Operators
The 2023 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.

How fuel is measured
Each ship's monitoring plan names one or more of the four MRV methods.
A · Bunker delivery notes
80%
Fuel bought, corrected by tank soundings
B · Bunker tank monitoring
40%
Tank readings on board
C · Flow meters
10%
Meters on the fuel lines to engines and boilers

Notes
- Medians and rankings use 9 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.
