Our analysis shows that even if the spirit, as well as the letter, of the Montreal Protocol is fully adhered to, under the present terms of the Montreal Protocol, the ozone layer will not recover until around 2040. At the same time, the Greenpeace calculations show that an emergency phase out of ozone depleting substances, including early phase out of HCFCs and methyl bromide, could accelerate recovery of the ozone layer by nearly fifteen years (to 2026) and this would reduce ozone depletion by nearly 40%.
