The inclusion of maritime shipping in the European Union Emissions Trading System (EU ETS) marks a watershed moment for the industry. Since January 2024, shipping companies have been required to monitor, report, and surrender emission allowances for CO2 emissions from voyages within, to, and from EU and EEA ports. In 2026, the phase-in period continues — and the financial and operational implications are becoming clearer.
This article provides a practical overview of how EU ETS applies to maritime, what it costs, and what ship owners and operators should be doing to manage their obligations effectively.
How EU ETS Applies to Shipping
EU ETS covers all vessels of 5,000 GT and above that call at EU or EEA ports. The scope includes 100% of emissions from intra-EU/EEA voyages (port A in the EU to port B in the EU) and 50% of emissions from voyages between an EU/EEA port and a non-EU/EEA port (in either direction). The phase-in schedule requires companies to surrender allowances for 40% of verified emissions in 2024, 70% in 2025, and 100% from 2026 onwards.
The responsible entity — the "shipping company" for EU ETS purposes — is typically the ISM company as recorded on the Document of Compliance. This means technical managers and commercial operators need clear contractual arrangements about who bears the EU ETS cost, particularly in time charter arrangements where fuel procurement and voyage decisions rest with the charterer.
Understanding the Cost Impact
The financial impact of EU ETS depends on two variables: the volume of emissions covered and the price of EU emission allowances (EUAs). Allowance prices have fluctuated significantly, but market consensus for 2026 suggests prices in the range of EUR 60-80 per tonne of CO2. For a Capesize bulk carrier consuming 50 tonnes of fuel per day on an intra-EU voyage, this translates to a daily EU ETS cost of approximately EUR 9,000-12,000 at current allowance prices.
These costs are material. For vessel types and trades with high EU port exposure — such as container feeders, short-sea operators, and intra-Mediterranean traders — EU ETS can represent a significant addition to voyage costs. For deep-sea vessels making occasional EU port calls, the impact is more modest but still meaningful.
EU ETS is not just a compliance obligation — it is a new cost of doing business in European waters that requires strategic fuel management, voyage planning, and contractual clarity.
MRV Reporting and Verification
EU ETS maritime compliance is built on the existing EU MRV framework. Companies must have an approved Monitoring Plan, collect fuel consumption and emissions data throughout the year, and submit an annual Emissions Report to an accredited verifier. The verified report forms the basis for the allowance surrender obligation.
Data quality is critical. Errors in fuel consumption reporting, voyage categorisation (intra-EU vs. international), or port call classification can lead to over- or under-reporting of emissions — with financial consequences in both directions. Companies that invested in robust MRV reporting processes since the framework launched in 2018 are well positioned; those that treated MRV as a paperwork exercise may face challenges.
Allowance Management Strategies
Managing EU ETS allowances is a new discipline for most shipping companies. Allowances can be purchased on the spot market, through forward contracts, or at auction. The choice of procurement strategy affects both cost and cash flow. Some companies are opting for gradual purchasing throughout the year to average out price volatility. Others are hedging through forward contracts to lock in known costs.
Pooling arrangements — where multiple vessels' emissions are managed together — can also offer flexibility, allowing surplus allowances from efficient vessels to offset the obligations of less efficient ones within the same fleet.
What Ship Owners Should Do Now
If you have not already done so, ensure your MRV monitoring plan is accurate and your data collection processes are robust. Review your charter party agreements to ensure EU ETS cost allocation is clearly defined. Establish an allowance procurement strategy — or engage a specialist to manage this on your behalf. And integrate EU ETS into your broader decarbonisation planning alongside CII and FuelEU Maritime obligations.
