On September 30, 2025, shipping companies faced their first deadline to surrender carbon allowances under the EU ETS maritime scheme, covering 40% of verified 2024 emissions for vessels above 5,000 gross tonnage (GT). It is the system's first real test, one that expands in coverage every year through 2027, and Europe's yachting industry is starting to do the maths on what it costs.

What fell due on September 30
The September 30, 2025 deadline marked the first mandatory allowance surrender under the EU ETS maritime scheme — the European carbon trading system extended to shipping. Companies operating vessels above 5,000 GT had to surrender allowances covering 40% of their verified 2024 emissions. It is not the final deadline: it is only the first slice of a system built to grow year after year.
How the EU ETS maritime scheme works, in short
The EU ETS maritime scheme requires operators of large ships and yachts calling at European Union ports to buy and surrender emissions allowances proportional to the CO2 they actually emit. We covered how the broader system works and how it reached yachting in EU ETS: How Europe's Carbon Bill Reaches Yachting; this piece focuses specifically on what happened at the system's first real deadline, in September 2025.
The phase-in schedule through 2027
The EU ETS maritime scheme is deliberately progressive: emissions coverage rises each year until it reaches 100%, giving companies time to adapt rather than facing a single cost shock.
| Reference year | Required emissions coverage | What it means |
|---|---|---|
| 2024 (paid in 2025) | 40% | First deadline, due September 30, 2025 |
| 2025 (due in 2026) | 70% | Already set under the scheme's official schedule |
| From 2027 onward | 100% | Full coverage of verified emissions |
That ramp-up curve is the most important number for anyone planning long-term operations in Europe: compliance cost in 2025 is only a fraction of what will be charged from 2027 onward, once the system reaches full coverage.
Who is affected: the 5,000 GT cut-off
The 5,000 gross tonnage (GT) cut-off determines which vessels fall under the system. In practice, that threshold captures most of the genuinely large superyachts — the same ones that show up at Monaco and Cannes measuring tens of metres — while leaving out the vast majority of mid-size leisure boats operating in the Mediterranean or along the Brazilian coast. For a superyacht charter operator, that means folding carbon-allowance cost into season planning, something that already directly touches vessels in the size range that circulates through the luxury charter market.
The industry is already responding: hydrogen and other alternatives
Regulatory pressure and rising compliance costs help explain why shipyards are already investing in alternative propulsion ahead of any mandate. In July 2025, Boat International reported that Breakthrough, Feadship's 118.8-metre hydrogen fuel-cell superyacht, became the first superyacht supplied with liquid hydrogen, in a bunkering milestone carried out in the Netherlands in June 2025. Yachts like this directly reduce exposure to the EU ETS carbon cost, because they eliminate much of the emissions the system prices.
What this means for Brazil and Mediterranean charter
The EU ETS maritime scheme is a European Union regulation that applies to vessels calling at EU ports — it does not directly affect boat rental on the Brazilian coast, which remains outside the system's scope. The impact reaches a Brazilian client through a different channel: anyone chartering a superyacht in the Mediterranean through Voguer Yachts may see part of the carbon cost passed through into charter rates over the coming years, as coverage climbs to 70% in 2026 and reaches 100% in 2027. For anyone renting a speedboat or yacht in Brazil through Voguer, the European regulation simply does not apply.
FAQ
What fell due on September 30, 2025 under the EU ETS maritime scheme? The deadline for shipping companies to surrender their first emissions allowances, covering 40% of verified 2024 emissions, for vessels above 5,000 gross tonnage (GT).
What is the EU ETS maritime scheme? It is the extension of Europe's carbon allowance trading system to shipping, requiring operators of large vessels calling at European Union ports to buy and surrender allowances proportional to the CO2 they produce.
Which vessels are covered by the EU ETS maritime scheme? Vessels above 5,000 gross tonnage (GT) operating at European Union ports. That cut-off captures most large superyachts but excludes the majority of mid-size leisure boats.
How will emissions coverage increase in the coming years? From 40% of 2024 emissions (paid in 2025), the system rises to 70% of 2025 emissions due in 2026, under its official schedule, reaching full 100% coverage from 2027 onward.
Does the EU ETS maritime scheme affect boat rental in Brazil? Not directly. It is a European Union regulation applying to vessels calling at EU ports. Renting a speedboat, yacht or sailboat along the Brazilian coast falls outside the system's scope.
Does the EU ETS maritime scheme affect the cost of chartering a superyacht in the Mediterranean? It can, gradually. As required emissions coverage rises — from 40% in 2025 to 70% in 2026 and 100% in 2027 — part of companies' compliance cost tends to be passed through into charter rates in subsequent years.
Are shipyards already responding to carbon pressure? Yes. In July 2025, Feadship confirmed that its 118.8-metre hydrogen-powered superyacht, Breakthrough, was supplied with liquid hydrogen in the Netherlands in June — a milestone that directly reduces this type of vessel's exposure to the system's carbon cost.
