In 2007, ICLEI-Local Governments for Sustainability, the U.S. Green Building Council, and the Center for American Progress launched the concept for the STAR Community Rating System (STAR) at GREENBUILD in Chicago, IL. By 2008, they had established a formal partnership that included the National League of Cities to develop STAR. Their mission: to address the needs of U.S. cities, towns and counties seeking a common framework for sustainability. STAR is the nation’s first voluntary, self-reporting framework for evaluating, quantifying, and improving the livability and sustainability of U.S. communities. STAR uniquely combines: A framework for sustainability encompassing the social, economic and environmental dimensions of community; A rating system that drives continuous improvement and fosters competition; and an online system that gathers, organizes, analyzes, and presents information required to meet sustainability goals.
