Logistics parks are considered as megaporojects due to the scale, multi-stakeholder complexity they reach, as well as for to the long-term public value they are able to create. This chapter investigates how Public–Private Partnerships (PPPs) in the logistics sector can advance social sustainability within large-scale logistics parks. The research question examines under which governance conditions logistics PPPs—typically associated with efficiency-driven infrastructure—can also function as platforms for social innovation and territorial well-being. The study’s contribution lies in its in-depth analysis of the Prologis Park Piacenza case, showing how integrated ESG strategies, collaborative governance, and impact-measurement tools such as SROI reshape a logistics hub into a hybrid infrastructure generating economic, environmental, and social value. By conceptualizing logistics parks as meso-level megaprojects, the chapter extends existing PPP literature toward a people-centred and territorially embedded perspective. The implications suggest that well-structured PPPs can operate as drivers of urban regeneration, human-capital development, and community cohesion, provided that negotiation processes, risk-sharing mechanisms, and accountability structures are robust. The Piacenza model thus offers a replicable framework for logistics regions seeking to balance competitiveness with long-term territorial sustainability.
