Operators

The 2018 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 to Q5 split the fleet into fifths by average cargo carried, derived from the published ratios.

Who verifies the reports

Accredited verifiers check each ship's MRV report. Their share of the segment's ships and CO₂.

How fuel is measured

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

Fuel bought, corrected by tank soundings
B · Bunker tank monitoring
19%
Tank readings on board
C · Flow meters

Notes

  • Medians and rankings use 434 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.
