461 vehicle carrier ships reported to THETIS-MRV for 2023, emitting 4.2 Mt of CO₂. Efficiency is measured as g CO₂/t·nm.
The segment at a glance
Operators
The 2023 public files do not name the companies managing each ship, so operator rankings start in 2024.
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: ~2,683 t107 g CO₂/t·nm
- Q2: ~4,722 t67 g CO₂/t·nm
- Q3: ~5,948 t56.4 g CO₂/t·nm
- Q4: ~6,999 t48 g CO₂/t·nm
- Q5: ~8,403 t39.8 g CO₂/t·nm
Q1 to Q5 split the fleet into fifths by average cargo carried, derived from the published ratios.

How fuel is measured
Each ship's monitoring plan names one or more of the four MRV methods.

Notes
- Medians and rankings use 417 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.
