The 30-year-old ozone layer treaty has a new role: fighting climate change
The 1987 treaty that stopped the pollution causing a hole in the ozone layer is rightly seen as a major success story. It’s arguably the most successful international environmental agreement ever. It’s true that, 30 years on from the signing of the Montreal Protocol, the Antarctic ozone hole still reappears every year. Yet the protocol really is working and its continued development means that it is doing more good than ever, including helping the fight against climate change.
