EU ETS surrender mechanics for shipping
The EU ETS cycle for ships: 31 March verified report, 30 September EUA surrender, EUR 100 indexed penalty, and Article 16 enforcement.
Surrender is the act that closes the loop in a cap-and-trade system. Every shipping company subject to Directive (EU) 2023/959 must deliver, by 30 September of year y+1, EU Allowances (EUAs) equal to its verified CO2-equivalent emissions liability for calendar year y, scaled by the applicable phase-in factor. The annual cycle starts on 1 January when emissions begin to accrue under Regulation (EU) 2015/757 . It pivots on 31 March y+1 when the verifier-attested emissions report must be submitted into THETIS-MRV. The cycle closes with the 30 September y+1 surrender executed in the Union Registry. Failure to surrender triggers Article 16(3): a EUR 100 per tonne excess-emissions penalty indexed for EU inflation since 2013, plus the continuing obligation to still deliver the missing allowances, plus eventual port-state denial under Article 16(11a) if non-compliance persists across two reporting periods. The two cards below compute ship-level surrender quantities and the fleet surrender schedule.

Surrender as the consequence step in cap-and-trade
A cap-and-trade market has three operational moments. Allocation is when the regulator creates allowances and distributes them, by free issuance or auction. Trading is when covered entities and intermediaries reallocate allowances to whoever values them most. Surrender is when each covered entity hands back to the regulator allowances equal to its verified emissions, and the regulator cancels them. Without surrender, the allowances created at allocation would not constrain behavior, and the cap would be a paper construct.
The EU Emissions Trading System established by Directive 2003/87/EC and extended to maritime by Directive (EU) 2023/959 is the largest carbon market in the world by traded value. Shipping entered the cap on 1 January 2024 with zero free allocation. Every EUA a shipping company surrenders must be bought on the EEX primary auction, on secondary spot, or via futures on ICE Endex or EEX. Surrender translates the abstract cap into a live cash obligation on every voyage calling an EU or EEA port.
Three features separate maritime surrender from the rest of the ETS. The verified emissions figure is a per-company aggregate built from per-voyage and per-vessel data under Regulation (EU) 2015/757 , as amended by Regulation (EU) 2023/957 to add CH4 and N2O from 2026. The responsible legal entity is the shipping company as defined in Article 3(w), not necessarily the registered vessel owner. The directive also adds a port-state-control escalation under Article 16(11a) that can deny a non-compliant company’s ships entry to EU ports, an enforcement lever no other ETS sector faces.
The “shipping company” definition under Article 3(w)
Article 3(w) of the directive defines the shipping company as the shipowner or any other organisation or person, such as the manager or the bareboat charterer, that has assumed responsibility for the vessel’s operation from the owner and that, on assuming such responsibility, agreed to take over all duties imposed by the International Safety Management (ISM) Code. The definition aligns with the entity holding the Document of Compliance (DoC) under the ISM Code and appearing on the Continuous Synopsis Record (CSR) under SOLAS regulation XI-1/5.
The attribution resolves in three layers. If the registered owner operates the vessel itself, the owner is the shipping company. If the owner transferred operational ISM responsibility to a third-party manager, the manager is the shipping company; this covers the vast majority of tankers, bulkers, and container ships managed by firms such as V.Group, Anglo-Eastern, Bernhard Schulte, Synergy, and OSM Thome. If the vessel is under bareboat charter and the bareboat charterer holds the DoC, the bareboat charterer is the shipping company.
Time charter and voyage charter do not transfer ISM responsibility. A time charterer pays for bunkers and directs commercial employment but is not the Article 3(w) shipping company and does not surrender EUAs. That asymmetry sits at the heart of the BIMCO ETS Allowances Clause discussed in a later section.
The Commission and EMSA maintain a registry of attributed shipping companies in THETIS-MRV. Each company is mapped to an administering authority under Article 3gf(1): the Member State where the company is registered; otherwise the Member State with the greatest estimated number of port calls from its in-scope voyages in the preceding four monitoring years; and for a company with no in-scope voyage in those four years, the Member State where a ship of the company started or ended its first in-scope voyage.
