“The [Montreal protocol] has benefited from the fact that it is a targeted sectoral agreement – the Fluorngas universe,” Zaelke said in an email. “This has allowed scientists, technologists and policy makers to learn faster, develop technology faster, and attract scientists, businesses and policy makers to gain confidence to do more and more.” It culminated in 1987 with the Montreal Protocol of the United States, a pioneering agreement on the prohibition of CFCs and other ozone-depleting substances. The agreement set a binding timetable for the gradual reduction of the main ozone-depleting substances and provided funds to developing countries to help them get out of these substances. In the meantime, the companies that produced these chemicals also arrived on board. The Montreal Protocol, which was finalized in 1987, is a comprehensive agreement to protect the stratospheric ozone layer by gradually reducing the production and consumption of ozone-depleting substances (SDGs). The Montreal Protocol has proven to be innovative and successful and is the first treaty to be universally ratified by all countries of the world. With this global participation, the Montreal Protocol stimulated global investments in alternative technologies, many of which were developed by U.S. companies, and put the ozone layer at risk on a repair path. Damage to the planet`s protective ozone layer has raised unprecedented concerns and action around the world.
Since the 1987 international agreement on the phasing out of ozone-depleting substances, 197 countries have ratified the Montreal Protocol. In January 2012, South Sudan ratified the Montreal Protocol, making it the first international environmental treaty to be fully ratified – a truly remarkable effort that reflects the overall acceptance and success of the agreement. The Montreal Protocol on Ozone Depleting Substances is a 1987 international agreement. It was designed to stop the production and importation of ozone-depleting substances and reduce their concentration in the atmosphere to protect the planet`s ozone layer. The exit of the HFC puts Australia in a strong position to meet its international obligations under the Montreal Protocol. At talks in Kigali, Rwanda, in October 2016, representatives of Australia and most of the other 196 countries parties to the protocol reached an agreement in which 85% of the world`s CFCs will expire. As a result of the international agreement, the hole in the Antarctic ozone layer is slowly recovering.  Climate forecasts indicate that the ozone layer will return to its 1980 level between 2050 and 2070.    The success of the Montreal Protocol is attributed to its effective burden-sharing and solution proposals, which have helped to mitigate regional conflicts of interest in relation to the inadequacies of the overall regulatory approach to the Kyoto Protocol.  However, global regulation was put in place before a scientific consensus was reached, and public opinion was convinced of the potential risks associated with the ozone layer.   The Fund is managed by an executive committee, similarly represented by seven industrialized countries and seven countries, pursuant to Article 5, elected annually by a meeting of the parties.
