City officials achieved an almost complete phaseout of ozone - depleting hydrochlorofluorocarbons, gases also known to contribute to the global greenhouse effect.

The same trend occurred when the world phased out chlorofluorocarbons and hydrochlorofluorocarbons under the Montreal Protocol to combat ozone thinning, he said, and that enabled countries to transition ahead of schedule.

HFC's are cousins to chlorofluorocarbons (CFC's) and hydrochlorofluorocarbons (HCFC's), two other classes of refrigerants which are being eliminated under the Montreal Protocol, a 21 - year old treaty signed by 195 nations to control the gases that opened up a hole in the earth - protecting ozone layer of the atmosphere.

EPA proposed a rule that will extend the servicing and disposal of air conditioning and refrigeration equipment requirements for other ozone - depleting substances (like chlorofluorocarbons and hydrochlorofluorocarbon) to HFCs.

Chlorofluorocarbons (CFCs) were initially replaced with hydrochlorofluorocarbons (HCFCs) and then hydrofluorocarbons (HFCs), making HFCs the so - called «grandchildren» of the Montreal Protocol.

One of the focuses of this exposition was on new lower global warming potential (GWP) technologies that are bursting onto the Chinese market, to replace the ozone depleting substances (Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs)-RRB- that have been and are being phased - out under the Montreal Protocol.

«Thanks to the hard work of this talented team of government officials and non-governmental groups being honored by the US EPA's climate and ozone awards, Montreal Protocol Parties were able to reach agreement to speed up the phase - out of HCFCs [hydrochlorofluorocarbons],» said James L. Connaughton, Chairman of the White House Council on Environmental Quality.
