Digital‑Twin Corridors Take Shape in the Baltic

The Council of the Baltic Sea States convened member nations to kick‑off a Green Shipping Corridor digital‑twin—a virtual copy of the sea basin layering AIS, met‑ocean and port data. The twin will run 'what‑if' fuel‑switch scenarios (e‑methanol, green ammonia) and publish optimal schedules for shore‑power windows. Pilot simulations suggest a 35 % cut in waiting‑at‑anchor time for ro‑ro services between Tallinn and Stockholm, equating to ~6 kt CO₂ per corridor per year.
