Circular economy has received significant attention worldwide for its potential to reconcile ecological limits and economic development. Europe, in particular, has made it a policy focus for achieving its climate ambitions. However, to date, the circular economy remains a loosely defined concept with competing discourses of technocentrism and holistic societal transformation. As the former prevails, its neglect of the social dimension raises concerns about the circular economy's social sustainability and feasibility. Therefore, this study explores how the relationship between the circular economy and the social dimension is perceived by experts directly engaged in the current circular transition process. By uncovering their experiences and perceptions, this study aims to offer empirical insights for the future development of the circular economy. Through qualitatively exploring the views of 14 experts across 11 European cities with a clear circular vision, this study found that although the social dimension is not a primary focus or fundamentally connected with the circular economy, it plays a fundamental role in the transition process and is simultaneously an impacted area. However, there is a significant gap between the ideal social environment required for circular transition and what the current transition can facilitate. As such, the future of the circular economy may be precarious unless it shifts from a technocentric tendency to more holistic, transformational approaches.
