EU shipping emissions, 2025

Every ship over 5,000 GT calling at EU and EEA ports reports its fuel and emissions to THETIS-MRV, and from 2025 also general cargo ships of 400 to 5,000 GT and offshore ships from 400 GT. This view reads all 18,946 public reports for 2025. The technical view shows how ships perform; the commercial view puts a price on it through the EU Emissions Trading System.

How wide the performance gap is

Spread of CO₂ per transport work within each segment, on each segment's own basis (cargo, pax, volume or dwt). The box holds the middle half of the fleet, the line runs from the best 10% to the worst 10%.

How to read it. Take container ships: the median ship emits 16.3 g CO₂/t·nm. Half the fleet sits inside the box, between 0.6× and 1.8× of that. The best 10% are below 0.4×, the worst 10% above 2.9×. Left of the median is better. The longer the bar, the bigger the gap between the best and worst ships in that segment.

Much of this spread is ship size, not operation: bigger ships move a tonne of cargo for less fuel. The next chart separates the two for container ships.

Size explains most of the container gap

Container ships grouped by the average cargo they carried (derived from CO₂ per mile and per tonne-mile). Within a band the spread narrows sharply.

Efficiency trend by segment

Median CO₂ per transport work of each segment, indexed to 2018 = 100. Lower is better. CO₂eq is reported only from 2024, so the trend stays on CO₂.

Note on 2025: from 2025 the EU MRV Regulation also covers general cargo ships of 400–5,000 GT and offshore ships from 400 GT. Small ships emit more CO₂ per tonne-mile, so to compare like with like the 2025 median for general cargo uses only the 1,199 of 2,706 ships that also reported in 2024, the last year of the old scope.

Fuel fingerprint: who burns LNG

Burning LNG lowers the CO₂ released per tonne of fuel. Ships whose ratio sits well below oil's 3.1 are counted here.

In 2025, 342 of them were LNG carriers and 133 container ships.

What we exclude, and why

Benchmarks use 14,194 full-year reports. Part-year reports (1,533, usually a change of company) and ships reporting no fuel (2,470) count towards totals only.
Each segment is measured by its own CO₂ per transport work: per passenger-mile for passenger ships, per cubic-metre-mile for LNG carriers and con-ros, per deadweight-mile for general cargo, per tonne-mile for the rest.
The worst 1% per segment and implausibly low values (under half the best 1%) are trimmed as reporting errors.
Distance, speed and cargo carried are derived from the published ratios; THETIS has no distance or deadweight column.
Allowances: 70% of the CO₂ in ETS scope for 2025. Offshore ships are excluded until 2027. Euro figures use the EUA price you set, default €75/t.
