EU Regulation 2023/1805 explained end-to-end — GHG intensity limits, penalty structure, pooling, compliance timeline 2025–2050, Well-to-Wake calculation, and the fuel pathways that matter for LNG operators.
FuelEU Maritime (Regulation EU 2023/1805) sets mandatory Well-to-Wake GHG intensity limits for fuel used on ships calling EU ports. Effective from 1 January 2025. Applies to all vessels ≥5,000 GT on voyages to, from, or between EU ports.
Unlike EU ETS which puts a price on carbon, FuelEU sets a HARD LIMIT on GHG intensity of the fuel mix. Ships must maintain average annual intensity below the year-specific limit or pay a penalty of €2,400 per tonne of VLSFO-equivalent fuel needed to reach compliance.
Well-to-Wake methodology means the entire fuel lifecycle counts — upstream extraction/production emissions + combustion emissions, with CH₄ (methane slip) and N₂O converted to CO₂-equivalent. This is stricter than IMO CII which uses Tank-to-Wake CO₂ only.
Baseline: 91.16 gCO₂e/MJ (2020 average of fossil marine fuels). Reductions apply to the annual company average across all EU-relevant voyages.
gCO₂-equivalent per MJ of fuel from Annex II of Regulation 2023/1805. LNG on 2-stroke engines is favourable; LNG on Otto-cycle (methane slip) is barely.
Penalty = €2,400 per tonne of VLSFO-equivalent fuel needed to reach compliance. Formula from Annex IV:
Penalty € = |Compliance Deficit in gCO₂e| × 2,400 / (LCV_VLSFO × Ref_intensity) = |Deficit| × 2,400 / (41,000 × 91.16)
Typical LNG voyage of 150 million MJ with 10 gCO₂e/MJ deficit → ~€960k penalty per voyage. Fleet-wide annual exposure for a 6-vessel LNG operator running conventional fuel: €50-100M.
VEMO FuelIQ calculates GHG intensity per voyage, projects annual deficit, and models pooling arbitrage across all your vessels.
Start Free Trial →Ships within a pool aggregate their compliance balances. A surplus ship (below the limit) transfers excess compliance to a deficit ship (above the limit). Pools must be registered with a verifier by 1 March of the reporting year.
Pooling reduces overall penalty exposure without altering the physical fuel used. Operators with a mixed LNG + conventional fleet can pool the LNG intensity-favourable vessels against the conventional deficit vessels.
Additional flexibility: borrowing — max 2% deficit borrowed from next reporting year (repay 1.1×) and banking — surplus carried forward.
