The circular economy can help us address many of the crucial challenges and problems that we and our planet face today, such as wastage in different forms, resource depletion and climate change. Cities have a very important role in the circular transition as cradles or ecosystems and catalysts for circular change. 

This guidance document outlines why cities should actively engage in and support others in the circular transition and how they can do that through 15 circular steps. The steps are divided into three phases: prepare and plan, facilitate and act, and invest and implement.
