Not sure which solution fits your vessel?
We help you compare technologies based on your vessel, operating profile, fuel consumption and decarbonization goals.
* Performance and savings depend on vessel type, operating profile, route, system configuration and other project-specific conditions. Figures shown are indicative and based on technology-provider information and/or project results.
Decarbonization regulations → practical solutions
Different regulations require different approaches. FuelEU Maritime, EU ETS and CII/EEXI increasingly connect vessel efficiency, fuel choice and emissions performance with operational and financial consequences.
FuelEU Maritime
Reduce GHG intensity through fuel efficiency, electrification and alternative fuels.
EU ETS
Lower fuel consumption and reportable CO₂ emissions.
CII / EEXI
Improve vessel efficiency with wind assist, electrification and energy-saving technologies.
2030–2050 transition
Prepare vessels for alternative fuels, hydrogen and deeper emission reductions.
