Iran ahead of schedule in preserving ozone layer
TEHRAN – Iran was committed to reducing ozone-depleting substances by 35 percent by the beginning of 2022, which is currently ahead of schedule reaching 67 percent.
According to the schedule of the Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol), Iran has been able to fulfil its obligations and remove 9,800 tons of ozone-depleting substances from the consumption cycle, which has caused the emergence of technologies compatible with the ozone layer in 1,378 production and service units.
The Public Ozone Layer Security Plan has been one of the spearheading plans in the battle against the obliteration of the ozone layer. Up toWorld Ozone Day is praised consistently on September 16 as a recognition for the marking of the Montreal Convention. It was on this date in 1987 when this convention was agreed upon.onvention and the Assembled Countries.
Despite sanctions, Iran is among the leading countries in the field of expanding regional cooperation to use local capabilities to manage and remove substances that destroy the ozone layer, and control the trade of materials and goods containing these substances.
World Ozone Day is praised consistently on September 16 as a recognition for the marking of the Montreal Convention. It was on this date in 1987 when this convention was agreed upon.
The theme for the 2022 International Day for the Preservation of the Ozone Layer, is “Montreal Protocol@35: global cooperation protecting life on earth”.
The theme recognizes the wider impact the Montreal Protocol has on climate change and the need to act in collaboration, forge partnerships and develop global cooperation to address climate challenges and protect life on earth for future generations.
The ozone layer is of great importance for sustaining life on earth, if harmful emissions are reduced enough, it will take about 50 years for the ozone layer to repair so it requires global attention and action.
34 years ago, the use of harmful man-made chemicals began eating away at the ozone, the hole over Antarctica was first discovered by the British Antarctic Survey in 1985.
The ozone layer is a part of the atmosphere that has high concentrations of ozone (a gas made of three oxygen atoms O3), compared to oxygen molecules that exist in nature as a pair of oxygen atoms. It exists 10km to 40km above the surface of the earth in a region called the stratosphere and contains 90 percent of all the ozone in the atmosphere.
Some harmful gasses including HCFC and Chlorofluorocarbons (CFCs) can interfere with the formation of ozone; mostly causing gaps or holes in the layer, as well as passing UV radiation from the sun to the atmosphere.
CFCs are referred to compounds of carbon, hydrogen, chlorine, and fluorine typically gases used in refrigerants and aerosol propellants. They are harmful to the ozone layer in the earth’s atmosphere owing to the release of chlorine atoms on exposure to ultraviolet radiation.
HCFCs are additionally man-made compounds containing hydrogen, chlorine, fluorine, and carbon and don’t happen normally anyplace. These compounds are used in refrigeration, aerosol propellants, foam manufacture, and air conditioning.
HCFCs are less dangerous causing a smaller risk to the ozone layer; while being very powerful greenhouse gases, which are nearly 2,000 times more potent than carbon dioxide in adding to global warming.
Ozone hole shrinking
The ozone hole which was once the major environmental concern turned into the least important concern today; as the concentration of harmful emissions has considerably reduced by 14 percent since 2000.
The hole has been shrinking by 1-3 percent a decade.
However, the upper ozone layer above the Northern Hemisphere is said to be completely repaired in the 2030s, and the gaping Antarctic ozone hole should disappear in the 2060s, according to a scientific assessment released in 2018 at a conference in Quito, Ecuador.
As per the UN, endeavors to safeguard the ozone layer have likewise assisted with handling environmental change by forestalling the arrival of around 135 billion tons of carbon dioxide beginning around 2010.
By the end of the century, eradicating HCFCs emissions not only can lead to the ozone layer repair but to reduce the temperature raise up to 0.4°C.
