Mid-year delivery can leave a carbon bill sitting between buyer and seller
A ship sale used to close around price, inspection, deposit, delivery and documents. In 2026, a serious closing file also needs an ETS allowance ledger, a FuelEU compliance balance, verifier timing, database handover and a clean settlement clause.
The mid-year sale problem is not that ETS and FuelEU are impossible to allocate. The problem is that they allocate differently. ETS behaves more like a period-by-period emissions bill. FuelEU behaves more like an annual ship compliance balance that can follow the vessel into the buyer’s hands.
That difference can move real money at closing. A seller may have created a FuelEU deficit before delivery. A buyer may become the December 31 responsible company. A charterer may owe reimbursement under separate charter-party terms. A verifier may not finalize the partial report until after the ship has changed hands. Without a settlement mechanism, the buyer can inherit uncertainty and the seller can face a delayed claim.
Split ETS by responsibility period. Settle FuelEU as a compliance balance at delivery, backed by verified or independently validated data, escrow and a post-verification true-up.
Carbon responsibility split
Buyer-seller checklist for the MoA
| Checklist item | Seller responsibility | Buyer protection | Closing document |
|---|---|---|---|
| ETS period split Emissions before and after delivery |
Calculate and support predelivery EU ETS emissions. | Do not accept predelivery allowance liability without a price credit. | Verified partial emissions report or strong estimate with true-up. |
| Allowance price Settlement value per tonne |
Agree a pricing date, EUA reference and currency treatment. | Avoid vague “market price” wording that invites dispute. | Price formula, exchange rate, calculation sheet. |
| FuelEU compliance balance Deficit or surplus through delivery |
Disclose validated balance and estimated balance to delivery. | Deduct or escrow for negative balance before taking the ship. | FuelEU balance statement, validator note, escrow instruction. |
| Borrowing restriction Future-period exposure |
Avoid borrowing against the delivery-year balance unless clearly agreed. | Block seller borrowing that improves today’s balance but hurts the buyer later. | Seller warranty and FuelEU borrowing covenant. |
| Pooling status Balance moved into or out of a pool |
Disclose any pooling decision, verifier and pool economics. | Confirm whether the buyer receives the benefit or inherits the risk. | Pool terms, verifier records, balance allocation memo. |
| Database handover THETIS MRV and FuelEU records |
Provide access-ready data and verifier communications. | Make database handover a closing item, not a post-closing favor. | User access plan, contact list, submission evidence. |
| Charterer recovery ETS and FuelEU pass-through |
Disclose receivables, claims, unpaid allowances and disputed invoices. | Separate recoverable carbon cost from owner-funded carbon cost. | Charter clauses, invoices, debit notes, receivable schedule. |
| Post-verification true-up Data finalized after delivery |
Cooperate after closing and deliver verified documents on time. | Hold escrow until the verified partial reports and compliance balance land. | Escrow release test, indemnity, cooperation covenant. |
Commercial read
ETS is the easier negotiation because the bill follows the responsibility period. FuelEU needs more care because the ship’s annual compliance balance can sit with the buyer at year-end even if much of the deficit was created before delivery.
Eight closing questions that prevent a fight later
Name the registered owner, ISM company, verifier, administering authority and account holder. Do not rely on shorthand like “the buyer will handle compliance.”
Split voyages, port calls, berth emissions, EU inbound and outbound legs, fuel records and noon reports around the exact delivery time.
Use the predelivery emissions record, the surrender factor, the allowance price formula and any charterer reimbursement to settle the seller period.
Separate verified prior-period balance, current-period validated balance, projected balance to delivery, banking, borrowing and pooling effects.
If predelivery activity created a FuelEU deficit, the buyer should receive a purchase-price deduction, escrow or liquidated amount.
A positive FuelEU balance may have value, but the buyer should confirm it is real, usable, bankable or poolable before paying for it.
Carbon reimbursement rights, unpaid invoices, charterer disputes and emissions clauses should be assigned or settled in the sale file.
Keep a holdback for unverified data, late partial reports, allowance price movement, FuelEU deficit risk and unresolved charterer recovery.

Closing file checklist
| File | Needed before delivery | Needed after delivery | Deal risk if missing |
|---|---|---|---|
| ETS emissions split | Predelivery tonnes, voyage list, port calls, berth emissions. | Verified partial report and submission evidence. | Buyer may face uncertainty over seller-period emissions. |
| FuelEU balance | Validated current balance and projection to delivery. | Partial FuelEU report and verification report. | Buyer may inherit a year-end deficit created before delivery. |
| Banking and borrowing | Seller statement that no hidden borrowing has shifted risk forward. | Database evidence and balance confirmation. | Future-period compliance can be distorted. |
| Pooling | Pool status, pool verifier, fees and allocation rights. | Proof of inclusion, withdrawal or balance treatment. | Surplus or deficit may not belong to the party assuming it does. |
| Charter recovery | ETS and FuelEU clauses, debit notes, unpaid amounts. | Assignment or settlement of receivables. | Carbon cost may be double counted or not recovered at all. |
| Escrow and true-up | Holdback amount, release trigger, price source and time limit. | Final reconciliation after verification. | Parties may fight after the ship and money have moved. |
Purchase price should be adjusted for the seller-period FuelEU balance and any unresolved ETS exposure, with escrow held until verified partial reports, FuelEU database records and allowance calculations are delivered.
Final settlement memo
In a mid-year ship sale, the cleanest approach is to split EU ETS allowances by the period of responsibility and settle FuelEU as a delivery-date compliance balance. The seller should carry predelivery ETS emissions, disclose and support FuelEU balances, avoid shifting risk through borrowing, and deliver verified partial reports. The buyer should protect the year-end FuelEU position with a deduction, escrow, indemnity and true-up. The deal can still close cleanly, but only if the carbon ledger is treated as part of the price.