Annual compliance-cycle timeline
The maritime ETS surrender cycle spans two calendar years. Year y is the emissions year, when CO2 (and from 2026 also CH4 and N2O) accrues on covered voyages. Year y+1 is the reporting and surrender year, when the verifier checks the data, the company files the verified report, and the company executes the registry transactions.
| Deadline | Action | Legal basis |
|---|---|---|
| 1 January, year y | Emissions begin to accrue; approved monitoring plan in force | Reg. (EU) 2015/757, Art. 6 |
| 31 March, year y+1 | Verifier-attested annual emissions report submitted to THETIS-MRV | Reg. (EU) 2015/757, Art. 11 |
| 30 June, year y+1 | Commission makes reported CO2 emissions information publicly available | Reg. (EU) 2015/757, Art. 21(1) |
| 30 September, year y+1 | Statutory surrender deadline: EUAs transferred to EU Surrender Account | Dir. 2003/87/EC, Art. 12(3) |
The 30 September surrender deadline in Article 12(3) was set by Directive (EU) 2023/959 when shipping joined the ETS. The same amendment moved the deadline from 30 April to 30 September for installations and aircraft operators as well (recital 66). Two operational points shape sequencing. The 31 March report is per company but is assembled from per-ship voyage records streamed through the company’s MRV data system throughout year y. The verifier’s reasonable-assurance fieldwork typically begins in January y+1 on a sample of voyages.
Verifier-attested emissions report: 31 March deadline
The MRV report under Article 11 of Regulation 2015/757 carries, for each ship operated in year y, the parameters required to compute the EUA liability: total fuel consumption by type and grade, CO2 emissions by voyage, distance travelled, time at sea, transport work in tonne-miles or passenger-miles, average energy efficiency, and the breakdown of emissions across four scope categories. From 2026 the report also carries CH4 and N2O emissions per Regulation (EU) 2023/957 . Monitoring plan changes during year y appear in an addendum.
The accredited verifier issues a reasonable assurance opinion. Reasonable assurance is the highest assurance level available under IFAC standards and is materially equivalent to a financial audit opinion: the verifier states the report is free from material misstatement and that the underlying monitoring complied with the approved monitoring plan. The verifier checks data lineage from bunker delivery notes, noon reports, engine and tank measurements, flowmeter calibrations, position records, and port call logs through to the aggregated figure in the report.
Under Article 3ge of the directive, maritime emissions are verified in accordance with the verification and accreditation rules in Chapter III of Regulation (EU) 2015/757. A verifier whose accreditation lapses or is suspended during a reporting cycle requires the affected company to engage a substitute verifier and re-issue the opinion.
The aggregated, verifier-attested figure is loaded into THETIS-MRV, and that verified figure sets the per-company EUA tonnage to be surrendered. Companies with fleets under multiple flags or in multiple commercial pools still surrender as a single legal entity.
Computing the surrender quantity
The surrender obligation is set by Article 12(3) read with Article 3ga and Article 3gb. Two inline equations govern it:
The base surrender formula is:
$$ N_{\text{EUA}} = E_{\text{verified}} \times k_{\text{phase-in}}(y) $$where \(E_{\text{verified}}\) is the per-company verified CO2-equivalent emissions in tonnes for year y across covered scope categories, and \(k_{\text{phase-in}}(y)\) is 0.40 for emissions year 2024, 0.70 for emissions year 2025, and 1.00 from emissions year 2026 onward. The phase-in factor is applied at the per-company aggregate, not per voyage.
From 2026, \(E_{\text{verified}}\) also captures CH4 and N2O converted to CO2-equivalent.
The scope rule under Article 3ga determines which emissions enter \(E_{\text{verified}}\): 50 percent of emissions on voyages between an EEA port and a non-EEA port (extra-EEA), and 100 percent of emissions on intra-EEA voyages and at-berth in EEA ports. The scope rules are detailed at /wiki/eu-ets-maritime-scope-phase-in , and the scope factor card below applies them. For an end-to-end liability estimate including phase-in, use the EUA liability card in the opening section.

A worked example: a company operates 22 vessels with verified 2025 emissions of 412,300 t CO2-equivalent. The 2025 phase-in factor is 0.70. Surrender quantity = 412,300 x 0.70 = 288,610 EUAs. At an average acquisition cost of EUR 78 per EUA, the cash exposure is EUR 22.51 million. The company executes the surrender in two registry instructions of 144,305 EUAs each on 23 and 24 September 2026.
