The Ministry of Environment and United Nations Environment Programme on Tuesday organised a national consultation workshop to manage a gradual phase-out of the use of hydrochloro-fluorocarbons (HCFCs) in order to protect the ozone layer. Speaking at the workshop, Khieu Muth, secretary of state at the Ministry of Environment, said the country’s phase-out of chlorofluorocarbons (CFCs) ended successfully in 2009 and that the Kingdom would aim to be HCFC-free by 2040. Cambodia currently imports HCFC-22 from China, India, Malaysia and Singapore for use only in refrigeration and air-conditioning equipment, he said.
