EU ETS Cost Calculator
Enter the fuel a voyage burns — see the CO₂ it emits and the EU ETS allowance (EUA) cost you carry, adjusted for the phase-in year and whether the voyage touches or stays within the EEA. No account needed.
Fuel burned on the voyage
Fuel consumed (metric tonnes)
EU ETS covers ships of 5,000 GT and above from 2024. The allowance surrender phases in: 40% of emissions for 2024, 70% for 2025, 100% from 2026.
Your result
This is the cost of the EU Allowances (EUAs) you would surrender for this fuel — a real operating cost of the voyage that you can document as an expense.
The EUA price is set by the carbon market and moves daily — the number you actually pay tracks it. This band shows the range so it can be planned around, not guessed.
Estimate for planning and expense documentation only. The amount actually surrendered is settled on verified emissions; confirm the treatment with your administrator or verifier.
This is a one-off estimate.
Track your EU ETS cost voyage by voyage, feed it straight into an accounting-ready annual export, and see it alongside EU MRV, IMO DCS, CII and FuelEU — derived from the data your crew already logs. Free for shipowners.
How EU ETS works for shipping
Carbon has a price at the ship
Since 2024, shipping is inside the EU Emissions Trading System. For every tonne of CO₂ in scope, the company must surrender one EU Allowance (EUA) — bought at the market price. The cost is the CO₂ from the fuel × the EUA price × the applicable share.
The phase-in ramp
Liability was introduced gradually: 40% of in-scope emissions for 2024, 70% for 2025, and 100% from 2026 onwards. From the 2026 compliance year the full cost applies.
Geography sets the share
A voyage between two EEA ports (and time at berth in an EEA port) counts 100%. A voyage into or out of the EEA counts 50%. A voyage between two non-EEA ports is exempt. The effective liability combines this geographic share with the phase-in factor.
Frequently asked questions
Which ships and voyages does EU ETS cover?
Ships of 5,000 GT and above, any flag, calling at EEA ports — from 2024. Intra-EEA voyages and time at berth count 100% of emissions; voyages into or out of the EEA count 50%; voyages entirely outside the EEA are not covered.
How is the EUA cost calculated?
CO₂ is the fuel burned × its IMO carbon factor (VLSFO/HSFO 3.114, LSMGO/MGO 3.206, LNG 2.750 t CO₂ per t fuel). Cost = CO₂ × EUA price × geographic share × phase-in factor. This page uses those exact factors and the 2024–2026 phase-in.
Why does the EUA price matter so much?
The EUA price is set by the carbon market and is volatile — it has traded from below €60 to above €90 in recent years. Because the whole cost scales linearly with it, planning against a price band rather than a single figure is the realistic approach.
Is the EU ETS cost tax-deductible / an operating expense?
The allowance cost is an operating cost of the voyage. Our annual export documents the estimated liability so it can be recorded as an expense — but confirm the accounting treatment with your own accountant; this is not tax advice.
