Jan. 24, 2006: Refrigerator Manufacturers Join EPA Program To Cut Emissions
WASHINGTON - The U.S. Environmental Protection Agency (EPA) and the Association of Home Appliance Manufacturers (AHAM) have launched a new, voluntarily program to reduce hydrofluorocarbon (HFC) emissions from the refrigeration and insulation used in making new refrigerators and freezers. Once implemented, the program is expected to significantly reduce HFC emissions in the manufacturing of 12 million refrigerator-freezers in the United States and more than 60 million worldwide each year.
HFCs are used in refrigerators and freezers in two ways - as the refrigerant and as a "blowing agent" for the insulation foam within the cabinet walls. HFCs have become widely used as substitutes for chlorofluorocarbons and other ozone-depleting chemicals that have been phased out. While HFCs do not harm the stratospheric ozone layer, when released to the atmosphere, they are potent greenhouse gases - up to 1,300 times more potent than carbon dioxide.
