AIDAAURA against its type
Built in 2003, it is 7 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 42,289 gross tonnage it is smaller than 75% of the other 177 cruise ships with a recorded tonnage. It is one of 24 cruise ships here under the Bermuda flag, 11.9% of the 202 on the register. The same builder is recorded for 61 other vessels here, one of them a cruise ship. Celestyal is linked to 2 vessels on this register. Its MRV returns name it AIDAAURA for 2018–2022 and CELESTYAL DISCOVERY for 2023–2025. The reported port of registry changed: Genova (2018–2022), then Valletta (2023–2024), then Hamilton (2025).
Its 30,241 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 693.5 kg CO₂, 16% below the type median of 821.3 kg. It logged 3,292 hours at sea against a median of 3,133 hours for its type that year. 28.9% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 7 years with reported emissions, the highest was 2019 (32,060 t) and the lowest 2020 (13,715 t). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 12.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions rose 0.5% and CO₂ per nautical mile fell 6.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
