Shaping the future of decarbonisation in shipping
As the maritime industry enters a new year, technology group Wärtsilä has identified four important trends that will affect global shipping in 2026.
From the rise of digitalisation and big data to the growing importance of flexible decarbonisation strategies, these trends are set to redefine competitiveness, efficiency and sustainability for vessel owners and operators worldwide.
Lifecycle optimisation
With rapid technological advances and evolving regulations, vessel owners are shifting from short-term fixes to holistic, long-term strategies. Lifecycle optimisation considers environmental impact, operational efficiency and economic viability from vessel design through to end of life, supporting smarter investment decisions and asset value preservation. Collaboration and transparency between owners, operators and OEMs are key to maximising benefits and navigating future uncertainties.
Flexible decarbonisation strategies
Decarbonisation approaches must be tailored to each vessel’s operational profile, available fuels and business priorities. A flexible strategy – encompassing planning, integration and continuous monitoring – ensures vessels remain competitive and compliant as technology and regulations evolve. Investments in fuel-flexible engines, hybrid propulsion and methane slip mitigation are among the solutions enabling owners to future-proof their fleets.
Retrofit option
“Retrofitting is rapidly becoming the most practical decarbonisation pathway for much of the existing fleet,” says Peter Hanstén, Director of Business Development for Project Services at Wärtsilä Marine. “Owners are under pressure to cut emissions, but few can afford to commit to a single fuel or technology today. That is why flexibility is so critical. Upgradable engines, hybrid power solutions, energy-saving devices and digital optimisation allow vessels to reduce emissions now, while keeping future sustainable fuel options open. The most successful retrofit strategies are not about chasing one solution, but about building step-by-step resilience into assets that still have decades of service ahead.”
Digitalisation, big data and analytics
The increasing complexity of vessels – featuring hybrid setups, advanced power management and alternative fuel systems – demands robust digital integration. Harnessing onboard data through advanced analytics enables real-time operational recommendations, driving significant reductions in fuel consumption, emissions and operational costs. While some industry leaders are already leveraging these capabilities, widespread adoption is still hindered by challenges such as data governance and integration. But the path forward is clear.

Less predictable regulations
Despite the recent delay in the IMO’s Net-Zero Framework, the regulatory landscape continues to evolve, with regional initiatives like the EU Emissions Trading System and FuelEU Maritime impacting a significant portion of global shipping. As businesses prepare for stricter emissions requirements, robust compliance and reporting protocols are becoming essential.
Looking ahead
“As we look ahead to 2026, collaboration will play a vital part in driving the sustainable transformation of shipping and shaping a cleaner and smarter future for the maritime industry,” says Roger Holm, President, Wärtsilä Marine. “Wärtsilä’s leadership in fuel flexibility, integration and cross-industry partnerships reflects the growing need for OEMs, operators, ports, fuel providers and regulators to work together. We stand shoulder-to-shoulder with our customers, bringing innovative solutions, expert guidance and a clear focus on enhancing efficiency and creating long-term value.
“Legislation is critical to accelerating investment in alternative fuels, but it is no silver bullet,” he continues. “Decarbonisation is a team effort. The maritime ecosystem is full of remarkable ingenuity and world-class technical excellence that we can use to drive decarbonisation and digitalisation hand in hand. We already have the tools in the toolbox to build a cleaner, smarter future for global shipping.”
