This Recommendation establishes a circular city implementation framework that is designed to improve circularity in cities and support stakeholders in implementing circular actions. The framework consists of a four-step methodology that provides a consistent and scientific method to assess, prioritize, apply and catalyse different circular actions in the city setting. This Recommendation introduces the concept of city assets and products (i.e., city infrastructure, resources, services etc.), circular city actions (which can be applied to assets and products), circular city output (i.e., the results of applying circular actions to city assets and products) and circular city enablers (i.e., complementary actions that support the implementation of circular city actions). The Recommendation helps cities to identify a clear course of action to improve sustainability and achieve Sustainable Development Goal (SDG) 11, Sustainable cities and communities, and the related targets.

This Recommendation has been developed in response to the growing sustainability challenges that cities are facing and the emergence of the circular economy concept and its applicability and extension in the city setting. This Recommendation was developed based on the United for Smart Sustainable Cities (U4SSC) initiative deliverable of the same name [b-U4SSC GCC].
