- vs segment median :
- CO₂ per transport work against the median segment ship. Below 0% is better.
- vs similar-size ships :
- CO₂ per transport work of the median ship, against the median ship of the same size band in its segment (whole segment where the segment has no size bands). Below 0% is better.
EU ETS allowances are not a tax: companies buy and surrender one allowance per tonne of CO₂ in scope. Figures use the 2025 phase-in share and an EUA price of €75 per tonne, which the commercial view lets you change. The flag is estimated from the port of registry; see the Flags page.

Verifiers of the 2025 emission reports of Denmark-flagged ships, by CO₂ verified. A ship has one verifier per report.
