World Ozone Day 2021: World Ozone Day, also known as International Day is observed every year on September 16 to commemorate the signing of the Montreal Protocol.
- It is celebrated to spread awareness among people about the depletion of the Ozone Layer and search for possible solutions to preserve it.
The theme of World Ozone Day 2021:
- The theme for International Day for the Preservation of the Ozone Layer fot the year 2021 is Montreal Protocol – ‘Keeping us, our food and vaccines cool.’
- In order to keep in check on substances that deplete the Ozone layer, a deal named Montreal Protocol was signed by almost every country on September 16, 1987 and subsequently, in 1994, the Montreal Protocol proclaimed this day as the World Ozone Day.
World Ozone Day 2021 in India:
- India observed the 27th Global Ozone Day this year.

About the Montreal Protocol:
- The Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol) is an international agreement made on 16th September, 1987, where countries from across the globe decided to curb substances such as:
- It was designed to stop the production and import of ozone depleting substances and reduce their concentration in the atmosphere to help protect the earth’s ozone layer.
- These substances are widely used for cooling and refrigerating purposes.
- As a result of the usage of these harmful substances, a hole in the ozone layers in Antarctica was discovered back in 1970.
- This ultimately led to acute global warming in the past 20 years.
- According to the World Meteorological Organization, the Antarctic hole caused by Ozone-depletion was finally closed as a result of the collaborative efforts by these countries.
About Ozone Layer:
- The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation.
- Life is not possible on Earth without the ozone layer.
- It contains a high concentration of ozone in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
- Sunlight makes life, but the ozone layer creates life as we know it today.
- It protects life on Earth by absorbing Sun’s harmful ultraviolet radiation and so is also known as Ozone Shield.
- Ultraviolet rays can cause several skin diseases.
