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 2024 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 2024 report it verified.
