Operators

The 2018 public files do not name the companies managing each ship, so operator rankings start in 2024.

Who verifies the reports

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

59%
Fuel bought, corrected by tank soundings
B · Bunker tank monitoring

Notes

  • Medians and rankings use 65 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.
