New Delhi: World Ozone Day, also known as International Day for the Preservation of the Ozone Layer, is observed every year on September 16.
What is the Ozone layer?
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.
World Ozone Day: History
As per the United Nations (UN), the scientific confirmation of the depletion of the ozone layer prompted the international community to establish a mechanism for cooperation to take action to protect the ozone layer.
This was formalized in the Vienna Convention for the protection of the Ozone Layer which was adopted and signed by 28 countries, on 22 March 1985.
In September 1987, this led to the drafting of The Montreal Protocol on Substances that Deplete the Ozone Layer.
In 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer.
The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge and technological information. It is structured around several groups of ozone-depleting substances.
World Ozone Day: Significance
World Ozone Day plays a significant role in highlighting the steps to protect the ozone layer. A united global effort to phase out ozone-depleting substances means that today, the hole in the ozone layer is healing, in turn protecting human health, economies and ecosystems.
The phaseout of controlled uses of ozone depleting substances and the related reductions have not only helped protect the ozone layer for this and future generations, but have also contributed significantly to global efforts to address climate change.
World Ozone Day 2021: Theme
This year, the theme of World Ozone Day is ‘Montreal Protocol – keeping us, our food and vaccines cool’.
As per UN, as this year’s World Ozone Day seeks to highlight, the Montreal Protocol does so much more – such as slowing climate change and helping to boost energy efficiency in the cooling sector, which contributes to food security.
