About CIN
The Circular Impact Network was founded in 2020 by a group of sustainability practitioners who believed the circular economy transition needed a different kind of infrastructure — one built on trust, cooperation, and shared learning.
Today, CIN runs programs across 18 cities, convenes hundreds of changemakers, and builds open-source tools that help communities and businesses shift toward more regenerative models.
