Urban logistics demand has soared due to post-pandemic e-commerce growth and rising fast-delivery expectations, pressuring cities to cut CO₂ and adopt greener practices. The Physical Internet (PI) envisions an open, interconnected network-warehouses, distribution centers, and retailers sharing resources via internet-style data handling and standardized modular containers-to streamline supply chains, lower costs, and reduce environmental impact. The HE DISCO project's Meta Model Suite orchestrates PI adoption by assessing urban digital maturity, using AI to recommend tailored innovations (locker alliances, optimal Urban Consolidation Centers), and offering strategic planning tools from HE URBANE. It also provides implementation of guide data frameworks, tools, and infrastructure-for seamless integration. Case studies in Ghent, Copenhagen, Thessaloniki, and Helsinki show marked congestion and emission reductions alongside better service delivery, illustrating PI's potential to transform urban logistics and boost sustainable, digitally competitive cities.
