The transition toward a circular economy (CE) requires collaborative governance arrangements that mobilize public authority, private capital, and technological capacity beyond the reach of any single actor. Public-private partnerships (PPPs) have long been used to finance and operate infrastructure, waste, and energy assets central to circular transitions, yet the intersection of CE and PPPs – Circular PPPs – remains conceptually dispersed and empirically thin.

However, current research at the intersection of PPPs, circularity, and decarbonization remains fragmented, scattered across sectors, and lacking conceptual synthesis. This study proposes a systematic review of the literature to map how PPPs support circular practices and whether these initiatives report climate-related benefits. Using Scopus as the prima...
