DOE published the "2023 Better Buildings Initiative Progress Report," which summarizes the achievements of DOE's Better Buildings public and private sector partners since the initiative's inception in 2011. The report shows that partnering entities, including more than 900 businesses, state and local governments, utilities, housing authorities, and other public and private organizations, to date have collectively saved $18.5 billion through efficiency improvements and cut harmful carbon dioxide emissions by nearly 190 million metric tons-- an amount roughly equivalent to combined annual emissions of 24 million homes. This report also includes the results of the Better Climate Challenge, an initiative that challenges major building portfolio owners and industrial partners to cut their greenhouse gas emissions by 50% within 10 years. In year one of the Challenge, partners have reported on nearly 1 billion square feet of buildings and 1,500 industrial plants. Through the Better Buildings Initiative, DOE aims to improve energy efficiency in the commercial, industrial, and residential sectors and accelerate cost-effective decarbonization solutions across the economy--supporting the Administration's efforts to lower energy costs for American families and businesses while addressing the climate crisis.
