Side by side

All 2025 reports of each operator, across every ship type. Change is against 2024 where the operator reported then.

Fuel per mile and speed depend on ship size and type; compare them within a segment below. A ship whose year was split between two verifiers counts for both, so verifier shares can add up to slightly more than 100%.

Share of each ship type

Share of each segment's ships whose 2025 report the verifier checked. Hover a bar for its share of the segment's CO₂.

Who works with each verifier

Groups (or ISM companies outside a group) by the number of their ships the verifier checked. “Of fleet” is the share of that operator's ships it verifies; below 100% means the operator also uses other verifiers.

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.
