The International Day for the Preservation of the Ozone Layer 2024 is celebrated worldwide on 16th September. This day, also known as World Ozone Day, raises global awareness about the importance of the ozone layer in protecting the Earth from harmful ultraviolet (UV) rays.
Observing this day encourages action to prevent ozone depletion, which significantly contributes to global warming and climate change.
What is the International Day for the Preservation of the Ozone Layer?
- Annually observed on 16th September, this day serves as a reminder of the urgent need to protect the ozone layer from harmful substances.
- Initiated by the United Nations (UN), it promotes actions to mitigate ozone depletion, which affects climate and human health.
Key Highlights of 2024 Observance:
- Date: 16th September 2024
- Occasion: 30th observance of the International Day for the Preservation of the Ozone Layer
- Theme: “Montreal Protocol: Advancing Climate Actions”
This year’s theme emphasizes the Montreal Protocol’s continued mission to safeguard not only the stratospheric ozone layer but also to promote climate action by reducing the use of ozone-depleting substances (ODS).

The choice of 16 September is symbolic as it commemorates the signing of the Montreal Protocol in 1987, which is a crucial treaty aimed at regulating the production and consumption of ozone-depleting substances (ODS). This international agreement has significantly contributed to ozone layer protection, making the International Day for the Preservation of the Ozone Layer a momentous annual event.
Understanding the Ozone Layer:
- What is Ozone?
Ozone (O3) is a highly reactive gas found mostly in the stratosphere. About 90% of atmospheric ozone resides in this layer, where it plays the vital role of absorbing harmful UV radiation from the sun. This protective layer is often referred to as the “good ozone.” - The Ozone Hole
Contrary to the term, the “ozone hole” is not an actual hole but rather an area of severe ozone depletion, most commonly found above the Antarctic region. It’s caused by the buildup of chemicals such as CFCs (Chlorofluorocarbons), which damage the ozone molecules.
The Montreal Protocol:
The Montreal Protocol on Substances that Deplete the Ozone Layer is considered one of the most successful environmental treaties, with universal ratification by all UN member states. Since its enforcement, global consumption of ozone-depleting substances has been reduced by about 99%, saving millions of lives from harmful UV exposure.
India’s Contributions and Achievements:
- Indian Cooling Action Plan (ICAP):
India has made substantial progress in phasing out CFCs and is working toward eliminating these harmful substances by 2037-38. The government also focuses on adopting low-GWP (Global Warming Potential) alternatives, particularly in the transport and refrigeration sectors. - ODS (Regulation and Control) Rules, 2000:
India’s efforts to eliminate CFCs and halons in equipment began as early as 2003, achieving significant reductions ahead of the global schedule.
2024 Events in India:
The Ministry of Environment, Forest and Climate Change (MoEFCC) will be organizing a key event in New Delhi on 16 September 2024 to commemorate the International Day for the Preservation of the Ozone Layer. Attendees include prominent figures from the UN Environment Programme (UNEP) and other environmental bodies.
- Event Highlights:
- Announcement of winners for national-level poster and slogan competitions
- Release of key documents such as India’s Success Story under the Montreal Protocol and the Action Plan for the Indian Cooling Action Plan (ICAP)
The Future of Ozone Recovery:
The World Meteorological Organization (WMO) reports that the ozone layer is on track to recover to 1980 levels by 2066 in Antarctica, 2045 in the Arctic, and 2040 for the rest of the world. The latest WMO Ozone and UV Bulletin 2024 mentions how meteorological factors and volcanic activity in 2023 influenced the Antarctic ozone hole, though recovery efforts continue globally.
Conclusion:
The International Day for the Preservation of the Ozone Layer 2024 serves as a powerful reminder of the crucial role the Montreal Protocol has played in safeguarding our planet. On 16 September 2024, let’s unite globally to reaffirm our commitment to protecting the ozone layer and taking strong climate actions for a healthier future.
