Within the chemical tanker fleet, 2024

Set against all 1,274 chemical tanker 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, 2024

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 ports0%
From the EU69%
Into the EU29%
At berth in the EU1%

51% of this ship's CO₂ falls under the EU ETS (1,555 t).

Fuel burned laden

Not reported

CO₂ at berth

44 t

1.4% of the ship's CO₂, alongside in EU ports

Methane (CH₄)

0.1 t

Mainly from LNG; small for oil, biofuel and methanol

CO₂eq uplift

+48 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 Chemical tanker median is the middle ship of all chemical tanker ships reporting that year; it moves with the fleet, so a ship can gain on it without changing itself.

2023→2024	−2.4 kn	+40%	+10%	−5%	+31%	2.4 kn slower, fuel per mile up 40%; worse than speed alone explains (fouling, weather, loading or trade).
2022→2023	+1.0 kn	−4%	+5%	+2%	+42%	1.0 kn faster, fuel per mile down 4%; better than speed alone explains (hull, engine or trade).
2021→2022	−0.8 kn	+4%	−4%	−65%	−41%	0.8 kn slower, fuel per mile up 4%; worse than speed alone explains (fouling, weather, loading or trade).
2020→2021	−0.1 kn	−1%	−2%	−20%	−22%	Same speed, fuel per mile flat.
2019→2020	+3.2 kn	−4%	+35%	+10%	+34%	3.2 kn faster, fuel per mile down 4%; better than speed alone explains (hull, engine or trade).
2018→2019	+1.5 kn	−1%	+22%	+17%	+36%	1.5 kn faster, fuel per mile flat; 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.

Fuel per mile and CO₂ per tonne-mile are the ship's own reported KPIs. Chemical 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 chemical 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.
