The Montreal Protocol has been recognized as the most successful international environmental treaty in history. It has been universally ratified and all the 197 countries of the world are Parties to the Vienna Convention and its Montreal Protocol. In the 27 years of its operation with extraordinary international cooperation under the treaty has led to phase-out of production and consumption of several major Ozone Depleting Substances (ODSs) such as Chlorofluorocarbons (CFCs), Carbontetrachloride (CTC) and halons globally from 1st January, 2010. The Montreal Protocol has not only contributed to protect the ozone layer but also has reduced Green House Gas (GHG) emissions by about 11 Giga tonnes CO2 equivalent per year through its ODS phase-out activities so far.
