Montreal Protocol

« Back to Glossary Index

The Montreal Protocol is the landmark multilateral environmental agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone-depleting substances (ODS) and Hydrochlorofluorocarbons (HCFCs). When these ODS and HCFs are released into the atmosphere they damage the stratospheric ozone layer. Ozone is the earth’s protective layer that protects humans and the environment from harmful ultraviolet radiation from the sun.

Montreal Protocol was adopted on 16 September 1987.

This is one of the successful treaties because after that Ozone layer started recovering. Ozone recovery saves around 2 million people each year from skin cancers. 

It is estimated that, if the world would have not acted on time, ozone depletion would have increased by more than ten times by 2050, as compared to what we have today.