EUA acquisition channels
Because maritime receives zero free allocation, every EUA surrendered must be bought. Three acquisition channels exist.
The EEX primary auction is held on behalf of participating Member States. The auction calendar is published months in advance. Bidding requires exchange membership or routing through an admitted intermediary; most shipping companies access the auction indirectly through an investment bank or commodity broker.
The secondary spot market clears bilaterally OTC and on EEX/ICE Endex spot order books. An EUA is a unitised, registry-tracked instrument and is fungible regardless of how it was acquired. Spot volumes are large enough that liquidity is rarely a constraint outside stress events.
The derivatives market runs primarily on EUA December futures on ICE Endex and EEX. December futures are the natural hedging instrument for a September surrender because the December y contract captures the cash-EUA basis through most of the year. At futures expiry, settlement is physical delivery of EUAs into the buyer’s holding account, making the futures economically equivalent to spot plus financing.
Most companies blend all three channels. A typical pattern: lift forward EUA cover progressively through the emissions year via futures, mark to market at year-end, settle futures into spot in late August y+1, and execute the registry surrender before 30 September. The hedging mechanics interact with the allowance allocation regime at /wiki/eu-ets-allowance-allocation-shipping .
Union Registry: the MOHA and the surrender transaction
The Union Registry, established under Commission Delegated Regulation (EU) 2019/1122 , is the Commission-operated electronic database holding every EUA and recording every transfer. National administrators in each Member State act as front-line account managers.
Each shipping company holds a Maritime Operator Holding Account (MOHA) opened with the administrator of its administering authority. The MOHA receives EUAs purchased on EEX or transferred from counterparties, and from the MOHA the company executes the surrender transaction. Account opening requires an enhanced due-diligence package on beneficial ownership.
Surrender is a two-step transaction inside the registry. First, the company ensures the required tonnage of EUAs is present in the MOHA; spot and auction transfers settle T+1 to T+3 depending on channel. Second, the company executes the surrender instruction, specifying the required tonnage. The instruction debits the MOHA and credits the central EU Surrender Account, where the EUAs are auto-cancelled immediately.
A surrender instruction once executed is irrevocable. The registry has no reversal mechanism for quantity errors where a company simply surrendered more than it owed. The registry regulation does allow correction of administrative errors (wrong account number, fraud, duress) on a narrow defined basis, but over-surrender for a quantity mistake is not in that list. Companies use a four-eye sign-off model, with the surrender instruction constructed by the carbon-compliance team and signed off by the CFO or treasurer before submission. Large companies split the surrender across multiple instructions over several days in late August or September to reduce operational risk and information leakage.
Surrender can be scheduled in advance inside the registry and executed on the target date. The deadline itself is a calendar-day deadline: if 30 September falls on a weekend, it does not roll to Monday. Companies plan the registry instruction for the last business day before 30 September that gives a comfortable margin against settlement frictions.
Short-surrender: EUR 100 indexed penalty and continuing obligation
If at the close of 30 September y+1 the company has surrendered fewer EUAs than its verified emissions require, Article 16(3) of the directive triggers two cumulative obligations.
The first is a cash penalty of EUR 100 per tonne of CO2-equivalent for which an allowance has not been surrendered. The figure is indexed for EU-wide consumer price inflation since 2013, so the effective 2026 penalty is materially higher than the nominal EUR 100 base.
The second obligation is the continuing surrender: the penalty payment does not extinguish the underlying obligation. The company must still acquire and surrender the shortfall. Member States also ensure publication of the names of shipping companies in breach of the surrender requirement under Article 16(2), and failure across two or more consecutive reporting periods opens the Article 16(11a) expulsion route.
The combined cash exposure on a short-surrender of \(N_{\text{short}}\) tonnes:
$$ \text{Cost}_{\text{short}} = N_{\text{short}} \times p_{\text{penalty}} + N_{\text{short}} \times p_{\text{EUA}} $$where \(p_{\text{penalty}}\) is the inflation-indexed per-tonne restitution rate (nominal EUR 100 base, indexed upward from 2013) and \(p_{\text{EUA}}\) is the EUA spot price at the time the company acquires the shortfall to fulfill the continuing obligation. At the 2024 average primary auction clearing price of EUR 64.74 (range EUR 49.50 to EUR 75.35), the indexed restitution rate more than doubles the total cash exposure relative to a timely surrender. The EUA liability card in the opening section shows the short-surrender outcome alongside the on-time outcome for a parametric fleet.
