What it is
FuelEU Maritime caps the GHG intensity (greenhouse-gas emissions per megajoule of energy used) of fuels burned on voyages touching EU/EEA ports. The target tightens every five years, pushing the fleet toward low- and zero-carbon fuels. The metric is Well-to-Wake (WtW): it counts emissions from extracting and producing the fuel (Well-to-Tank) plus emissions from burning it on board (Tank-to-Wake), expressed in gCO₂eq per MJ.Who it applies to
Ships 5,000 GT and above on voyages calling EU/EEA ports — Regulation (EU) 2023/1805. In force from 1 January 2025.The reduction trajectory
Baseline: 91.16 gCO₂eq/MJ (2020 fleet average).| Year | Target intensity (gCO₂eq/MJ) | Reduction vs. baseline |
|---|---|---|
| 2025 | 89.34 | −2% |
| 2030 | 85.69 | −6% |
| 2035 | 77.94 | −14.5% |
| 2040 | 62.90 | −31% |
| 2045 | 34.64 | −62% |
| 2050 | 18.23 | −80% |
Supported fuels
The platform handles 19 fuel types with EU Annex II default emission factors built in:Conventional

- Otto medium-speed: 3.1% (default)
- Otto slow-speed: 1.7%
- Diesel: 0.2%
- LBSI (lean-burn spark-ignition): 2.6%
Compliance and penalties
Compliance is computed at the fleet level (per operator):- Banking surplus from a year of over-compliance (up to 2 years forward)
- Borrowing up to 2% from next year’s target
- Pooling compliance with other ships under the same operator
What you see in the product
- Compliance banner — green or red, with the gap quantified in tonnes CO₂eq
- Daily intensity chart — fleet GHG intensity over the year against the target line
- Fuel breakdown table — consumption, energy (MJ), WtT, TtW, WtW, share %
- Per-vessel ranking — which vessels are pulling the fleet above target
- Reduction pathway — built-in reference table for 2025–2050
