ULTRAMARINE against its type
It is one of 13 cruise ships here under the Marshall Islands flag, 6.4% of the 202 on the register. The returns for 2022–2025 all give Majuro as port of registry.
Its 794 t of CO₂ for 2025 is 97% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 216.8 kg CO₂, 74% below the type median of 821.3 kg. It logged 461 hours at sea against a median of 3,133 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 3 years with reported emissions, the highest was 2023 (2,061 t) and the lowest 2025 (794 t). Of the 8 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 3.4% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 61.5% and CO₂ per nautical mile fell 14.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