Article 16 enforcement: missing report, missing EUAs, false data
Article 16 of the directive, amended by Directive (EU) 2023/959, which extended Article 16(2) to shipping companies and inserted Articles 16(3a) and 16(11a), describes the administrative case the administering authority opens against a non-compliant shipping company. The enforcement chain has three triggers, and the cases are per-incident and per-emissions-year .
Missing emissions report by 31 March y+1 puts the company into a first-stage administrative case. The administering authority issues a notice, gives a remediation window, and, if the report is still not submitted, refers the case for public listing.
Missing EUAs at 30 September y+1 triggers the Article 16(3) cash penalty. The administering authority computes the shortfall against the verified emissions, levies the indexed EUR 100/t penalty, and demands the continuing surrender. If the company contests the shortfall, a Member-State-level appeal lies, but the surrender deadline does not toll during the appeal.
False or misleading emissions data invalidates the report and exposes the company to MRV Regulation administrative penalties under Article 20 plus the ETS non-surrender penalty if the corrected liability is higher. The detection pathway runs through the verifier’s reasonable-assurance opinion.
A single company that misfiles in one year and then short-surrenders the following year faces two separate administrative cases, each with its own publication and escalation track.
Public-list publication of non-compliant operators
Under Article 16(2) as amended, “Member States shall ensure the publication of the names of operators, aircraft operators and shipping companies that are in breach of requirements to surrender sufficient allowances”.
The list carries operational and reputational weight beyond the cash penalty. Charterers, lenders, P&I clubs, hull and machinery insurers, classification societies, and bunker suppliers use it as a due-diligence input. A listed company can face risk premiums on freight rates, restrictions on time-charter pools, and lender credit downgrades.
Port-state denial: Article 16(11a) expulsion order
Article 16(11a), introduced by Directive (EU) 2023/959 specifically for shipping, applies where a shipping company “has failed to comply with the surrender obligations for two or more consecutive reporting periods, and where other enforcement measures have failed to ensure compliance”. The competent authority of the Member State of the port of entry may then, after giving the company the opportunity to submit its observations, issue an expulsion order, notified to the Commission, EMSA, the other Member States and the flag State. Every Member State other than the one whose flag the ship flies then refuses entry of the ships under the company’s responsibility into any of its ports until the company fulfils its surrender obligations. The flag Member State shall detain the ship, and it may issue a flag State detention order, after which every Member State takes the same measures.
The only qualification in the text is that the order applies “without prejudice to international maritime rules applicable in the case of ships in distress”.
Port-state denial is the regulation’s most powerful enforcement lever because it directly removes the non-compliant ship from the commercial market the directive covers. A bulker barred from all EU ports cannot lift cargoes on EU charters, eliminating a substantial fraction of the global dry-bulk fixture book. The deterrent effect exceeds the cash penalty alone by a wide margin, which is why short-surrender is rare in practice despite being operationally simple to fall into.
Data flow: onboard capture through THETIS-MRV to Union Registry
The data flow from voyage to registry runs through four sequential steps.
Step A: Onboard capture. The master and engineers record noon reports, bunker delivery notes, departure and arrival fuel ROBs, flowmeter readings, voyage time and distance, and port-call logs. The approved monitoring plan defines which fuel-quantity methodology applies (Method A: BDN and periodic stock take; Method B: bunker fuel tank monitoring; Method C: flowmeters; Method D: direct CO2 measurement). Onboard data transmits to shore daily or weekly via the company’s MRV data platform.
Step B: Company aggregation and verifier review. The company aggregates per-voyage records into per-ship and per-company annual figures. The verifier conducts reasonable-assurance fieldwork on a sample of voyages, BDN reconciliations, data-system walkthroughs, and recalculations of CO2 from fuel, then issues the reasonable-assurance opinion or qualifies it.
