Within the oil tanker fleet, 2025

Set against all 1,665 oil tanker ships with a full-year 2025 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, 2025

THETIS splits each ship's emissions 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 ports5%
From the EU32%
Into the EU54%
At berth in the EU10%

57% of this ship's CO₂ falls under the EU ETS (12,537 t).

Not reported

CO₂ at berth

2,089 t

9.5% of the ship's CO₂, alongside in EU ports

Methane (CH₄)

0.4 t

Mainly from LNG; small for oil, biofuel and methanol

CO₂eq uplift

+341 t

+1.6% CO₂eq on top of CO₂ alone, from CH₄ and N₂O; counted in full from 2026

Over the years

Full-year reports only. The Oil tanker median is the middle ship of all oil tanker 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
2024→2025	+0.3 kn	+1%	+4%	+208%	+20%	Same speed, fuel per mile flat; better than speed alone explains (hull, engine or trade).
2021→2024	−0.2 kn	+4%	+2%	−37%	+13%	Same speed, fuel per mile up 4%; worse than speed alone explains (fouling, weather, loading or trade).
2020→2021	+1.1 kn	−16%	−7%	−17%	−27%	1.1 kn faster, fuel per mile down 16%; better than speed alone explains (hull, engine or trade).
2019→2020	+1.5 kn	−8%	+8%	+404%	−7%	1.5 kn faster, fuel per mile down 8%; better than speed alone explains (hull, engine 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. Oil tanker 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 oil tanker 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.
