AIDAMIRA against its type
Built in 1999, it is 11 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 48,200 gross tonnage it is smaller than 68% 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 51 other vessels here, 35 of them cruise ships. Ambassador Cruise Line is linked to 3 vessels on this register. Its MRV returns name it COSTA NEORIVIERA for 2018, AIDAMIRA for 2019–2020 and AMBITION for 2023–2025. The reported port of registry changed: Genova (2018–2020), then Nassau (2023–2025).
Its 37,706 t of CO₂ for 2025 is 21% above the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 653.5 kg CO₂, 20% below the type median of 821.3 kg. It logged 4,515 hours at sea against a median of 3,133 hours for its type that year. 10.2% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 6 years with reported emissions, the highest was 2023 (40,785 t) and the lowest 2020 (12,962 t). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 2.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 8.7% and CO₂ per nautical mile rose 8.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
