Ro-pax ships, 2019
404 ro-pax ships reported to THETIS-MRV for 2019, emitting 14.9 Mt of CO₂. Efficiency is measured as g CO₂/pax·nm and, for freight, g CO₂/t·nm freight.
Ro-pax ships carry passengers and freight, and THETIS reports CO₂ per transport work for each: per passenger-mile and per tonne-mile of freight. A freight-heavy ferry looks poor per passenger and good per tonne, a passenger-heavy one the other way round, so both are shown. Passenger figures stay the benchmark for allowance gaps.

Operators
The 2019 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.

Share of 354 emission reports that name a method; a report can name several.
Notes
- Medians and rankings use 394 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.
