Ozone Layer 'Healing', on Track to Recover by Mid-Century, UN Says
The Antarctic ozone hole's shrinkage reflects global efforts phasing out over 99% of ozone-depleting substances, with full recovery expected by mid-century, reducing UV-related health risks.
- On September 16, 2025, the United Nations and the World Meteorological Organization released the Ozone Bulletin 2024, noting that the Antarctic ozone hole was reduced in size compared to previous years.
- This improvement follows decades of international efforts beginning with the 1975 Vienna Convention and the 1987 Montreal Protocol that targeted phasing out ozone-depleting substances widely used in refrigeration and aerosol sprays.
- The bulletin reported that in September 2024, the Antarctic ozone hole developed more slowly and showed delayed depletion, reaching a peak deficit equivalent to 46.1 million tonnes less ozone than the 1990–2020 average, signaling early signs of the ozone layer’s recovery.
- UN Secretary-General Antonio Guterres stated, "The ozone layer is healing today," and WMO Secretary-General Celeste Saulo noted, "This is no coincidence," reflecting the success of global cooperation and scientific guidance.
- If current regulations continue unchanged, the ozone layer is expected to return to its 1980 levels by around 2066 over Antarctica, which could lead to a decrease in UV-related health issues and environmental harm globally.
