ALLURE OF THE SEAS against its type

Built in 2010, it is the same age as the median cruise ship on this register (build year 2010, 195 vessels with a known build year). At 225,282 gross tonnage it is larger than 100% 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 7 other vessels here, one of them a cruise ship. Royal Caribbean International is linked to 25 vessels on this register. The returns for 2020–2025 all give Nassau as port of registry.

Its 100,989 t of CO₂ for 2025 is 3.2 times the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 1,841.7 kg CO₂, 2.2 times the type median of 821.3 kg. It logged 3,595 hours at sea against a median of 3,133 hours for its type that year. 19.6% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Of the 8 comparable vessels listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

2020: 6,191 t20206,1912025: 100,989 t2025100,989

Reported CO₂ in 2025 was 1,531.3% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.

From 2020 to 2025, emissions rose 1,531.3% and CO₂ per nautical mile rose 34.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 2 MRV reporting years, 5 of 5 vessel particulars and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, AIS movements in Norwegian waters, 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.
