DOE announced a National Definition of a Zero Emissions Building to advance public and private sector efforts to decarbonize the buildings sector, which is responsible for more than one-third of total U.S. greenhouse gas emissions. The definition is intended to provide industry guidance to support new and existing commercial and residential buildings to move towards zero emissions across the entire sector and help the nation achieve President's ambitious climate goals, while cutting home and business energy costs. A standardized definition for zero emissions buildings will help advance next-generation clean energy solutions, drive innovation, and tackle the climate crisis, while supporting workforce development.
