ASUKA II against its type
Built in 1990, it is 16 years older than the median passenger ship on this register, which was built in 2006 (127 vessels with a known build year). At 50,142 gross tonnage it is larger than 53% of the other 117 passenger ships with a recorded tonnage. It is the only passenger ship on this register under the Japan flag. The same builder is recorded for 38 other vessels here. Crystal Cruises is linked to 3 vessels on this register. The returns for 2018–2024 all give YOKOHAMA as port of registry.
Its 9,405 t of CO₂ for 2025 is 33% above the median of 7,055 t among the 32 passenger ships on this register that reported for 2025. Per nautical mile it emitted 686.2 kg CO₂, 2.8 times the type median of 248.9 kg. It logged 876 hours at sea against a median of 2,827 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for passenger ships was 12.8%. Across 3 years with reported emissions, the highest was 2025 (9,405 t) and the lowest 2024 (5,166 t).

Reported CO₂ by year
Reported CO₂ in 2025 was 36.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 82.0% and CO₂ per nautical mile fell 3.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
