Delegates at DNV’s second Energy Efficiency & Technologies Forum in Athens set out a clear practical agenda for maritime decarbonisation, arguing that the sector’s progress will hinge on verified operational performance, transparent economics and the ability to scale solutions from real-world experience. The forum convened shipowners, technology providers, academics and DNV experts to assess how ready current measures are for routine use at sea, and to identify the gaps that must be closed if ambitions are to be turned into measurable emissions reductions.
Participants placed operational evidence at the heart of the debate, stressing that demonstration alone is not enough unless it is accompanied by credible verification of results in service conditions. The emphasis was on data gathered from normal commercial operations rather than idealised trials, with the practical reproducibility of measures presented as the key test of readiness.
Verification and trust
Verification emerged from the discussions as the foundational requirement for any energy-efficiency or decarbonisation measure to be widely adopted, with delegates highlighting the need for consistent, transparent metrics and monitoring protocols. Without comparable, verifiable data, owners, financiers and charterers cannot judge performance, allocate risk or value investments in new technologies in a way that will support fleet-wide rollout.
Economics and scaling solutions
Speakers at the forum underlined that understanding the economics of measures in operational settings is the second critical pillar: the cost, payback profile and impact on vessel availability must all be demonstrably acceptable to the commercial decision makers who must sign contracts and write cheques. Scaling solutions, the discussions concluded, will therefore require not only technical validation but also clear evidence that implementation can be financed and operated without unacceptable commercial compromise.
The forum’s composition, a cross-section of shipowners, technology providers, academics and DNV experts, was presented as deliberately practical, chosen to assess “readiness” rather than to promote conceptual ideas. That framing directed attention to integration challenges, maintenance implications and the ways in which on-board teams will have to adapt procedures and training to deliver projected fuel and emissions savings in everyday trading patterns.
Delegates also explored the transactional consequences of operational evidence, noting that verified performance sits at the intersection of risk allocation, contracting and insurance. While technical merit is a necessary condition for adoption, the ability to translate performance data into contractual confidence and acceptable risk profiles was treated as equally decisive for accelerating uptake.
The forum in Athens, reported on 2 October 2026, therefore framed the immediate task for the maritime sector as operationalising decarbonisation: collecting the right data, evaluating economic outcomes in real service, and using those findings to guide scaled implementation. Attendees urged that future effort be concentrated on establishing the practical pathways by which technologies move from trial to common practice, so that claimed efficiencies become verifiable contributions to emissions reduction targets.
