World Ozone Day

Updated on

World Ozone Day or International Day for the Preservation of the Ozone Layer is observed on September 16th every year to create awareness regarding the Ozone Layer’s depletion. 

The Ozone layer has a huge role in preserving life on Earth. It is a fragile shield of gas which protects Earth from the sun’s harmful rays. On the occasion of World Ozone Day, talks and seminars are held across the globe trying to find possible solutions for preserving it.

Ozone Day

Montreal Protocol

The Montreal Protocol was signed on September 16, 1987. It is an international treaty for protecting the Ozone layer, by reducing the production of substances responsible for its depletion. Ever since then, a number of programmes have been held on this particular day in the Canadian city of Montreal. 

The International Day for the Preservation of the Ozone Layer was established by the United Nations General Assembly. It was celebrated for the first time in the year 1994. Educators across the globe save this day for raising awareness on the importance of Ozone layer among students. On this day, seminars and special events are held in schools worldwide.

What is an Ozone Layer?


The Ozone layer is composed of three atoms of Oxygen, represented by O3. Being a highly reactive gas, it is mostly found in the stratosphere and troposphere.

Chlorofluorocarbons (CFCs), halocarbon refrigerants, solvents and propellants are major causes for the depletion of the Ozone layer and the formation of the Ozone hole. Scientists have been observing a reduction in stratospheric ozone since the early 1970s and the polar regions have been the worst affected.

The hole in the Ozone layer allows harmful ultraviolet radiation to enter the Earth’s atmosphere which can prove deadly for the living beings on this planet. There are several ways in which we can contribute to the protection of the Ozone layer. This includes minimizing the use of vehicles, refrigerators, air coolers etc. For example, at times we can try to carpool with other people or use bicycles which is highly cost-effective and also helps in reducing pollution.

Hence, as responsible citizens, it becomes the duty of all of us to do our bit in preserving the precious Ozone layer. Developing and promoting eco-friendly practices is the key here. Educating the younger generation on the importance of reducing pollution and protecting the environment will ensure a better future!
