International Day for the Preservation of the Ozone Layer: 16 September 2019

Date: 
Mon 16/09/19

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 ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the sun's rays, thus helping to preserve life on the planet. As such, it is paramount that we protect the ozone layer from harmful substances such as HCFCs (hydrochlorofluorocarbons), which are both ozone-depleting substances and powerful greenhouse gases that contribute to the thinning of the ozone layer. Nearly 2,000 times more potent than carbon dioxide in adding to global warming, the successful reduction of HCFC emissions remains one of the UN’s greatest challenges.

However, the gradual phasing out of controlled uses of ozone-depleting substances has not only helped protect the ozone layer for this and future generations, but has also contributed significantly to global efforts to address climate change. As a result, it has protected human health and ecosystems by limiting the harmful ultraviolet radiation from reaching Earth.

The theme for 2018 was “Keep Cool and Carry on: The Montreal Protocol”, which was a motivational rallying call urging all of us to carry on with the exemplary work of protecting the ozone layer and the climate under the Montreal Protocol. The theme had two connotations – that our work of protecting the ozone layer also protects climate and that the Montreal Protocol is a “cool” treaty, as exemplified by its outstanding success.

The 2019 theme for the International Day for the Preservation of the Ozone Layer has not yet been announced. This page will be updated as more details are made available.
