This report shifts the focus from corridor-based thinking to scalable networks built on reusable transport legs.

The key insight of this report is that scalable multimodal freight systems are built around qualified transport legs – recurring service connections between logistics nodes such as ferry routes, rail segments, or road links. Nordic sustainable transport networks emerge when such qualified legs are reused across multiple freight flows.

Scaling requires shared performance governance, based on transparentand comparable KPIs across cost, delivery time, and emissions.

The report introduces a scenario-based method for comparing alternative network configurations. Digital collaboration strengthens coordination across multimodal logistics systems and supports credible emissions accounting (Maritime and Port Authority of Singapore, 2025).The Virtual Watch Tower is highlighted as an example of public-good digital infrastructure supporting end-to-end collaborative decision making, disruption management, and leg-level emissions transparency.

Finally, the report emphasizes that sustainable transport networks cannot scale within the transport system alone. Decarbonization requires coordinated transformation across interconnected value chains, including sustainable fuel supply, logistics operations, and carrier asset transitions (Petersen and Renken, 2023). Parallel Nordic initiatives such as the Nordic Roadmap for the Introduction of Sustainable Zero-Carbon Fuels in Shipping focus on green shipping corridors and the associated maritime energy ecosystem across the corridor value chain. The present report complements this work by introducing a shipper-driven logistics perspective focused on how transport buyers adopt and scale sustainable freight solutions across multimodal logistics networks.

The Nordic opportunity therefore lies in prioritizing high-impact transport legs, equipping shared nodes with interoperable digital collaboration mechanisms, applying shared KPI frameworks, and aligning transport networks with sustainable energy ecosystems. In this way, existing green corridor initiatives can be extended into scalable multimodal Nordic freight systems.
