The depletion of the ozone layer in the stratosphere of the atmosphere surrounding the Earth still poses a serious problem.
According to data available, the hole in the ozone layer in the South Pole, which began to increase rapidly from the early August of 2021, expanded into an area of 24.8 million square kilometres by October 7 that year.
Ozone depletion in the Antarctic and the Arctic is attributable to the existence of huge amounts of air pollutants. The artificially-emitted pollutants existing in the atmosphere for scores of years deplete ozone, resulting in thinning its layer or making a hole there.
Ozone depletion exerts a serious impact on climate change. In 2020, heat waves swept Antarctica, known as the coldest place on the Earth, for the first time. At that time experts claimed that the expansion of the ozone hole over the South Pole caused the phenomenon.
In view of the importance of preserving the ozone layer, the international community set this year’s theme of World Ozone Day as “Montreal Protocol: fixing the ozone layer and reducing climate change.”
Today, preservation of the ozone layer arises as a very urgent and important undertaking to be uninterruptedly conducted by the concerted efforts of the international community, not by a few countries.
The DPRK acceded to the Vienna Convention for the Protection of Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer in 1995, and the Kigali Amendment to the Montreal Protocol in 2017, and has made efforts to implement the international conventions.
It has revised and supplemented laws and regulations, including the Law of the DPRK on Prevention of Air Pollution, several times, and ensured that industrial establishments, units and citizens minimized the production, import, sale and use of ozone layer-depleting substances and the facilities or goods containing them.
It conducts diverse activities to solve technical problems arising in the selection and use of refrigerants and introduce science and technology conducive to the protection of the ozone layer and prevention of global warming.
It also raises public awareness of the protection of the ozone layer and climate change by means of the mass media.
