FuelEU Maritime Regulation – How it works
FuelEU Maritime Regulation – How it works
Fuel EU Maritime Regulation (EU 2023/1805) (FuelEU Maritime), effective 1 January 2025, with first regulatory reporting and verification commencing in the first half of 2026, introduced stringent requirements to reduce greenhouse gas (GHG) emission intensity in the maritime sector.
One of the key challenges facing finance teams at shipowners and operators is translating the FuelEU Maritime’s complex compliance mechanisms into clear, supportable accounting outcomes. This means addressing a few critical questions: how should flexibility mechanisms, penalties, and compliance costs be recognised, measured, and disclosed in the financial statements?
FuelEU Maritime introduces a mechanism of linking emissions performance to profitability by imposing financial cost on shipowners that do not comply with defined fuel intensity thresholds. However, FuelEU Maritime’s structural complexity combined with the multiple compliance mechanisms and limited precedent for what would be an appropriate accounting treatment, has created uncertainty for operational and finance teams.
As the focus for organisations now shifts to ensuring that the financial implications of FuelEU are appropriately assessed, consistently applied, and audit ready. This is where organisations are increasingly seeking specialist support.
GHG Intensity requirements
The GHG intensity is calculated as total GHG emissions per total energy used. The regulation adopts a well‑to‑wake approach. Emissions are assessed across the full fuel lifecycle; from extraction or cultivation through production and transport to final combustion. This considerably broadens the emissions profile compared to traditional tank‑to‑wake measures.
The scope of the GHG intensity requirements is defined by voyage exposure to the EU/EEA. It covers 100% of energy used on intra EU/EEA voyages and while at berth in EU/EEA ports, and 50% of energy used on voyages entering or departing from the EU/EEA, including relevant outermost regions.
The baseline GHG intensity is set at 91.16 gCO₂e/MJ (based on 2020 levels). From this starting point, the regulation imposes a progressively tightening reduction pathway, beginning at 2% in 2025, increasing to 6% in 2030, and scaling up towards an 80% reduction by 2050. This trajectory creates a steadily increasing compliance gap for vessels relying on conventional fuels, reinforcing the need for new operational strategies.
FuelEU Maritime Compliance and Flexibility Mechanisms
Under the regulation, the responsibility for compliance lies with the shipowner, or with any other organisation or person such as the manager or bareboat charterer that has assumed responsibility for operating the ship from the shipowner and has agreed to take on all duties and obligations set out in the International Safety Management (ISM) Code.
Non-compliance with the GHG intensity targets results in financial penalties calculated per ton (or unit of energy) of excess fuel-equivalent emissions, with escalating penalties for repeated breaches. FuelEU Maritime offers several alternative compliance mechanisms for ships that do not meet the required GHG intensity. A central element for these mechanisms is the compliance balance which must be calculated for each ship as part of the annual regulatory compliance reporting process.
A ship with an actual GHG intensity below the required level will have a positive compliance balance, and a ship with an actual GHG intensity above the required level will have a negative compliance balance.
The regulation provides the following flexibility mechanisms to enable compliance:
- Banking: Positive compliance balance can be banked for future periods (no expiry). Banked surplus cannot be transferred to other ships (even for the same ship owner).
- Borrowing: Negative compliance balance can be borrowed from next year, with +10% penalty applied, but no borrowing is allowed for two consecutive periods. This means that if the company still has a negative balance in the subsequent year, it is not permitted to borrow again.
- Pooling: Ships (even from different owners or operators) can pool compliance balances and re-allocate compliance balance between the individual ships, if:
- Total pool balance is positive;
- Ships that had a compliance deficit do not end up with an even higher compliance deficit after the reallocation of the compliance balance;
- Ships which had a compliance surplus do not have a compliance deficit after the reallocation of the compliance balance.
A ship can only join one pool for each annual reporting period.
Penalties
Ships with negative compliance balance after any banking, borrowing, or pooling will have to pay a penalty corresponding to its compliance deficit. The penalty is set to about €58.54 per GJ of non-compliant balance.
Monitoring, Reporting & Verification (MRV)
The first regulatory reporting period of Fuel EU is 1 January to 31 December 2025. Following the end of this reporting period, the first verification cycle commenced in January 2026 for all ships within scope of the Regulation. All in-scope ships are subject to the same verification framework and timetable. The verification process follows a set of prescribed milestones, which are outlined below:
