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

Notes
- Medians and rankings use 197 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.
