Background The Montreal Protocol On Substances That Deplete The Ozone The worldwide recognition of cfcs’ detrimental effects prompted the enactment of the montreal protocol in 1987, a treaty aimed at phasing out the production of ozone depleting substances. Originally signed in montreal by 24 countries, including canada, the montreal protocol is regarded as one of the most successful multilateral agreements. it has achieved the elimination of the large majority of ods and, as a result, the ozone layer is on a path to recovery.
Protecting The Ozone Layer Through International Cooperation An The montreal protocol has been rapidly responsive to evolving science and has sought to deliver its benefits to low income countries. it has protected the ozone layer and climate by phasing. In the 1970s, evidence began to surface that cfcs, which were used in everyday household products such as air conditioners and refrigerators, were depleting the earth’s protective ozone layer and increasing the level of ultraviolet radiation reaching our planet’s surface. With the full and sustained implementation of the montreal protocol, the ozone layer is projected to recover by the middle of this century. without this treaty, ozone depletion would have increased tenfold by 2050 compared to current levels, and resulted in millions of additional cases of melanoma, other cancers and eye cataracts. Thanks to the montreal protocol, drawn up in 1987, almost 200 countries have now agreed to phase out many ozone depleting substances such as cfcs.
Lessons From The Montreal Protocol Pdf Ozone Depletion With the full and sustained implementation of the montreal protocol, the ozone layer is projected to recover by the middle of this century. without this treaty, ozone depletion would have increased tenfold by 2050 compared to current levels, and resulted in millions of additional cases of melanoma, other cancers and eye cataracts. Thanks to the montreal protocol, drawn up in 1987, almost 200 countries have now agreed to phase out many ozone depleting substances such as cfcs. By banning new production and use of cfcs, the montreal protocol eliminated a significant contributor to climate change, avoiding a potential additional global temperature increase of 0.5 to 1 degree fahrenheit by 2100. As a result of the montreal protocol, the total abundance of ozone depleting gases in the atmosphere has begun to decrease in recent years. if all countries that have signed the protocol maintain their commitments, the decrease of ods in the atmosphere will continue through the 21st century. The montreal protocol on substances that deplete the ozone layer[2] is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. To mitigate the threats to future ozone recovery, it is crucial to ensure that the montreal protocol and its amendments continue to be implemented effectively in order to have firm control.