Step C: THETIS-MRV submission. The company files the verifier-attested report into THETIS-MRV by 31 March. THETIS-MRV aggregates per-ship figures to the per-company total. The Commission makes the reported CO2 emissions information public by 30 June y+1 under Article 21(1) of Regulation (EU) 2015/757.
Step D: Union Registry surrender. The company logs into the Union Registry, confirms the MOHA holds the required tonnage, and executes the surrender instruction by 30 September. The registry debits the MOHA, credits the EU Surrender Account, and the EUAs are auto-cancelled. The registry reports per-Member-State surrender flows to the Commission’s Climate Action DG for the annual cap-utilisation report.
The four steps are loosely coupled: Steps A and B are continuous; Step C is triggered by 31 March; Step D by 30 September. Errors propagate forward: a bad noon report in Step A becomes a verifier qualification in Step B, a delayed THETIS-MRV submission in Step C, and a surrender executed against an estimated figure in Step D. Companies operating fleets above 30 to 40 vessels typically invest in dedicated MRV data platforms that automate Steps A and B and integrate with THETIS-MRV submission templates.
Administering authority structure and Member-State coordination
The administering authority is the per-company node in the enforcement chain. Each Member State designates a competent authority for ETS matters under Article 18 of the directive.
Cross-Member-State coordination matters in three scenarios. When an Article 16(11a) expulsion order is issued, it is notified to the Commission, EMSA, the other Member States and the flag State, and every Member State other than the flag State refuses entry. When a company’s administering authority changes because port-call shifts move the four-year rolling average window, the outgoing and incoming authorities transfer the open file. When a single voyage spans ports in multiple Member States and a scope-allocation dispute arises, the involved authorities jointly review the THETIS-MRV record.
Charter-party passthrough: the BIMCO ETS clause
The economic burden of EUA surrender lands on the commercial party that benefits from the voyage, not necessarily on the legal party that surrenders. The asymmetry is starkest in time charters. Under a typical NYPE or BPTIME 3 form, the time charterer pays bunkers and directs commercial employment, but the shipowner (or its ISM manager) is the Article 3(w) shipping company and surrenders the EUAs. The owner pays cash for EUAs to satisfy a liability driven by the charterer’s commercial decisions.
The BIMCO ETS - Emission Trading Scheme Allowances Clause for Time Charter Parties 2022 re-allocates this cost in kind. Throughout the charter period the charterers “provide and pay for the Emission Allowances corresponding to the Vessel’s emissions”. Within the first seven days of each month the owners notify the quantity for the previous month, with the supporting calculations and data, and within seven days of notification the charterers transfer those allowances into the owners’ nominated account. For the final month the owners notify an estimated quantity no later than 14 days before expected redelivery, and the estimate is trued up against the actual quantity, in allowances, within seven days. Allowances for off-hire periods can be offset or returned. If the charterers fail to transfer, the owners may suspend performance on five days’ notice while the vessel remains on hire. The clause has no cash option and no EUA reference price.
In voyage charters, BIMCO published three ETS clauses for voyage charter parties in 2023: the Emission Scheme Freight Clause, under which the ETS cost forms part of the freight; the Emission Scheme Surcharge Clause, a pre-agreed surcharge paid in cash; and the Emission Scheme Transfer of Allowances Clause, under which the charterers transfer allowances. The owner remains the Article 3(w) shipping company and carries the surrender obligation; the charterer bears the cost through whichever mechanism the fixture adopts.
In bareboat charters, if the bareboat charterer holds the DoC, it is the Article 3(w) shipping company and surrenders directly; no owner-to-charterer passthrough arises. If a bareboat sits inside a head time charter, the time-charter passthrough operates between the bareboat charterer and the time charterer in the usual way.
The voyage profit waterfall under maritime ETS: gross freight earned from cargo lift, less bunker cost, less port and canal dues, less cargo handling and stevedoring, less EUA pass-through liability (scope-share times verified emissions times phase-in factor times EUA price), less FuelEU compliance cost (under the intensity formula ), less other variable, equals voyage contribution. The surrender schedule card in the opening section and the three cards below cover the phase-in, FuelEU compliance balance and FuelEU penalty terms of that waterfall.

