and other ozone-depleting chemicals, ultimately protecting both human health and the environment.
