Its 57,762 t of CO₂ for 2025 is 1.8 times the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 1,319.8 kg CO₂, 1.6 times the type median of 821.3 kg. It logged 2,602 hours at sea against a median of 3,133 hours for its type that year. 6.3% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 8 years with reported emissions, the highest was 2018 (167,531 t) and the lowest 2021 (4,321 t). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.