Interaction with FuelEU Maritime and IMO frameworks
The surrender cycle runs in parallel with the FuelEU Maritime Regulation , which governs annual GHG intensity of energy used onboard from 2025. FuelEU runs on a separate timeline under the balance-and-pooling regime : the verifier records pool composition by 30 April y+1, and the FuelEU document of compliance and any penalty payment fall due by 30 June y+1, three months before the ETS surrender. The two regimes share the MRV data infrastructure but apply different scope and calculation rules.
The IMO Net Zero Framework and the IMO DCS collect overlapping fuel-consumption data but operate on IMO timescales and do not create EUA surrender obligations. Data submitted to the IMO DCS is distinct from the EU MRV report and is not submitted to THETIS-MRV. Companies operating globally maintain parallel data chains: IMO DCS for flag-state and IMO reporting, EU MRV for the ETS and FuelEU surrender cycles.
The EU ETS Innovation Fund is partly funded by ETS auction revenue. Directive (EU) 2023/959 sets no maritime allowance earmark inside the fund; Article 10a(8) instead requires the Commission to give special attention to projects that decarbonise the maritime sector and to include dedicated maritime topics in Innovation Fund calls. This does not affect surrender mechanics directly but sets the policy context in which the compliance cost is recycled.
Monitoring plan: the foundation document for surrender
Every verified figure in the surrender chain starts with an approved monitoring plan under Article 6 of Regulation (EU) 2015/757 , as updated by Regulation (EU) 2023/957 . The monitoring plan is a per-company document, but it must specify the monitoring approach for each individual ship covered. It identifies the measurement methodology (Methods A through D), the data-quality control procedures, the responsible personnel, the data-flow diagrams from onboard measurement systems to the company aggregation platform, the procedures for handling gaps and corrections, and the sub-contractor arrangements for calibration and verification activities.
The verifier assesses a monitoring plan’s conformity and the administering authority approves it (Article 6(8) as amended). Any significant change to the plan, for example a switch from Method A (BDN-based) to Method C (flowmeter-based) for fuel quantification on a specific vessel, requires a plan modification assessed and approved the same way before the new methodology generates data that can be submitted to the administering authority. Unapproved changes in monitoring practice are one of the more common grounds for a verifier qualification in the annual reasonable-assurance opinion, which in turn delays the 31 March submission.
Commission Implementing Regulation (EU) 2023/2599 sets the rules for the administration of shipping companies by administering authorities; it is not a monitoring-plan template act. Plan templates are set by Commission implementing acts under Article 6(5) of the MRV Regulation as amended. Under Article 6(6), monitoring plans assessed by the verifier and reflecting the amended rules had to be submitted to the administering authority by 1 April 2024, and under Article 6(8) administering authorities approve them by 6 June 2025.
The monitoring plan also governs the treatment of gas carriers transporting LNG or LPG as fuel. For LNG carriers, the fuel slip and boil-off gas are part of the fuel-consumption calculation under Method A or C, and the monitoring plan must describe how boil-off mass is estimated across each voyage. From 2026, CH4 reporting adds a further layer: the plan must specify the CH4 fugitive-emission factor applicable to the vessel’s engine type, which the company derives from the engine-maker’s published combustion data.
Over-surrender: auto-cancellation and no refund
When a company delivers more EUAs to the surrender account than it owed, the registry auto-cancels all of them, including the excess. There is no mechanism to reclaim EUAs from the central surrender account. Once an EUA is auto-cancelled it ceases to exist; reissuing it would re-create a unit and breach the cap, so the registry regulation does not permit it.
Causes of over-surrender include arithmetic error in the registry instruction, a late data correction that should have reduced the verified emissions (and therefore the surrender quantity) but was discovered after the instruction was already executed, or an internal fleet-pool allocation that double-counted a vessel for a fractional period. The practical implication is that companies constructing the surrender instruction must reconcile the required tonnage against the registry instruction with precision before submission. A four-eye review, where the carbon-compliance team builds the instruction and the CFO or treasurer countersigns before execution, is standard practice at well-run operators.
A partial under-delivery that the company corrects with a second instruction before 30 September is accepted by the registry without penalty, provided the two instructions together sum to the required tonnage by the deadline. The registry records each instruction as a separate transaction but computes compliance against the cumulative total at the deadline.
