Who Pays the EU ETS — Owner or Charterer? Charter Clauses, Explained

Legally, the EU ETS is simple: the shipping company — the DOC holder registered with an EU administering authority — must surrender allowances for the ship's in-scope emissions. Commercially, almost nobody intends the bill to stay there. Who actually pays depends entirely on the charter party, and in 2026, with 100% phase-in and three gases covered, the ETS clause is one of the most negotiated lines in a fixture. Here is how the allocation works in practice.

#Time charter: the cost follows control

The logic of the BIMCO Emission Trading Scheme Allowances Clause (and the house clauses derived from it) is that whoever directs the ship should pay for the emissions it produces. Under a time charter that is the charterer: they choose the voyages, the speed, the waiting, the cargo. The clause therefore obliges the charterer to provide allowances — or their monetary value — for emissions during the charter period, usually on a monthly cycle: owners notify emissions data, charterers transfer EUAs, and the parties reconcile against verified figures later.

Practical consequences for a chartering desk: every voyage order now has an allowance cost attached, redelivery timing affects who covers which month, and off-hire periods generate arguments about whose emissions they were. Desks that can produce a credible per-voyage ETS figure — route, scope, tonnes, EUAs — settle these conversations quickly; desks that cannot are negotiating blind.

#Voyage charter: priced into freight

Under a voyage charter the owner performs the voyage and keeps the compliance obligation, so the ETS cost behaves like bunkers: it goes into the freight calculation. That means the owner's estimate must get the scope right — 50% for an EU-to-non-EU voyage, 100% intra-EU, at-berth at 100% — and pick an EUA price assumption, before quoting. Some owners line-item an "ETS surcharge"; most simply build it into the rate. Either way, a mispriced carbon line comes straight out of the TCE.

#What each side should check before fixing

#If you are the charterer

• Which emissions are you liable for — the charter period's total, or only EU-scope emissions? The clause wording decides.
• Settlement in EUAs or cash? If cash, at what price reference and on what date?
• How are estimates trued up against verified MRV data, and who bears the gap?
• Does the clause address 2026 gas coverage (CH₄/N₂O) explicitly, or only CO₂? Older clauses drafted for 2024 sometimes do not.

#If you are the owner

• Does freight on EU-touching voyage charters include the allowance line at a stated EUA assumption?
• Are anti-evasion transhipment ports (e.g. East Port Said, Tanger Med) handled correctly in your scope logic?
• Is FuelEU Maritime allocated too? It is a separate bill with a separate (and less standardized) clause landscape — see our FuelEU penalty guide.
• Can you produce the per-voyage figure fast enough to use it in negotiation rather than discovering it at reconciliation?

#The estimation-methodology problem

Most ETS disputes are not about the principle — the clauses are clear enough — but about the number: whose distance table, whose consumption curve, whose scope interpretation. The clean solution both sides are converging on is to agree the calculation method in advance: a deterministic engine that takes the route and consumption, applies the regulation's scope and phase-in rules, and shows its assumptions. Then the negotiation is about the inputs, not the arithmetic.
