The deliverable D1.2.1 Green Multimodal Transportation System Design Proposal presents the development of a low-emission, multimodal logistics framework within the WISTAR project (Waterways for Green Inland Sustainable Transport and Rural Businesses), funded by the Interreg North-West Europe program. The proposed system aims to connect rural producers with urban markets through optimized use of inland waterways, contributing to reduced carbon emissions, lower road congestion, and more cost-effective logistics particularly in the Normandy region in France, the Wallonia region in Belgium, and the Ruhr area in Germany. 

At the center of this system is an electric trimaran vessel designed by NEAC, tailored for shallow inland canals. Powered by renewable energy sources such as battery-electric propulsion, the vessel is engineered for minimal environmental impact, flexible modular cargo handling, and automated operation. Its design is particularly suited for last-mile delivery along the Caen Canal, linking the English Channel at Ouistreham to the city of Caen. 

To evaluate the system’s economic and environmental feasibility, CIRCOE developed a comprehensive simulation tool that compares the performance of electric barges with conventional diesel and electric trucks. The results demonstrate that while trucks provide operational flexibility, electric barges offer clear advantages in terms of cost per pallet and CO₂ emissions reduction on well-optimized routes. 

Coventuris contributed the conceptual design for scalable transshipment points—ranging from fully equipped multimodal hubs to low-cost rural quay integrated with renewable energy sources, digital control systems, and adaptable handling infrastructure. They also conducted a benchmark study on Transport Management Systems (TMS) to support efficient multimodal coordination. 

UDE introduced a system based on Reusable Plastic Crates (RPCs) to support circular, sustainable agri-food logistics. Additionally, UDE developed a delivery network model connecting the Lower Rhein region to urban centers in the Ruhr, utilizing inland vessels in combination with low-emission last-mile solutions such as cargo bikes and electric vans. 

Multitel supported the network planning through stakeholder consultations and spatial analysis conducted across France, Belgium, and Germany. Their work identified regional constraints, logistics opportunities, and infrastructural requirements essential for successful multimodal integration. 

Together, these contributions define a scalable and transferable model for sustainable freight transport in Europe. The WISTAR system aligns with the strategic goals of the Interreg North-West Europe program by advancing low-carbon mobility, supporting rural development, and promoting innovation in green logistics.
