The United Nations’ International Day for the Preservation of the Ozone Layer is celebrated on the 16th September every year. Commemorating the 1987 signing of the Montreal Protocol on Substances that Deplete the Ozone Layer, the day advocates activities that create awareness on topics related to climate change and ozone depletion.

The theme of World Ozone Day 2019 is '32 years and Healing'. This year's theme celebrates three decades of remarkable international cooperation to protect the Ozone Layer and the climate under the Montreal Protocol. It also reminds the people to keep up the momentum to ensure healthy people and a healthy planet. In 2018, the latest Scientific Assessment of Ozone Depletion was completed. This assessment shows that the parts of the Ozone Layer have recovered at a rate of 1-3% per decade since 2000. Even at the protected rates, Northern hemisphere and mid-latitude ozone will heal completely by the 2030s. The Southern Hemisphere will follow in the 2050s and Polar Regions by 2060. No doubt Ozone Layer protection efforts also contribute in fighting with the climate change.

The day was celebrated at Sherubling Central School with teachers and Students. The following activities were conducted to observe the day:

1. Essay writing competition based on the Theme
2. Drawing competition 
3. Quiz
