Minister of Environment Say Samal has called on ministries, institutions and stakeholders to continue to implement the Montreal Protocol on substances that deplete the ozone layer and to do it more comprehensively.

The Montreal Protocol is an international treaty designed to protect the ozone layer by ending the production of substances that cause ozone depletion, which is an issue related to the climate but distinct from climate change.

The substances in question are mainly chlorofluorocarbons or CFCs along with HCFCs and HFCs, all of which are used in refrigeration, aerosol propellants, foam manufacture and air conditioning.

He said that there is still more work needed to be done to raise public awareness and encourage consumers to pay attention to stopping the use of certain chemicals that deplete the ozone layer.

“We need to prepare other regulations to better achieve this change, including improving standard building codes, energy efficiency and cooling technology solutions with high energy efficiency,” he said in September 16 a letter celebrating World Ozone Day.

He described the celebration of World Ozone Day as a meaningful event, saying that the event had raised public awareness of the need for and importance of participating in the protection of the ozone layer of the atmosphere, which protects the planet from dangerous radiation.

He said he believed that through the active participation of all nations, the ozone layer may return to its original state by the middle of the 21st century.

“I would like to call on all ministries, institutions and stakeholders, especially those who conduct businesses concerning the use of substances that deplete the ozone layer like refrigerant substances, to continue to pay more attention to the successful implementation of standard documents relating to the Montreal Protocol on substances that deplete the ozone layer,” the letter read.
