Savings estimates for the United States Environmental Protection Agency's ENERGY STAR voluntary product labeling program
ENERGY STAR is a voluntary energy efficiency-labeling program operated jointly by the United States Department of Energy and the United States Environmental Protection Agency (US EPA). Since the program's inception in 1992, ENERGY STAR has become a leading international brand for energy-efficient products. ENERGY STAR's central role in the development of regional, national, and international energy programs necessitates an open process whereby its program achievements to date as well as projected future savings are shared with committed stakeholders. Through 2006, US EPA'S ENERGY STAR labeled products saved 4.8Â EJ of primary energy and avoided 82Â TgÂ C equivalent. We project that US EPA'S ENERGY STAR labeled products will save 12.8Â EJ and avoid 203Â TgÂ C equivalent over the period 2007-2015. A sensitivity analysis examining two key inputs (carbon factor and ENERGY STAR unit sales) bounds the best estimate of carbon avoided between 54 and 107Â TgÂ C (1993-2006) and between 132 and 278Â TgÂ C (2007-2015).
