The Blue City Network is a certification system that recognizes cities, towns, and counties that demonstrate their communities’ commitment to healthy waterways and oceans. Participants gain access to proven resources and blueprints provided by our network of nonprofit partners, certified cities, and governmental agencies. Upon certification, participants become part of the Blue City Network, a coalition of communities from around the world that collaborate on programs and policies that protect the marine environment. Blue City certification provides cities with a way to publicly display their efforts and be seen as responsible environmental stewards.

Established by Project-O, a 501c3 ocean conservation organization, the Blue City Certification program provides a data-driven approach to assessing communities’ efforts toward protecting the ocean. The intent of this program is to establish a network of cities and counties that are willing to implement, collaborate, and share information on jurisdictional sustainability programs across four Solution Areas: Waste Minimization, Climate Protection and Resilience, Healthy Ecosystems, and Water Quality and Efficiency.
