SEVEN SISTERS against its type
Built in 2006, it is 6 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 18,940 gross tonnage it is smaller than 57% of the other 470 ro-pax ships with a recorded tonnage. It is one of 27 ro-pax ships here under the France flag, 5.5% of the 493 on the register. The same builder is recorded for 33 other vessels here, 16 of them ro-pax ships. DFDS Seaways is linked to 5 vessels on this register. The returns for 2018–2025 all give Dieppe as port of registry.
Its 20,792 t of CO₂ for 2025 is 31% below the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 355.2 kg CO₂, 24% below the type median of 467.6 kg. It logged 4,063 hours at sea against a median of 4,243 hours for its type that year. 2.8% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 8 years with reported emissions, the highest was 2022 (22,315 t) and the lowest 2020 (14,928 t). Of the 6 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2018
Position 13 of 18 qualifying ro-pax ships by EEOI, at the 71st percentile. The dashed line is the type median, 335.9; this vessel reported 445.6.
Across the 3 ranked vessels operated by DFDS Seaways, the median percentile is 65. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 12,349,344 passenger-miles over 56,363 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 2.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 8.0% and CO₂ per nautical mile fell 2.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