Common operational errors
Eight errors account for most administrative cases and penalty exposures.
Confusing the 31 March emissions report deadline with the 30 September surrender deadline is the most common error. They are six months apart and the consequences of missing each are different: a late report triggers the Article 11 administrative case; a late surrender triggers the Article 16(3) cash penalty.
Computing \(E_{\text{verified}}\) on 100 percent of all voyages rather than applying the Article 3ga scope-share (50 percent for extra-EEA legs) systematically overstates the surrender obligation. Overstating leads to over-surrender, and the registry has no refund mechanism.
Applying the phase-in factor for the reporting year rather than the emissions year results in a one-year offset. The 2025 reporting year (y+1) uses the 2024 emissions year phase-in factor of 0.40, not 0.70.
Attempting to surrender from an account other than the MOHA is rejected by the registry. Only the MOHA mapped to the company’s administering authority is valid as the source account for a surrender transaction.
Executing the surrender instruction on a calendar day after 30 September because of a weekend miscount is a direct Article 16(3) trigger. The deadline does not roll to Monday if 30 September falls on a weekend.
Treating the cash penalty as extinguishing the continuing surrender obligation leaves the company with a second exposure: the missing allowances must still be delivered regardless of penalty payment.
Failing to update THETIS-MRV company attribution after a corporate restructuring leaves the wrong administering authority on the file, which can leave the obligation on the wrong entity’s file and cause the surrender to fail registry validation.
Over-surrendering, then requesting a refund of the excess, is not available. The registry auto-cancels surrendered EUAs; they cannot be recovered.
New entrants and fleet changes during the compliance year
A shipping company that acquires a vessel mid-year inherits the ETS obligation for that vessel from the date of acquisition, not from 1 January. The administering authority attributes verified emissions to the current Article 3(w) shipping company for each period. In the THETIS-MRV system, the company attribution database records an effective date for each vessel-operator pair, and the MRV report must split emissions between the selling company and the acquiring company at the transfer date.
For acquisitions, the acquiring company must open or expand its MOHA to cover the new vessel’s projected EUA liability from the acquisition date to 31 December y. The prior operator’s obligation ends at the transfer date. In practice, commercial due diligence on vessel acquisitions now includes an EU ETS exposure calculation: the buyer estimates the remaining year’s emissions for the vessel, the buyer’s and seller’s counsel negotiate the EUA adjustment at closing, and the charter-party or sale-and-purchase agreement specifies how the EUA cost is handled for the partial year.
For vessel disposals, the selling company must confirm to its administering authority that the THETIS-MRV attribution has been updated before filing its MRV report. Selling a vessel but retaining the ISM DoC until the end of the year, a common structural practice, keeps the selling company as the Article 3(w) shipping company for that vessel through year-end, meaning the surrender obligation for the full year sits with the seller. The change-of-company rule itself sits in Article 11(2) of the MRV Regulation as amended by Regulation (EU) 2023/957.
A company that enters the ETS for the first time, for example because it commissions a new vessel above 5,000 GT calling an EU port for the first time, must establish its MOHA before the vessel’s first covered voyage generates emissions. The administering authority opens the account after verifying the company’s identity and beneficial ownership. Account setup is not instant, so companies with planned new-build deliveries should apply before the first covered voyage date.
Limitations
The surrender mechanics described here reflect Directive (EU) 2023/959 and the implementing regulations as in force through mid-2026. Under Article 3gg(5) the Commission reports by 31 December 2026 on including ships, including offshore ships, below 5,000 GT but not below 400 GT, and any resulting amendment would alter the scope described. EUA prices used in worked examples are indicative and will differ materially from prices at the time of any specific surrender.
The scope rules at Article 3ga cover voyages to, from and between ports under the jurisdiction of a Member State. Vessels below 5,000 GT are outside the surrender obligation regardless of route. Offshore ships of 5,000 GT and above enter the surrender obligation from 1 January 2027.
The surrender formula presented assumes the verified emissions figure is final. In practice, corrections to MRV data after verification can revise the obligation upward or downward; the company must true up accordingly.
The BIMCO ETS clause discussed here is the 2022 edition. Later editions may modify the monthly notification and transfer periodicity or the suspension remedy; always use the current clause version for active charter negotiations.
