1987 Montreal Protocol The 1987 Montreal Protocol was an international treaty negotiated in Montreal to phase out substances that deplete the ozone layer. Negotiations involved representatives from the United Nations Environment Programme, the World Meteorological Organization, the United Nations General Assembly, and member states such as the United States, Soviet Union, United Kingdom, Canada, and Australia. Scientific assessments by teams connected to the World Health Organization, the Intergovernmental Panel on Climate Change, and laboratories affiliated with the National Aeronautics and Space Administration informed the agreement.
Negotiations followed discoveries by scientists including teams at the British Antarctic Survey, the University of Cambridge, and the National Oceanic and Atmospheric Administration that linked declines in stratospheric ozone to emissions of chlorofluorocarbons from industries represented by associations such as the Chemical Manufacturers Association and corporations like DuPont, Rohm and Haas, and 3M. Diplomatic talks occurred within frameworks involving the Vienna Convention for the Protection of the Ozone Layer, the United Nations Environment Programme, and delegations from countries such as India, China, Brazil, South Africa, and Japan. Scientific input from the Nobel Prize-associated climate community, and analyses referencing findings from the Antarctic Treaty System and research stations like Halley Research Station shaped negotiation positions.
The treaty established legally binding controls on production and consumption of ozone-depleting substances, listing groups like chlorofluorocarbons, halons, and methyl bromide used by sectors including refrigeration firms represented by Carrier Global Corporation, aerospace contractors such as Boeing, and agricultural exporters like Cargill. It set schedules for developed parties including members of the Organisation for Economic Co-operation and Development and for developing parties including members of the G77 and China. The protocol created mechanisms parallel to instruments like the Kyoto Protocol and the Paris Agreement for adjustments to control lists and for addressing substitutes promoted by companies such as Honeywell and Arkema.
Ratification campaigns engaged national legislatures such as the United States Senate, the Parliament of the United Kingdom, the Knesset, and the Parliament of Canada, and regulatory agencies including the Environmental Protection Agency and the European Commission. The treaty entered into force after instruments of ratification were deposited by states like France, Germany, Italy, and Spain, meeting thresholds similar to those in agreements such as the Montreal Accords and the Convention on International Trade in Endangered Species of Wild Fauna and Flora. The process involved diplomatic coordination with multilateral lenders such as the World Bank to support compliance.
Implementation relied on national implementing authorities comparable to the United Nations Environment Programme structures and multilateral fund administration reminiscent of the Global Environment Facility. Compliance used reporting schedules, production control licensing systems, and verification protocols involving agencies like the International Civil Aviation Organization and scientific monitoring by the European Space Agency and the National Aeronautics and Space Administration. Non-compliance procedures invoked consultations with bodies modeled after panels in the World Trade Organization and dispute-resolution practices seen in the International Court of Justice.
Scientific assessments by panels akin to the Intergovernmental Panel on Climate Change and observational programs run by the National Oceanic and Atmospheric Administration and the European Centre for Medium-Range Weather Forecasts documented reductions in atmospheric concentrations of key compounds monitored by networks like the Global Atmosphere Watch. Recovery of ozone over regions monitored by stations such as Davis Station and satellites operated by agencies like the European Space Agency was linked to declines in UV-B fluxes relevant to public health institutions including the World Health Organization. Studies published in journals bridging research communities including contributors from the Scripps Institution of Oceanography, MIT, and Harvard University evaluated interactions with climate forcing described by researchers associated with the Princeton Plasma Physics Laboratory.
The protocol was adjusted and amended through meetings of parties similar to the procedure in the Convention on Biological Diversity, resulting in subsequent decisions adding substances and accelerating phase-out timetables. Major adjustments involved agreements on methyl bromide and hydrofluorocarbons influenced by proposals from negotiating blocs including the European Union, the Africa Group, and the Umbrella Group. Amendments were negotiated at conferences akin to sessions of the Conference of the Parties and implemented with support from funds modeled on the Multilateral Fund.
Industries such as manufacturers of refrigeration equipment represented by Carrier Global Corporation and chemical producers like DuPont, Honeywell, and BASF invested in alternatives including hydrochlorofluorocarbons and hydrofluorocarbons, while later market shifts favored low-global-warming options promoted by firms such as Johnson Controls and Whirlpool. Financial assistance initiatives involved institutions like the World Bank and investment policies influenced by groups such as the Organisation for Economic Co-operation and Development. Trade impacts engaged exporters from China, Mexico, and Germany and were mediated through standards bodies comparable to the International Organization for Standardization.
The treaty is cited alongside landmark instruments such as the United Nations Framework Convention on Climate Change, the Kyoto Protocol, and the Paris Agreement as a model for multilateral environmental governance. Its multistakeholder approach informed negotiations in arenas including the World Trade Organization and the G20, and its success is referenced in analyses by institutions such as the World Bank and the United Nations Development Programme. The protocol’s frameworks for science-policy interaction influenced later initiatives by entities including the Intergovernmental Panel on Climate Change and the United Nations Environment Programme.
