The Vienna Convention and the Montreal Protocol have each been ratified by 196 nations and the European Union[12], making them the first universally ratified treaties in the history of the United Nations. [13] Because of its widespread adoption and implementation, the Montreal Protocol has been hailed as an example of exceptional international cooperation, with Kofi Annan calling it „perhaps the most successful international agreement to date.“ [14] [15] So what`s the matter? Well, it turns out that there is a whole difference between Montreal and Paris. Given all these factors and more, the Montreal Protocol is considered one of the most successful environmental agreements of all time. What the Parties to the Protocol have accomplished since 1987 is unprecedented and continues to be an inspiring example of what international cooperation can accomplish at its best. The Montreal Protocol is the international agreement that protects the Earth`s ozone layer through the global phase-out of ozone-depleting substances (SACO). All UN member countries have signed the Montreal Protocol and have all committed to phasing out sacolite substances used in refrigeration and air conditioning, foam blowing, aerosols, solvents and other applications. The Montreal Protocol on Substances that Deplete the Ozone Layer is a global agreement to protect the Earth`s ozone layer through the progressive depletion of chemicals that lead to depletion. This phase-out plan covers both the production and consumption of ozone-depleting substances. This historic agreement was signed in 1987 and entered into force in 1989. The means by which this agreement will be implemented in Canada are the Federal Substances that Deplete the Ozone and Alternatives to Halocarbons Act (ODSHAR), which was enacted under the Canadian Environmental Protection Act (CEPA). In April 2018, amendments to these regulations came into force, adding controls for HFCs in accordance with Canada`s obligations under the Kigali Addendum. The Montreal Protocol, concluded in 1987, is a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (SACO).

The Montreal Protocol had proved innovative and fruitful and was the first treaty to be universally ratified by all countries of the world. By leveraging this global participation, the Montreal Protocol has stimulated global investment in alternative technologies, many of which have been developed by United States companies, and has put the ozone layer, which was at risk, on the road to repair. „The [Montreal Protocol] benefited from a targeted sectoral agreement – the world of fluorinated gases,“ Zaelke said in an email. .
