Decisions made today regarding land use, transportation, water, economic development, and social services will have enormous long-term impacts on the future sustainability of our megapolitan region. Recognizing this, Arizona State University’s Global Institute of Sustainability and Innovation created the Sustainable Cities Network, which works with local communities to explore sustainable approaches and address challenges. This network was founded in 2008 to support communities in sharing knowledge and coordinating efforts to understand and solve sustainability problems. It is designed to foster partnerships, identify best practices, provide training and information, and connect ASU’s research to front-line challenges facing local communities. Network members come from Arizona cities, towns, counties, and Native American communities, and cover a broad range of professional disciplines. Together, these members work to create a more sustainable region and state. In 2012, the network was awarded the Pacific Southwest Region’s 2012 Green Government Award by the U.S. EPA for its efforts. For more information, visit sustainablecities.asu.edu.
