This multi-authored book aims to illustrate the social, economic, and ecological factors that should determine and be determined by design in the implementation of a sustainable circular economy and society. We take design to refer to a continuum of perspectives and applications from industrial design to policy design, and this broad perspective invites theoretical and methodological contributions from a range of fields. In addition to bringing scholarly diversity to circularity, we expand and challenge the mainstream circular economy narrative of material efficiencies and green growth to include the demands of inclusive growth and ecological boundaries consistent with sustainable development. Readers from within and beyond design, conscious of the limitations of circular green growth will find new inspiration in this book regarding the nature of a sustainable circular economy and society and the broad design agenda that must be implemented to enable a just and informed circular transition.
