THE recent failure to secure agreement on the IMO’s Net-Zero Framework has created renewed uncertainty for shipowners at a moment when long-term clarity is needed. A global path was expected to guide investment decisions and support consistent planning. Without it, there is a heightened risk that shipowners may face rising costs as they attempt to comply with a complicated and still developing mix of national and regional measures.

In the absence of a unified approach, regions are pressing ahead with their own initiatives, each designed to address emissions in ways that reflect local priorities. Europe is already far advanced with EU ETS and FuelEU Maritime, while regulatory ideas are gaining momentum in Asia and Africa.

Although these initiatives share the intention of reducing emissions, they differ in scope, data requirements and cost structures. Shipowners trading across multiple areas must therefore prepare for obligations that may vary depending on where their vessels operate.

Understanding the distinction between greenhouse gas intensity rules and energy efficiency requirements has become increasingly important. The introduction of European measures highlighted how easily unplanned exposure can arise. Operators that call at European ports for only part of the year found that even short visits carried consequences they had not anticipated. With other regions exploring their own approaches, the challenge of forecasting how operational patterns influence compliance costs is becoming a central concern for owners.

Alongside regulatory questions, owners must assess which technological paths offer practical progress. LNG continues to be the preferred option for many newbuildings due to its maturity and established infrastructure. Methanol is attracting attention for retrofits, offering a more straightforward transition from traditional liquid fuels. Ammonia is also being explored, particularly for merchant vessels, although handling and safety considerations remain significant factors.

Energy efficiency continues to provide the most immediate opportunities for meaningful emissions reduction. Improvements in hydrodynamic design, propulsion systems and energy utilisation are already delivering measurable gains. Waste heat recovery, once mainly associated with newbuildings, is now being applied more widely to existing vessels. Battery systems and shore power connections are also becoming more common, providing options for reducing consumption without depending on future fuel availability.

A stronger partnership offering shipowners more than the sum of its parts

The passenger and cruise sectors have been early adopters of many energy efficiency and retrofit solutions. These ships present unique engineering challenges because of their dense machinery layouts and significant hotel loads. Foreship’s extensive experience in this segment, developed through thousands of projects, has produced practical insights that are increasingly valuable across the wider maritime industry. Lessons learnt from integrating new systems into constrained spaces and maintaining operational continuity translate directly to other vessel types.

RINA’s acquisition of Foreship has brought together deep expertise in the passenger and cruise sectors with comprehensive capabilities. This creates a more complete and accessible resource for shipowners facing tightening expectations and evolving compliance requirements. As regulation continues to evolve, the combined organisation offers shipowners practical engineering insight helping them assess their options with greater confidence at a time when environmental rules are shifting and compliance pathways are still taking shape.

Conclusion

Shipping’s decarbonisation journey will benefit greatly from global alignment, yet the path to that alignment may take time. Until then, owners must navigate a landscape that is still forming, shaped by regional initiatives and advancing technologies. Realistic, integrated guidance will be essential. By drawing on the combined strengths of RINA and Foreship, shipowners gain a more reliable foundation to manage uncertainty and prepare their fleets for a lower-carbon future.
