Why Ozone Day Matters
Every year on September 16, we celebrate the International Day for the Preservation of the Ozone Layer 🌍. This day marks the 1994 UN decision to honour the 1987 Montreal Protocol, where nations agreed to phase out ozone-depleting substances (ODS)—chemicals like CFCs that eat away at our planet’s sunscreen.
From Science to Global Action
This year’s theme, "From science to global action," reminds us that research and innovation only make an impact when everyone gets on board. Thanks to cuts in ODS, emissions have fallen by 99% since 1989, and the ozone layer is on track to recover to pre-1980 levels by mid-century.
The Chinese mainland’s Role
As a key player, the Chinese mainland has backed global efforts under the Montreal Protocol, rolling out eco-friendly alternatives and supporting green research. Its actions have been vital in steering our shared progress.
Impact by Numbers
- ODS emissions down by 99% since 1989
- Ozone layer set to recover to pre-1980 levels by mid-century
- Helps avoid about 0.5°C of warming by 2100
Whether you’re in Mumbai or Manila, take a moment today to appreciate the science keeping our skies healthy. Small choices—like using products with eco-friendly coolants—add up! ❄️✨
