Rays of Hope: Successful Reduction of Ozone-Depleting HCFCs | Science-Environment

Bristol, Jun 12 (The Conversation) - Since the discovery of a hole in the ozone layer in 1985, nations have rallied to reverse the damage. The standout measure, the Montreal Protocol, has earned recognition as the most effective environmental treaty ever.

Adopted in 1987 and ratified by every UN member state, the protocol aimed to curb the release of ozone-depleting substances, notably CFCs. Starting in 1989, it gradually eliminated the production of these chemicals, allowing time for economies to adjust and providing financial support for regulatory compliance.

Recent research has shown a decline in atmospheric HCFC levels since 2021, surpassing previous scientific expectations. This milestone underscores the Montreal Protocol's success in addressing both CFCs and their less harmful successors, offering a rare triumph in the fight against climate-warming gases.
