This article examines open innovation approaches promoting the development of stakeholder-driven circular economy models. 

It describes key elements of open innovation and circular value cocreation,  utilises the findings from a systematic review to identify opportunities and challenges related to the open circular innovation paradigm, and presents theoretical implications and an action plan highlighting the importance of engaging in collaborative behaviour with stakeholders.

It emphasises a cocreation culture that encourages the sharing of resources, competencies and capabilities, while safeguarding organisations' IP. It finds that there is scope for practitioners to develop circular economy ecosystems that increase practitioners' bottom lines, while reducing their environmental impact.

Cities have a critical role to play in the transition from a linear to a circular economy. They are centres of consumption and production, and they host the systems and policies that enable and govern urban life. 

This guidance document aims to help cities identify actions and solutions that can accelerate their circular transition. The document covers eight key sectors with high circular potential: Built environment, Consumer goods, Food, Manufacturing, Mobility and logistics, Tourism and leisure, Waste and material management and Water and wastewater management. 

The circular approaches that can be adopted in each sector are introduced first, and this is followed by examples of potential circular actions and solutions.

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.
