The Montreal Protocol, an international treaty adopted in 1987, specifically addresses the production and consumption of artificial chemicals that deplete the ozone layer, primarily chlorofluorocarbons (CFCs). Its objective is to phase out these substances, thereby protecting the stratospheric ozone layer. The Bretton Woods Conference established the post-WWII international economic order, the Kyoto Protocol targeted greenhouse gas emissions, and the Nagoya Protocol deals with access to genetic resources and benefit-sharing.
