Kyoto ProtocolLegislation Regarding The Control of Greenhouse Gases in HKGreenhouse Gases in Hong Kong and ChinaClimate Change and Air PollutionThe United Nations Framework Convention on Climate Change and its Kyoto Protocol was extended to Hong Kong with effect from 5 May 2003. The Kyoto Protocol is directed at the reduction of four greenhouse gases (carbon dioxide, methane, nitrous oxide, sulphur hexafluoride) and two groups of gases (hydrofluorocarbons, perfluorocarbons).See more on hiki-air.fandomHome | ECO-CM (Embodied Carbon Of Construction Materials) cejcheng.people.ust.hk/ecThe main GHGs are carbon dioxide, methane, nitrous oxide, ozone and artificial chemicals called halocarbons (CFCs, HFCs, PFCs) and other long-lived gases such as sulfur hexafluoride (insulating gas). These GHGs block the infrared radiation from escaping the earth surface and, hence, rising the surface temperature of the earth. This is known as the
