Islamabad - Pakistan is part of the global efforts to save ozone layer for sustainability of the earth, said National Programme Manager of the Ozone Protection Initiative of the Ministry of Climate Change, Mazhar Hayat on Saturday.

“It is heartening to observe that Pakistan is very much on the track to eliminate the use of Ozone depleting substances and is in full compliance with the targets set-out by the Ozone Secretariat,” he said this talking to media persons here.

In January this year, he said, Pakistan had achieved the 10 per cent reduction target of Hydrochlorofluorocarbons (HCFCs).

He said all-out efforts would be made to completely restore the ozone layer to its 1980-level by the middle of the century, which was inevitable for sustainability of earth and the life on it.

He emphasized that controlling emission of ozone layer-cracking gases, mostly in refrigerators and air-conditioners was need of the hour to protect earth’s health and sustainability.

“Use of ozone-depleting gases such as chlorofluorocarbons (CFCs) had cracked a hole in the ozone layer that protects us from the sun’s harmful ultraviolet radiation.

But thanks to global community’s role, the ozone-depletion problem has been substantially addressed,” he added.

Depletion of Ozone Layer, he said, was one of the most serious environmental concerns threatening the very existence of life on earth.

Ozone provides a natural protective filter against harmful ultra-violet rays from the sun, which can cause sunburn, cataracts and skin cancer as well as damage vegetation.

“Thirty years ago, the international community had signed the Vienna Convention for the Protection of the Ozone Layer. Under its Montreal Protocol, a global treaty passed in 1987 to phase out ozone depleting substances like chlorofluorocarbons (commonly found in spray cans and refrigerants at the time), ozone depletion has stopped. However, the world is on track to completely restore the ozone layer,” he said.

The Montreal Protocol has, in fact, established a unique partnership between the developed and developing countries, all striving in unison and harmony to achieve the phase out of Ozone depletion Substances (ODS), Hayat said.

“Protection of ozone layer, the ultimate objective of the Montreal Protocol on Substances that deplete the ozone layer, is must to allow the life on earth to prosper in a sustainable manner.

Looking back over the past 30 years, we are at a critical juncture in the implementation of a phase out programme for the Ozone Depleting Substances,” he underlined.
