‘Perhaps the single most successful international agreement to date has been the Montreal Protocol.’ Kofi Annan was not wrong to say this.
The Montreal Protocol is indeed a success story. The ozone hole in Antarctica is slowly recovering and is expected to reach the 1980 levels between 2050 and 2070.
The Montreal Protocol phases down both the production and use of nearly a hundred harmful chemicals. This is done in several steps. The developed and developing countries follow a different timetable in the process.
Without this treaty, ozone layer depletion would have increased at least by ten times by 2050 in comparison with the current levels. This treaty also aids the global climate system.
