Certainly! World Ozone Day, also known as the International Day for the Preservation of the Ozone Layer, is observed annually on September 16. The purpose of this day is to raise awareness about ozone layer depletion and explore solutions to preserve it²⁴.
On World Ozone Day in 2023, we celebrate the remarkable achievements of the Montreal Protocol on Substances that Deplete the Ozone Layer. This international treaty has played a crucial role in fixing the ozone layer and reducing climate change. Here are some key points:
- Ozone Layer Recovery:
- The latest update from the Scientific Assessment Panel to the Montreal Protocol confirms that ozone layer recovery is on track.
- Ozone levels are expected to return to 1980 levels by around 2066 over the Antarctic.
- By banning ozone-depleting substances, the treaty allows the ozone layer to slowly recover, protecting millions of people from skin cancer and eye cataracts.
- Climate Impact:
- Many ozone-depleting substances were also climate-warming gases.
- The Montreal Protocol’s efforts have contributed to slowing down climate change.
- Kigali Amendment:
- The Kigali Amendment aims to phase down the production and consumption of hydrofluorocarbons (HFCs).
- HFCs replaced ozone-depleting substances in the cooling industry.
- Universal ratification and full implementation of the Kigali Amendment are crucial.
- Sustainable cooling solutions are essential for meeting development goals while minimizing climate impact.
- Impact and Theme:
- The Montreal Protocol continues to protect human health, nature, and the climate.
- The theme for the 2023 International Day for the Preservation of the Ozone Layer is “Montreal Protocol: fixing the ozone layer and reducing climate change”¹³.
Let’s continue our efforts to safeguard the ozone layer and create a sustainable future! 🌍🌿🌞
