Summary

Recommendation ITU-T L.1620, Guide to circular cities, contains 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 method for assessing, prioritising and catalysing different circular actions. The Recommendation is 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. Supplement 50 to ITU-T L-series Recommendations aims to further support the circular city implementation framework by providing 17 case studies on cities implementing circularity in urban operations.
