Fuel per mile and speed depend on ship size and type; compare them within a segment below.
Segment by segment
Efficiency only compares within a ship type. Each row gives the CO₂ per transport work of an operator's typical (median) ship, and the bar sets it against the typical ship of the whole segment: to the left of the line it emits less CO₂ for the same transport work, to the right more.

NORSTAR SHIP MANAGEMENT PTE LTD: ships furthest from their peers
Each ship's CO₂ per transport work against the median ship of its type and size band. +100% means the ship emits twice as much CO₂ for the same transport work as a typical ship of its size. Ro-pax ships show passenger figures, with freight underneath.

30 of 9 reports shown. A high ratio can mean an older or faster-sailing ship, short trades with much time manoeuvring, or part-loaded voyages; it marks where to look first.
Notes
- Companies are ISM companies (Document of Compliance holders) as named in THETIS, usually the ship manager.
- Groups combine ISM companies matched on name and known ownership. If a company is in the wrong group, tell us at info@navalyze.com.
- Efficiency figures use full-year reports with fuel; totals include part-year reports.
- Euro figures use the EUA price set at the top of the page.
- Verifier names vary by entity and year (for example DNV AS and DNV Hellas); they are rolled up into one brand. A verifier's figures cover the ships whose 2025 report it verified.
