Urban Ocean, a partnership of The Circulate Initiative, Resilient Cities Network and Ocean Conservancy, works with city leaders to bring new ideas, partners and resources together to solve interrelated problems around materials management, including addressing key priorities such as public health and economic development. As part of the Urban Ocean process, each Learning City conducts a Gap Assessment to map challenges, risk, and vulnerabilities within materials management systems and to develop an integrated picture of the materials and circular economy related challenges and opportunities faced by each city. The Circularity Assessment Protocol serves as a key tool in the Gap Assessment process and has been completed in each of the Cohort 1 cities for Urban Ocean.
