Within the ro-pax fleet, 2023

Set against all 386 ro-pax 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, 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.

Over the years

Full-year reports only. The Ro-pax median is the middle ship of all ro-pax ships reporting that year; it moves with the fleet, so a ship can gain on it without changing itself.

Year on year

Year	Speed	Fuel per mile	Fuel per day	Distance	CO₂ per TW	Reading
2022→2023	+1.7 kn	−15%	−3%	+251%	+13%	1.7 kn faster, fuel per mile down 15%; better than speed alone explains (hull, engine or trade).
2021→2022	−1.5 kn	+11%	−2%	−54%	+0%	1.5 kn slower, fuel per mile up 11%; worse than speed alone explains (fouling, weather, loading or trade).
2020→2021	+0.2 kn	+0%	+2%	−1%	−2%	Same speed, fuel per mile flat.
2019→2020	−0.5 kn	+15%	+11%	−37%	+26%	0.5 kn slower, fuel per mile up 15%; worse than speed alone explains (fouling, weather, loading or trade).
2018→2019	+0.5 kn	+1%	+5%	−11%	−48%	0.5 kn faster, fuel per mile flat; better than speed alone explains (hull, engine or trade).

Part-year reports are left out of these comparisons. 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. Ro-pax ships are benchmarked on CO₂ per transport work (pax) (TW), in g CO₂/pax·nm, and also per tonne of freight (g CO₂/t·nm freight). CO₂eq adds methane and nitrous oxide and is in the public files from 2024. Rank counts from the lowest figure among that year's ro-pax 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.
