2022 at a glance
From the 2022 THETIS-MRV report. Carries about 4,371 t of cargo on average.
Within the vehicle carrier fleet, 2023
Set against all 417 vehicle carrier ships with a full-year 2023 report. Bigger ships burn more per mile but less per tonne of cargo, so read fuel per mile with the ship's size in mind.
Where the emissions happen, 2022
THETIS splits each ship's CO₂ by voyage type. The split sets how much falls under the EU ETS: all of it within the EU and at berth, half of it on voyages into or out of the EU.
- Between EU ports29%
- From the EU34%
- Into the EU29%
- At berth in the EU7%
Over the years
Full-year reports only. The Vehicle carrier median is the middle ship of all vehicle carrier ships reporting that year; it moves with the fleet, so a ship can gain on it without changing itself.

Year on year
| Year | Average speed | Fuel kg/nm | Fuel per day at sea | Distance | CO₂ per transport work | Reading |
|---|---|---|---|---|---|---|
| 2023→2025 | – | – | – | – | – | |
| 2022→2023 | −1.1 kn | +17% | +7% | −82% | +38% | 1.1 kn slower, fuel per mile up 17%; worse than speed alone explains (fouling, weather, loading or trade). |
| 2019→2022 | −4.5 kn | −15% | −37% | −47% | +49% | 4.5 kn slower, fuel per mile down 15%; worse than speed alone explains (fouling, weather, loading or trade). |
Fuel per mile rises roughly with the square of speed for a given ship, so a change in speed explains much of a change in fuel per mile.
Every reporting year
One row per THETIS-MRV report. A ship that changed operator during a year has a part-year report for each.

Fuel per mile and CO₂ per tonne-mile are the ship's own reported KPIs. Vehicle carrier ships are benchmarked on CO₂ per transport work (cargo) (TW), in g CO₂/t·nm. CO₂eq adds methane and nitrous oxide and is in the public files from 2024. Rank counts from the lowest figure among that year's vehicle carrier ships. Methods: A delivery notes, B tank monitoring, C flow meters, D direct measurement. FuelEU GHG intensity is not shown: it needs fuel types, which the public file does not carry. Operators are named only from 2024, the first year the public files carry them; earlier years belong to the ship, not to any company.
