ozone depletion — Ozone depletion The Antarctic ozone hole reaches its maximum extent in October of each year. On October 7, 2021, when this image was captured, the Antarctic ozone hole spanned 24.8 million square km (9.6 million square miles).

Under the Montreal Protocol, developed countries successfully phased out the production and consumption of chlorofluorocarbons (CFCs) by 1996.12

While some countries began banning CFC-based aerosols as early as the late 1970s, the international effort to eliminate these substances was formalized through the 1987 treaty. The phase-out schedules were established to protect the ozone layer, which shields Earth from harmful ultraviolet radiation.12

Other ozone-depleting chemicals followed different timelines:
* Halons: Phased out in developed countries by 1994.1
* Methyl bromide: Eliminated in developed countries by 2005.1
* HCFCs: Scheduled for complete phase-out in developed countries by 2030.12

It is a fundamental ethical imperative to protect the global environment for future generations, and the successful implementation of these phase-outs demonstrates the effectiveness of international cooperation in addressing critical ecological threats.1
