Countries called for the elimination of HCFC-22 to harm the ozone layer

Many countries, such as small Pacific island nations, rich or developing countries, have teamed up to withdraw from the market of HCFC-22, a hydrochlorofluorocarbure that is harmful to the ozone layer on the floor. pacifier.

This proposal was made by the United States, Argentina, Brazil, Mauritania, Federated States of Micronesia, Maurice Island, Switzerland, Norway, Iceland and Palau and will be discussed in September at an international conference held in Montreal (Canada), marking the 20th anniversary of the signing of the Protocol on ozone depleting substances.

Air conditioning system in China

In 1987, the signatories to the Montreal Protocol did not anticipate an economic boom in Asia and an increase in the production of air conditioning systems in China and India. Lower machinery prices and air conditioning systems are increasingly being used by the average class in newly developed countries. As a result, in recent years, the consumption of HCF-22 has increased by more than 30% annually in India and China.

The current economic development threatens the recovery of the ozone layer. According to the World Meteorological Organization, this recovery will last longer than expected.

HCF-22 is both a substance harmful to the ozone layer and a greenhouse gas. It poses a potential risk of warming climate 100 to 600 times higher than carbon dioxide.
