ClassNK has released ‘FAQs on the FuelEU Maritime (4th Edition)’, to serve as a helpful guide for stakeholders in the shipping sector when considering measures to comply with environmental regulations.
FuelEU Maritime, the EU regulation aimed at promoting the decarbonisation of fuels used on board ships, has entered into force and applies to all ships above 5,000gt calling at EU ports from January 1, 2025.
In the revised document, ClassNK has updated several sections reflecting the latest clarifications from EMSA’s webinar and the Guidance Document, including the following points:
- Conditions for cumulative penalty increases in cases of repeated penalties
- Priority order of fuels in GHG intensity calculation
ClassNK points out that by accounting fuels in the order of increasing GHG intensity, it is possible to maximise the benefit of using low-GHG-intensity fuels. Some points are yet to be clarified about the practical implementation of FuelEU Maritime, and thus the information provided is based on knowledge as of June 2025. Updated information will be provided accordingly once further details are clarified by the EU
