The Montreal Protocol on Substances that Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances, most notably chlorofluorocarbons (CFCs).
Ratified in 1987, the Montreal Protocol is considered one of the most successful international environmental agreements. Its implementation has led to a significant reduction in the emission of ODS and the slow recovery of the ozone layer.
Sustainable development is a broader concept. Carbon trading and the goal of restricting global temperature increase below 2 °C are associated with efforts to combat climate change, primarily through the Kyoto Protocol and the Paris Agreement, respectively, not the Montreal Protocol.
