During the annual Greenbuild International Conference and Expo, the U.S. Green Building Council (USGBC) announced that more than 100 cities and communities have now achieved LEED certification. The City of Atlanta, this year’s Greenbuild host city, marked the 100th certification. USGBC launched LEED for Cities and Communities in 2016 as a globally consistent framework for measuring and tracking sustainability at the city and community scale. The rating system tracks progress across key performance indicators, including energy, waste, water, transportation, resilience, health and equity. Atlanta’s Mayor Keisha Lance Bottoms and USGBC’s President and CEO Mahesh Ramanujam announced the city’s certification and work during the conference’s Wednesday keynote.
