UN: In 1994, the UN General Assembly announced September 16 as the International Day for the Preservation of the Ozone Layer. The day is remembered for the date of the 1987 signing of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114). The Montreal Protocol’s main objective is to protect the ozone layer by introducing initiatives that will be helpful in reducing global consumption and production of harmful bodies that damage the ozone layer.
The ozone layer is the most crucial part of Earth’s atmosphere that works as a shield, keeping out potentially harmful ultraviolet radiation. Every year, September 16 is celebrated with the ultimate belief that together, we will work for the elimination of these harmful substances by implementing policies and adopting new scientific and technological methods.
Chlorofluorocarbons, or CFCs, are the substance that has the most impact on the ozone layer. This harmful substance can be found in many different products, such as aerosol cans and freezers. This triggers ozone depletion in the atmosphere.
Because of this, the ozone layer above the Antarctic has developed several holes during every southern hemisphere winter/spring season. Thus, it affects the overall atmosphere of the Earth and brings many other serious health threats.
A recent study also estimated that without the Montreal Protocol ban on CFCs, less carbon would have been absorbed and stored in plants, vegetation, and soil – Earth’s carbon sink – which might have led to an additional increase of 0.5 – 1ºC of global warming.
“In the face of a triple planetary crisis of climate change, nature loss, and pollution, the Montreal Protocol is one of the best examples we have of the power of multilateralism; how global cooperation can protect life on Earth, which is the theme of this year’s World Ozone Day 35th anniversary,” stated Meg Seki, Executive Secretary of the United Nations Environment Programme’s (UNEP’s) Ozone Secretariat.
As the world is becoming hotter daily, it is high time we adopt nature-friendly policies and technologies. On this World Ozone Day, let’s remember the achievements of the Montreal Protocol: the Protocol that protected all living things, now and into the future, through global cooperation.
