KING SEAWAYS against its type
Built in 1987, it is 13 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 31,360 gross tonnage it is larger than 72% 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 29 other vessels here, 15 of them ro-pax ships. The reported port of registry changed: København (2018–2021), then Kobenhavn (2022), then Copenhagen (2023–2025).
Its 43,917 t of CO₂ for 2025 is 46% 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 471.5 kg CO₂, close to the type median of 467.6 kg. It logged 5,802 hours at sea against a median of 4,243 hours for its type that year. 3.6% 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 2018 (50,671 t) and the lowest 2020 (34,773 t). Of the 4 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2018
Position 16 of 18 qualifying ro-pax ships by EEOI, at the 88th percentile. The dashed line is the type median, 335.9; this vessel reported 507.9.
EEOI divides emissions by transport work, which for this vessel and year was 85,802,879 passenger-miles over 94,712 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 13.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 8.3% and CO₂ per nautical mile rose 2.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
