FuelEU Maritime Regulation
Status: In-force — GHG intensity limits are now in force with escalating reduction targets through 2050.
What Is It?
The FuelEU Maritime Regulation (EU 2023/1805) establishes a well-to-wake greenhouse gas intensity standard for the energy used by ships calling at EU/EEA ports. Unlike the EU ETS which prices carbon emissions, FuelEU Maritime directly mandates a reduction in the greenhouse gas intensity of marine fuels, measured in grams of CO2 equivalent per megajoule of energy (gCO2eq/MJ), on a progressively tightening trajectory from 2025 through 2050.
The regulation requires shipping companies to reduce the annual average GHG intensity of energy used onboard their vessels by 2% from the 2020 reference value starting in 2025, escalating to 6% by 2030, 14.5% by 2035, 31% by 2040, 62% by 2045, and 80% by 2050. This trajectory is designed to drive the adoption of renewable and low-carbon fuels — including advanced biofuels, e-methanol, e-ammonia, renewable hydrogen, and other RFNBOs — as conventional marine fuels cannot achieve the required reductions on their own.
FuelEU Maritime also introduces a sub-quota for Renewable Fuels of Non-Biological Origin (RFNBOs) from 2034, an onshore power supply (OPS) mandate for container ships and passenger vessels at major EU ports from 2030, and a compliance pooling mechanism that allows shipping companies to aggregate the compliance balance across multiple vessels. Companies that exceed the GHG intensity limit face a financial penalty calculated per megajoule of non-compliant energy, with the option to borrow from the next compliance period (at a 10% premium) for the first time only.
Who It Affects
FuelEU Maritime applies to all vessels of 5,000 gross tonnage and above regardless of flag, in respect of the energy used during voyages between EU/EEA ports (100% of energy), voyages from an EU/EEA port to a non-EU/EEA port (50% of energy), and voyages from a non-EU/EEA port to an EU/EEA port (50% of energy), as well as all energy used at berth in EU/EEA ports. The regulation covers the same vessel categories as the EU MRV regulation, including container ships, bulk carriers, tankers, gas carriers, passenger ships, and ro-ro cargo vessels. The compliance obligation rests with the shipping company as the ISM DOC holder.
Key Dates
FuelEU Maritime enters into force — 2% GHG intensity reduction target begins
Submission of first FuelEU Maritime monitoring plans to verifiers
GHG intensity reduction target increases to 6%; OPS mandate begins for container ships and passenger vessels at TEN-T core ports
RFNBO sub-quota of 2% introduced for fuel energy used onboard
GHG intensity reduction target increases to 14.5%
GHG intensity reduction target increases to 31%; RFNBO sub-quota rises
Requirements
- Calculate the well-to-wake GHG intensity of all energy used onboard for voyages involving EU/EEA ports
- Achieve the required annual GHG intensity reduction against the 2020 reference value of approximately 91.16 gCO2eq/MJ
- Apply default emission factors from Annex II for each fuel pathway, or certified actual values for sustainable fuel batches with chain-of-custody documentation
- Submit annual FuelEU Maritime compliance reports to the administering authority, verified by an accredited verifier
- Comply with the RFNBO sub-quota requirement from 2034 onward
- Ensure container ships and passenger vessels connect to onshore power supply at applicable EU ports from 2030 (with defined exemptions)
- Manage compliance balance through pooling, borrowing, or penalty payment for any GHG intensity exceedance
- Maintain records of fuel types, quantities, sustainability certifications, and energy consumption for each voyage
Penalties & Non-Compliance
Shipping companies that fail to meet the annual GHG intensity target face a FuelEU Maritime penalty calculated as the compliance deficit in megajoules multiplied by a penalty factor (EUR 2,400 per tonne of VLSFO equivalent). For a large vessel with a 5% intensity gap, annual penalties could reach EUR 1-3 million. Companies may borrow from the next compliance period once, but at a 10% premium — the borrowed deficit must be repaid in addition to meeting the next period's target. Failure to comply with the OPS mandate carries separate penalties. Persistent non-compliance over two or more consecutive periods triggers the same port entry ban mechanism as the EU ETS, effectively preventing the vessel from trading in EU/EEA waters until obligations are resolved.
