About Us

TheCityFix is an online resource for learning about the latest in urban sustainability. Launched in 2007, the site connects a global network of writers, urban planners, designers, engineers, and citizens who work to make cities better places to live. The blog is produced by WRI Ross Center for Sustainable Cities, a program of the World Resources Institute that combines global research and on-the-ground experience to spur action to improve life for millions of people.

With experts based in Brazil, China, India, Mexico, and Turkey, WRI Sustainable Cities works together with local authorities, businesses and national governments on sustainable urban mobility, urban planning, building and energy efficiency, water risk, governance and resilience.

TheCityFix relies on this international community and other volunteer contributors to provide a global, multi-disciplinary perspective to its coverage of issues relating to urban sustainability.
