The original Montreal Protocol, signed in 1987, was the first step in international action to protect stratospheric ozone. Under the original Montreal Agreement (1987), industrialized countries were required to begin gradually unblocking CFCs in 1993 and reduce consumption by 20% compared to 1986 by 1994 and by 50% by 1998. In addition, industrialized countries had to freeze their production and consumption of halons compared to 1986. Following the signing of the Montreal Protocol, new data caused more severe damage to the ozone layer than expected. We need all hands on deck to slow down and reverse global warming trends. The Montreal Protocol provides us with a good model for the future and shows a successful implementation of international environmental policy. While the Montreal Protocol is different from the Paris Agreement, we can only benefit from it if we study the success of the first agreement. There are two approaches to reducing F gas emissions. The first approach is to completely avoid the use of F gases by using gases or technologies that are less harmful to the climate. The second approach is to reduce the use of F gas in products and equipment.
For the first time in 2006, the EU defined specific strategies for reducing F gas emissions in 2006, with the 2006 F-gas regulation and a directive on the limitation of F gases used in motor vehicle air conditioning systems. In the absence of this legislation, F gas emissions are expected to increase (Figure 2, Orange Line). The annual meetings of the parties to the Montreal Protocol allow countries to verify, update and make decisions to improve compliance with the Montreal Protocol and the information base on which the parties rely. Australia is a member of important decision-making bodies under the protocol, including the executive committee that manages the Multilateral Fund. An active role allows Australia to have some influence on the nature and direction of global ozone protection issues. Australians also contribute to the various scientific and technical bodies of the Montreal Protocol. Scientific and technical groups provide the parties with new information to support decision-making in the Montreal Protocol. The Vienna Convention on the Protection of the Ozone Layer, adopted in 1985, was the precursor to the Montreal Protocol. The Vienna Convention is often referred to as the Framework Convention because it has served as a framework for efforts to protect the world`s ozone layer. The Vienna Convention did not require countries to take concrete steps to combat ozone-depleting substances. Instead, in accordance with the provisions of the convention, countries around the world have agreed on the Montreal Protocol on ozone-depleting substances under the convention in order to advance this goal. “We call it a “pause” because poleward traffic trends could continue, stay flat or stay upside down,” Banerjee said. It is the struggle between the opposite effects of ozone recovery and the increase in greenhouse gases that will determine future trends. The magnitude of this benefit is considerable.
