Estimate the EU Emissions Trading System exposure for any vessel, by year, based on annual fuel consumption and operating profile. Adjust the inputs to see the number live — and to understand which retrofits would move it most.

Your vessel's EU ETS exposure for the selected year.
Indicative estimate. Excludes FuelEU Maritime penalties, voyage-specific 50%/100% splits, derogations for inter-island services, and free-allowance treatment for ice-class & small-vessel operators. Verify with your verifier before financial planning.
EU ETS for shipping took effect on 1 January 2024. It applies to vessels above 5 000 GT, on a phase-in schedule: 40% of verified emissions in 2024, 70% in 2025, then 100% from 2026 onwards. Every tonne of CO₂ requires one EU Allowance (EUA), traded on the EU carbon market.
Coverage of a voyage depends on its end-points. Voyages between two EU ports count at 100%. Voyages between an EU port and a non-EU port count at 50%. Emissions while at berth in an EU port count at 100%. Voyages entirely outside the EU are not covered.
The calculator multiplies four numbers together. Annual fuel (in tonnes) × emission factor for that fuel (in tonnes CO₂ per tonne fuel) × your EU operations share × the phase-in factor for the chosen year. That gives the EUAs you need to surrender. Multiply by the EUA market price for the euro cost.
What's not included. This estimator covers EU ETS only — it does not calculate FuelEU Maritime penalties (a separate regulation, charging €2 400 per tonne of VLSFO-equivalent for vessels exceeding GHG-intensity targets). Free allowances for specific vessel classes and derogations for inter-island and outermost-region services are not modelled.
Use as a starting point. The number on the right is intended to size the decision — to help you understand the order-of-magnitude impact of retrofits, alternative fuels, route changes, or compliance strategies. For audited figures, work with your accredited verifier — Ortech Marine partners with Normec Verifavia for this.
