Brussels is deciding whether your yacht joins the carbon market

What is decided today

Since January 2024 the EU Emissions Trading System has applied to commercial cargo and passenger ships of 5,000 GT and above calling at European ports, and the European Commission confirms the machine is still phasing in: allowances covered 40 per cent of 2024 emissions, cover 70 per cent of 2025 emissions this year, and reach 100 per cent from 2027. Methane and nitrous oxide joined carbon dioxide in scope on 1 January 2026. As maritime lawyer Christoph Schliessmann noted in SuperyachtNews in January 2026, that 5,000 GT threshold leaves most yachts, private or commercial, outside the scheme.

The perimeter is already moving. Since 1 January 2025, general cargo ships of 400 to 5,000 GT and offshore ships above 400 GT must monitor and report their emissions under the EU's MRV regime, though they surrender no allowances, and offshore ships of 5,000 GT and above enter the ETS proper in 2027, per the Commission's published guidance. Below 5,000 GT, no yacht pays for carbon today - that much is decided.

The 400 GT review clause

Article 3gg of the ETS Directive requires the Commission to report to the European Parliament and the Council of the European Union by 31 December 2026 on the feasibility and the economic, environmental and social impacts of bringing vessels below 5,000 GT but not below 400 GT into the system. The binding text, as consolidated on EUR-Lex, is wider than the Commission's own FAQ suggests: the FAQ speaks of offshore and general cargo ships in that band, with 2028 floated as a possible start, while the directive itself says "ships, including offshore ships" - every type, yachts included - and allows the report to arrive with legislative proposals attached.

The groundwork already exists. In March 2025 the Commission published its review of the maritime MRV regulation, COM(2025) 109, which counted 8,525 vessels of 400 to 4,999 GT calling at EU ports in 2023 - among them 896 yachts with an estimated 1.45 million tonnes of CO2 - and set out three extension scenarios, the widest of which explicitly reaches yacht voyages not operated commercially. That report judged monitoring alone a poor bargain, with administrative cost per tonne roughly seven times that of the big-ship fleet, yet concluded the balance most likely turns positive once smaller vessels feed into the ETS, and handed that judgement to the 2026 review.

What owners should watch

The calendar is the first discipline: the report lands by the end of this year, and any actual extension would still need a legislative proposal and passage through Parliament and Council, which is why the Commission's guidance treats 2028 as the earliest conceivable start for the band. When the report comes, read two things before anything else: whether a proposal is attached, and where it draws the commercial line. Two of the three scenarios in COM(2025) 109 turn on whether a vessel carries passengers for commercial purposes - the hinge on which a chartering 500 GT yacht swings into scope.

There is also a side door: the same Commission report notes that Austria, the Netherlands and Sweden have already chosen to bring some smaller vessels or inland navigation into ETS2, the parallel carbon market, so flag and itinerary can matter before any EU-wide rule does. The homework is cheap by yacht standards - Schliessmann's checklist in SuperyachtNews runs to confirming passenger-ship status, upgrading monitoring plans to three gases and hard-wiring fuel documentation into charter and bunker contracts, and the Commission itself prices recurring MRV compliance at EUR 3,690 a year per vessel. The review will not cost an owner a euro in 2026. But the fleet has now been counted, and what Brussels counts, Brussels tends to price.
