Its 30,800 t of CO₂ for 2025 is close to the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 714.3 kg CO₂, 13% below the type median of 821.3 kg. It logged 3,371 hours at sea against a median of 3,133 hours for its type that year. 14.6% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 3 years with reported emissions, the highest was 2025 (30,800 t) and the lowest 2023 (4,193 t). Of the 8 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Sources and how to read this

This page draws on 3 MRV reporting years, 5 of 5 vessel particulars, AIS movements in Norwegian waters and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, a name history, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
