Ozone Depletion International Agreements

The Montreal Protocol (1987) is the international treaty specifically designed to control and phase out ozone-depleting substances such as chlorofluorocarbons (CFCs) and halons. It is considered one of the most successful environmental treaties globally. The Bretton Woods Conference (1944) established the International Monetary Fund and World Bank but was not about environmental issues. The Kyoto Protocol (1997) addresses climate change and greenhouse gas emissions, not ozone depletion. The Nagoya Protocol (2014) deals with access to genetic resources and benefit sharing from biodiversity, not ozone depletion. Therefore, the Montreal Protocol is the correct answer. > Montreal Protocol = Ozone layer protection. CFCs/Halons phase-out. 1987 treaty. Answer: b.
