Ozone: A small step towards righting our wrongs
A whopping 99 per cent of the banned ozone-depleting substances have been phased-out, reveals the UN-backed Scientifc Assessment of Ozone Depletion: 2022. This positive outcome is the result of the Montreal Protocol, an international treaty designated to protect the ozone layer that was agreed upon back in 1987. The report also highlights that if current policies remain intact, the ozone layer is expected to recover to 1980 values (before the appearance of the ozone hole) by around 2066 over the Antarctic, by 2045 over the Arctic and by 2040 for the rest of the world.
