EU ETS and FuelEU Maritime were written with large shipping companies in mind. The monitoring plans, carbon registries, allowance procurement cycles, and annual verification requirements all assume you have people whose full-time job is exactly this. Most small operators don’t. And the regulation offers no simpler version for those who don’t.
Since January 2024, every ship above 5,000 GT calling at EU or EEA ports has been required to purchase and surrender EU Emissions Trading System allowances — real money, real deadlines, real penalties for getting it wrong. The phase-in is steep: 40% coverage in 2024, 70% in 2025, 100% from 2026. For a single tanker or bulk carrier with significant EU trading exposure, that translates to an allowance bill of €100,000 to €500,000 per year — a cost that needs to be procured, tracked, and surrendered by 30 September each year without exception.
FuelEU Maritime, which entered into force in January 2025, adds a parallel framework on top. Where ETS charges you for what you emit, FuelEU sets targets for how clean your fuel needs to be — on a well-to-wake basis that captures the full lifecycle of every tonne of bunker consumed. Miss the GHG intensity target and the penalty is €2,400 per gigajoule of shortfall. The two regimes run independently of each other and require separate monitoring, separate reporting, and separate compliance strategies.
Since 2025 the net has widened further. General cargo ships and offshore vessels above 400 GT came into full MRV monitoring scope under the amended regulation — pulling thousands of smaller operators into a system they had little time to prepare for. For these vessels there are no ETS allowances to buy yet, but the monitoring obligation is real: approved monitoring plans, voyage-level fuel data collection, annual verified emission reports, and the Document of Compliance consequences that follow if any of it is missing.
The gap most small operators fall into is assumption
They assume their verifier handles ETS. They don’t — a verifier signs off the annual emission report. Everything else — the Union Registry account, the allowance procurement timing, the charter party cost recovery clauses, the FuelEU intensity tracking — is separate, and nobody is doing it unless someone is specifically engaged to do it.
They assume the compliance infrastructure transfers automatically when a vessel changes hands. It doesn’t. The monitoring plan needs to be updated in THETIS-MRV, fuel data collection needs to start from the first voyage under the new manager, and the ETS position for the year needs to be split and documented correctly between the outgoing and incoming company. Mid-year acquisitions are where the most common compliance gaps appear — and where port state control finds them.
They assume that because their vessels don’t currently trade EU waters, they have no exposure. They may not today. But for a bulk carrier, a single grain cargo from the Black Sea to Rotterdam fixes the vessel into full ETS scope from the moment it departs the load port. The liability builds from voyage one, with no grace period and no infrastructure in place to track or recover it.
What actually needs to be managed
The EU ETS compliance cycle has three hard deadlines every year. 31 March for the verified emission report. 30 June for the Document of Compliance to be on board. 30 September for allowance surrender. Miss the September deadline and the penalty is €100 per tonne of missing allowances — on top of still having to surrender them. These are not soft targets.
Between those deadlines, the active work is allowance position management. EUA prices have ranged between €50 and €75 over the past year. On a fleet with €1 million in annual surrender obligations, the difference between buying early at the bottom of that range and scrambling at the deadline at the top is a six-figure swing. That is a treasury management question, not a compliance checkbox.
FuelEU adds a data collection obligation that runs throughout the year — voyage-level GHG intensity calculations that feed into the year-end compliance position. Without visibility during the year, the first clear picture of where a vessel stands often arrives too late to do anything about it.
What we do
We work with small fleet managers and ship owners — typically one to ten vessels — to handle the full compliance cycle across both frameworks. One point of contact, end to end.
For vessels in ETS scope: allowance procurement strategy and timing, Union Registry account management, surrender execution, and charter party ETS cost recovery review so the cost lands where it should rather than sitting with the manager.
For vessels in MRV scope: monitoring plan drafting and registration, fuel data collection frameworks built around how the vessels actually operate, verifier identification and coordination, and annual report preparation and submission.
For FuelEU: GHG intensity baseline assessment, compliance gap analysis, monitoring methodology setup, and ongoing tracking through the year so the year-end position is known before it becomes a problem.
For companies taking on new vessels: handover compliance reviews, THETIS-MRV transfer management, and data continuity confirmation so nothing falls through the gap between the outgoing and incoming manager.
If you manage vessels above 400 GT that call EU or EEA ports — or that could call EU ports depending on how they are fixed commercially — the compliance infrastructure needs to be in place before the obligation arises, not after. The data being generated on every voyage right now is what the next reporting deadline depends on.
We are glad to review the compliance position of your fleet and tell you exactly where it stands.
