FuelEU Maritime Balance Calculator

Estimate your vessel’s well-to-wake (WtW) GHG intensity, FuelEU compliance balance and potential penalty exposure for any reporting year from 2025 onwards. Built by Varuna Sentinels BV.

First compliance balance deadline: 30 April 2026

FuelEU Maritime applies to ships above 5,000 GT calling at EU/EEA ports.
Enter your fuel mix for energy used on EU voyages, EU port stays, and 50% of voyages between EU and non-EU ports. Tonnes per year.

Indicative estimate only — not legal, regulatory, financial, investment or compliance advice. Penalty figures are illustrative and do not constitute a binding assessment of your FuelEU liability. Final compliance balance and penalty depend on FuelEU verifier-approved Well-to-Wake values (per fuel batch), monitoring plan, RFNBO multipliers, pooling/banking elections and current Commission Implementing Regulations. Default Well-to-Wake intensity values used here are industry-indicative and may differ materially from verifier-approved actuals. Varuna Sentinels BV accepts no liability for commercial, operational or compliance decisions made solely on this output. For binding figures, engage your FuelEU verifier and Varuna Sentinels for compliance support.

How the FuelEU Maritime Balance Calculator works

The FuelEU Maritime Regulation (EU) 2023/1805 entered into force on 1 January 2025 and introduces a goal-based, well-to-wake (WtW) greenhouse gas (GHG) intensity standard for energy used on board ships of 5,000 GT and above calling at EU/EEA ports. The first compliance balance deadline is 30 April 2026 for the 2025 reporting year.

The standard is set against a 2020 reference value of 91.16 g CO₂eq/MJ, with progressive reductions:

Compliance is measured by computing your fleet’s actual WtW GHG intensity (weighted by energy consumed) and comparing it to the target. A surplus is bankable or poolable; a deficit triggers a penalty of EUR 2,400 per tonne of VLSFO-equivalent, calculated from the magnitude of the deficit divided by the energy density of VLSFO at the target intensity.
