CNT is a nonprofit organization, headquartered in Chicago, that helps cities use resources more efficiently and equitably. We research, invent, and test urban strategies that integrate economic development, environmental sustainability, and technology, with a focus on low-income communities and communities of color. For four decades, we have been known for our advanced analytics, thorough community engagement, and innovative ideas to help communities solve their present and future challenges. Our work is not just about making cities more efficient; it is about finding solutions that benefit all people. We have collaborated on urban sustainability work all over the country, and our current priorities include water infrastructure, equitable transportation-oriented development (eTOD), and climate resilience. Our projects, such as the Great Lakes Water Infrastructure Project, show that urban efficiency, poverty reduction, and sustainability can go hand in hand.
