CROWN SEAWAYS against its type
Built in 1994, it is 6 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 35,498 gross tonnage it is larger than 80% of the other 470 ro-pax ships with a recorded tonnage. It is one of 29 ro-pax ships here under the Denmark flag, 5.9% of the 493 on the register. The same builder is recorded for 56 other vessels here, 4 of them ro-pax ships. DFDS is linked to 6 vessels on this register. Its MRV returns name it CROWN SEAWAYS for 2018–2024 and NORDIC CROWN for 2025. The reported port of registry changed: København (2018–2021), then Copenhagen (2022–2023), then KØBENHAVN (2024–2025).
Its 39,555 t of CO₂ for 2025 is 32% above the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 411.7 kg CO₂, 12% below the type median of 467.6 kg. It logged 6,092 hours at sea against a median of 4,243 hours for its type that year. 3.4% 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 (49,669 t) and the lowest 2021 (26,501 t). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2018
Position 18 of 18 qualifying ro-pax ships by EEOI, at the 100th percentile. The dashed line is the type median, 335.9; this vessel reported 804.0.
Across the 5 ranked vessels operated by DFDS, the median percentile is 47. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 100,088,302 passenger-miles over 92,462 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 2.7% and CO₂ per nautical mile fell 2.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
