AMBIENCE against its type
Built in 1991, it is 19 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 70,285 gross tonnage it is smaller than 53% of the other 177 cruise ships with a recorded tonnage. It is one of 67 cruise ships here under the Bahamas flag, 33.2% of the 202 on the register. The same builder is recorded for 132 other vessels here, 60 of them cruise ships. Ambassador Cruise Line is linked to 3 vessels on this register. The returns for 2022–2025 all give Nassau as port of registry.
Its 50,588 t of CO₂ for 2025 is 1.6 times the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 709.9 kg CO₂, 14% below the type median of 821.3 kg. It logged 5,444 hours at sea against a median of 3,133 hours for its type that year. 11.4% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 4 years with reported emissions, the highest was 2025 (50,588 t) and the lowest 2022 (28,222 t). Of the 2 sister ships 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 79.3% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 34.5% and CO₂ per nautical mile fell 0.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
