The California Air Resources Board recently approved first-in-the-nation rules to curb the impact of hydrofluorocarbon (HFC) refrigerants. HFCs are synthetic gases that are used in a variety of applications, but mainly to replace ozone-depleting substances in aerosols, foams, refrigeration and air-conditioning.
