From Steel to Software: Shipping’s Green Turn

EU-backed virtual ship models turn climate pledges into practical, data-driven cuts in fuel use and emissions

9 Dec 2025

Europe’s shipping industry is turning to digital technology to meet stricter climate targets, as an EU-backed research project seeks to translate emissions goals into measurable operational gains.

Under the Horizon Europe programme, the DT4GS initiative is developing advanced “digital twins”, or virtual replicas of vessels that simulate performance in real time. The system allows shipowners and ports to test routes, speeds and fuel use before decisions are made at sea, aiming to reduce emissions without relying solely on new fuels or costly retrofits.

A digital twin mirrors a vessel’s physical condition by processing live operational data. It can model how a ship performs under different weather conditions, speeds and port schedules. Project leaders say this predictive capacity enables more precise fuel management and measurable carbon reductions, particularly through operational efficiencies targeted for 2030.

The approach comes as regulators increase pressure on the sector. Shipping remains a significant source of greenhouse gas emissions, and the EU Green Deal requires the industry to reduce its carbon footprint while maintaining trade flows.

Greater transparency over emissions is also reshaping competition among ports and operators. PortXchange’s EmissionInsider platform, used by hubs including Rotterdam, provides detailed data on transport-related emissions. The combination of vessel-level simulations and port-based monitoring signals a broader shift towards data-led compliance.

Members of the DT4GS consortium say digital twins are designed to convert climate commitments into operational results. At the same time, established marine technology groups such as Wärtsilä are expanding digital performance systems across global fleets, reflecting a wider industry move towards software-driven efficiency.

The transition, however, faces practical constraints. Questions over data governance, cybersecurity and system integration remain unresolved. Smaller operators may also struggle with upfront investment costs.

Even so, policymakers and industry groups see digital tools as central to meeting tightening environmental standards. As deployment moves beyond pilot projects, Europe’s maritime strategy is placing data at the core of its effort to align profitability with decarbonisation.
