International Agreement To Limit Cfc Production

In 1997, it was reported that in Russia in the 1990s, a large production of CFCs was sold to the EU on the black market. Production and consumption in the United States have been made possible by fraudulent reports due to poor enforcement mechanisms. Similar illegal markets for CFCs have been identified in Taiwan, Korea and Hong Kong. [49] Under the Montreal Protocol on Ozone Depleting Substances, including the Executive Committee (ExCom) 53/37 and ExCom 54/39, the parties to this protocol agreed to set 2013 as the date for freezing the consumption and production of CFCs for developing countries. In industrialized countries, consumption and production of HCFCs began to decline in 2004 and 2010 respectively, with a 100% reduction in 2020. Developing countries have agreed to begin reducing consumption and production of CFCs by 2015, with a 100% reduction in 2030. [23] The original Montreal Protocol, signed in 1987, was the first step in international efforts 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. In the 1970s and 1980s, there was growing international concern that SO was harming the ozone layer.

In 1985, international cooperation in this area was formalized by the Vienna Convention on the Protection of the Ozone Layer. This cooperation led to the signing in 1987 of the Montreal Protocol on ozone-depleting substances. Many Australian experts have been recognized for their contributions to the implementation of the Montreal Protocol, for their work in assisting Australia in meeting its phasing-out obligations, and for their international contribution to the gradual use of ozone-depleting substances. The Montreal Protocol controls the production and consumption of specific chemicals, which have no value: CFCs, halons, fully halogenated HCFC (HCFC), methyl bromide and other similar chemicals. It sets concrete reduction targets and a timetable. The protocol originally required parts other than developing countries to reduce consumption and production of CFCs to 1986 (basisk), 20% and then an additional 30% by 1999 and to freeze halon consumption at 1986 levels.
