Efficiency by ship size
Bigger ships move a tonne of cargo for less fuel, so ships are compared within size bands. Each row is drawn against the segment median.
- Q1: ~1,228 t144 g CO₂/t·nm
- Q2: ~3,517 t67.4 g CO₂/t·nm
- Q3: ~4,654 t57.1 g CO₂/t·nm
- Q4: ~5,876 t46.5 g CO₂/t·nm
- Q5: ~8,113 t43 g CO₂/t·nm
Q1 to Q5 split the fleet into fifths by average cargo carried, derived from the published ratios.

Notes
- Medians and rankings use 109 full-year reports with fuel; part-year and zero-fuel reports count towards totals only.
- THETIS reports time at sea on EU-scope voyages only, not time in port. CO₂ at berth is the closest measure of port activity it publishes.
- Speed and distance are derived from the published ratios; THETIS has no distance column.
