Abstract

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 (EPA). Since the program 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, EPA'S ENERGY STAR labeled products saved 4.9 exajoules (EJ) of primary energy and avoided 85 terragrams (Tg) carbon (C) equivalent. We project that EPA'S ENERGY STAR labeled products will save 13.4 EJ and avoid 212 Tg 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 (2007-2015) between 153 Tg C and 278 Tg C equivalent. decisions.
