Beyond a Technocentric Transition: A Diverse Economies Perspective for Social Justice in Circular Economy Business Models

Business Strategy and the Environment, EarlyView.
ABSTRACT The circular economy, dominated by capitalocentric, technocentric, and eco‐modernist discourses, risks perpetuating systemic injustice because of its limited consideration of the social and of what is possible. In this article, we examine how social justice can be embedded into circular business models (CBMs)—key drivers of the circular ...
