2023 at a glance
From the 2023 THETIS-MRV report.
Within the passenger fleet, 2024
Set against all 202 passenger ships with a full-year 2024 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, 2023
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 ports51%
- From the EU16%
- Into the EU16%
- At berth in the EU17%
Over the years
Full-year reports only. The Passenger median is the middle ship of all passenger 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→2024 | −0.7 kn | −4% | −8% | −40% | −3% | 0.7 kn slower, fuel per mile down 4%; worse than speed alone explains (fouling, weather, loading or trade). |
| 2022→2023 | +2.4 kn | −10% | +7% | −4% | −35% | 2.4 kn faster, fuel per mile down 10%; better than speed alone explains (hull, engine or trade). |
| 2021→2022 | −0.2 kn | −4% | −6% | +648% | −25% | Same speed, fuel per mile down 4%; in line with the speed change. |
| 2020→2021 | −1.8 kn | +19% | +4% | +1,776% | +120% | 1.8 kn slower, fuel per mile up 19%; worse than speed alone explains (fouling, weather, loading or trade). |
| 2019→2020 | −0.3 kn | −13% | −15% | −99% | −16% | Same speed, fuel per mile down 13%; better than speed alone explains (hull, engine or trade). |
| 2018→2019 | −0.2 kn | −5% | −6% | −37% | +3% | Same speed, fuel per mile down 5%; in line with the speed change. |
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. Passenger ships are benchmarked on CO₂ per transport work (pax) (TW), in g CO₂/pax·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 passenger 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.
