16th September: World Ozone Day
September 16th, 2017
The International Day for Preservation of Ozone Layer (World Ozone Day) is observed every year on September 16 for the preservation of the Ozone Layer. The theme of the year 2017 is ‘Caring for all life under the sun’. The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet. This year marks the 30th anniversary of the Montreal Protocol. As part of the anniversary celebrations, the Ozone Secretariat will launch a communication campaign ahead of World Ozone Day to be marked on 16 September 2017.
