What EU carbon rules actually cost on a 2026 ocean freight booking

EU ETS maritime: what is actually being surrendered in 2026

Directive (EU) 2023/959, which amended Directive 2003/87/EC to bring maritime transport into the EU Emissions Trading System, has applied to cargo and passenger ships of 5,000 gross tonnage and above calling at EU or EEA ports since 1 January 2024, regardless of flag state. Offshore ships of the same size only entered monitoring obligations from 1 January 2025 and move into full allowance-surrender scope from 2027.

The surrender obligation phases in by emissions year, not by calendar year of surrender. Carriers surrendered allowances covering 40% of verified 2024 emissions by 30 September 2025. The deadline that actually falls inside 2026 is the surrender of allowances covering 70% of verified 2025 emissions, due by 30 September 2026. From 2026 emissions onward the obligation is 100%, with the first full-year surrender due by 30 September 2027. This is a later deadline than the general EU ETS's 30 April date for stationary installations.

Scope within a voyage also matters for how much of a shipment's emissions count. Emissions from a voyage that runs entirely between two EU or EEA ports, and emissions generated while a ship is at berth in an EU or EEA port, count at 100%. A voyage that starts or ends outside the EU or EEA, which covers most produce and packhouse exports moving to European buyers, counts at only 50% of the voyage's emissions. 2026 is also the first year methane and nitrous oxide count toward the obligation alongside carbon dioxide; only CO2 counted in 2024 and 2025.

The specific article numbers commonly cited for these mechanics, Article 3ga for scope and Article 3gb for the phase-in, come from secondary sources including the European Commission's own programme pages, DNV and ICAP; we could not fetch EUR-Lex's primary text for Directive (EU) 2023/959 in this research pass, every route returned an empty anti-bot response, so treat the article numbers themselves as reported but unverified against primary legal text, even though the percentages, dates and thresholds are independently corroborated across multiple sources with no conflicts found.

FuelEU Maritime: the 2026 compliance calendar

Regulation (EU) 2023/1805, FuelEU Maritime, has applied in full since 1 January 2025, with its monitoring-plan provisions taking effect from August 2024. It runs on an annual cycle, and 2026 is the first full compliance year to work through that cycle end to end. A ship's report covering the 2025 reporting period is due to its verifier by 31 January 2026. The verified report must be recorded in the FuelEU database by 31 March 2026. The resulting compliance balance is approved, and any flexibility mechanism applied, by 30 April 2026. The FuelEU Document of Compliance, which the ship must carry on board, is then issued by 30 June 2026. These dates are consistent across Lloyd's Register and other classification-society sources, though we could not independently confirm them against EUR-Lex primary text.

The regulation's core requirement is a reduction in the GHG intensity of a ship's energy mix against a 2020 reference value of 91.16 gCO2eq per MJ. The reduction required is 2% from 2025, rising to 6% from 2030, 14.5% from 2035, 31% from 2040, 62% from 2045 and 80% from 2050. This trajectory is independently confirmed across EMSA, UK P&I, Lloyd's Register and several classification societies; it is a wholly separate mechanic from EU ETS maritime's phase-in of the emissions share requiring allowance surrender, and the two should not be read as versions of the same schedule.

A ship that falls short of its GHG-intensity target faces a penalty calculated against a reference cost of 2,400 euros per tonne of VLSFO-equivalent energy, with a multiplier of 1 plus (n minus 1) divided by 10 for each consecutive non-compliant reporting period, under Article 23(2) and Annex IV. A separate penalty applies to onshore power supply non-compliance at berth, reported at 1.50 euros per kWh of a ship's established electrical power demand multiplied by non-compliant hours, though that obligation itself only becomes mandatory for container and passenger ships over 5,000 GT at TEN-T ports from 1 January 2030. Both figures are corroborated by maritime-compliance consultancies rather than confirmed against EUR-Lex directly.

Ships can also manage a deficit through the flexibility mechanisms in the regulation, and the detail here is worth getting right because it is widely paraphrased loosely. Article 20 covers both banking and borrowing: banking carries a compliance surplus forward, while borrowing under Article 20(2) lets a ship draw an advance surplus from the following reporting period. The cap on that advance is 2%, but it is measured against the current deficit period's Article 4(2) intensity limit multiplied by the ship's energy consumption, not against the following period's target, and a ship may not borrow in two consecutive reporting periods. What is borrowed is repaid out of the following period's balance multiplied by 1.1, an effective 10% surcharge. Pooling sits separately in Article 21: two or more ships combine their compliance balances, each ship may join only one pool per period, and Article 21(7) disapplies Article 20(2) to a pooled ship, so borrowing and pooling cannot be used together in the same period.

