The Earth's ozone layer, a critical shield against harmful ultraviolet radiation, is steadily healing, according to a United Nations report released on World Ozone Day. The 2024 ozone hole shrank compared to recent years, marking progress in a decades-long global effort to reverse environmental damage.
Science-Driven Success Story
While natural atmospheric conditions contributed to 2024's smaller ozone hole, the World Meteorological Organization emphasized that sustained recovery stems from the Montreal Protocol. This landmark agreement, born from the 1985 Vienna Convention, phased out 99% of ozone-depleting chemicals used in refrigeration, aerosols, and industrial processes.
Health and Environmental Benefits
Full recovery to 1980s ozone levels is projected by mid-century, reducing risks of skin cancer, cataracts, and ecosystem disruption. UN Secretary-General António Guterres called this achievement "a testament to multilateral cooperation," urging continued adherence to science-based policies.
Asia's Role in Global Progress
The report highlights China's elimination of 628,000 tonnes of ozone-depleting substances since 2021, underscoring Asia's pivotal role in meeting Protocol targets. Such efforts align with broader regional commitments to sustainable development and green technology innovation.