The penalty is formulaic rather than discretionary. Annex IV, Part A, referenced from Article 23(2), sets the FuelEU penalty as the absolute compliance deficit in gCO2eq divided by 41,000, the megajoules treated as one tonne of VLSFO equivalent, multiplied by EUR 2,400 per equivalent tonne. Article 23(2) then escalates it for repeat non-compliance: a ship in deficit for two or more consecutive reporting periods has the amount multiplied by one plus (n minus one) divided by ten, where n is the number of consecutive deficit periods.

The IMO Net-Zero Framework: approved, not adopted, no date to enter into force

This is the strand most likely to be reported wrong on an invoice or in a broker's briefing, so the sequence matters. At MEPC 83 in April 2025, the IMO's Marine Environment Protection Committee approved draft MARPOL Annex VI amendments establishing a new Chapter 5, the Net-Zero Framework, combining a global fuel standard with a GHG pricing mechanism. Approval is not adoption; the IMO's own press briefing at the time quoted the Secretary-General describing the next step as creating the conditions for successful adoption.

An extraordinary session, MEPC/ES.2, convened in October 2025 specifically to adopt the framework, and it did not. The IMO's own press briefing confirms the session was adjourned, with talks set to resume within twelve months. The widely reported vote tally on adjournment, 57 in favour, 49 against and 21 abstentions, does not appear on any imo.org page we found and should be treated as trade-press-sourced, not IMO-confirmed.

MEPC 84 met from 27 April to 1 May 2026 and did not adopt the framework either, and it set no adoption date at that session. It did adopt unrelated items, including a new North-East Atlantic emission control area and a 2026 marine plastic litter strategy, and agreed two further intersessional working-group meetings before MEPC 85. What MEPC 84 did establish, confirmed directly on imo.org, is that the Committee will resume the Second Extraordinary Session on Friday 4 December 2026, subject to confirmation by MEPC 85, which is scheduled for 30 November to 3 December 2026. That confirmation had not happened as of 4 September 2026, the date of this piece.

The practical reading for an exporter: as of today, the Net-Zero Framework has no legal force and no entry-into-force date, and stating one, including the previously circulated 2027 figure from before the October 2025 adjournment, would be speculation. A carrier that itemises an IMO carbon charge on a 2026 invoice is pricing in an anticipated future obligation. That is a legitimate commercial choice on the carrier's part, but it is categorically different from EU ETS maritime or FuelEU Maritime charges, which fund an obligation the carrier is already legally required to meet.

Comparing the three instruments

The table below keeps the three separate on purpose, since conflating them is the most common error we see in freight quotes and in exporter questions about a surcharge line.

What to ask a carrier or forwarder about a surcharge line

When a quote or invoice includes a carbon-related line, ask which of the three instruments it funds, and ask the carrier to name the instrument and article, not just say "environmental surcharge" or "emissions fee." A genuine EU ETS pass-through should reference Directive (EU) 2023/959 and should scale with the share of the voyage inside the EEA, since only 50% of an extra-EEA voyage's emissions count toward the surrender obligation; a flat per-container fee applied identically to an EU-only move and a transpacific-to-EU move is a signal the charge is not actually cost-linked to the ETS mechanic. A genuine FuelEU-linked charge should reference Regulation (EU) 2023/1805 and typically reflects a carrier's fuel-mix compliance position rather than a fixed per-shipment rate.

Any charge attributed to "IMO carbon pricing," a "global carbon levy" or similar language should be treated as anticipatory pricing, not a pass-through, and it is reasonable to ask the carrier directly whether the charge funds a currently-owed obligation or a projected future one. This distinction also matters for how you build landed cost on a quote: an EU ETS or FuelEU charge is a real, recurring input to the freight line, while an IMO-framework charge should be treated as a variable the carrier may need to unwind or restate once, and if, the framework is actually adopted. If a carrier's rate sheet bundles a carbon charge into a general surcharge category with congestion or fuel adjustments, ask for it to be broken out; regulatory carbon costs and market-driven surcharges move on different schedules and for different reasons, and bundling them makes it harder to check either one against the underlying rule.
