INDEPENDENCE OF THE SEAS against its type

Built in 2008, it is 2 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 155,889 gross tonnage it is larger than 94% 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 23 other vessels here, one of them a cruise ship. Royal Caribbean International is linked to 25 vessels on this register. The returns for 2018–2025 all give Nassau as port of registry.

Its 64,365 t of CO₂ for 2025 is 2.1 times the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 1,221.5 kg CO₂, 49% above the type median of 821.3 kg. It logged 3,245 hours at sea against a median of 3,133 hours for its type that year. 7.7% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 4 years with reported emissions, the highest was 2019 (70,999 t) and the lowest 2023 (10,610 t). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 4.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2024, so the series has gaps.

From 2023 to 2025, emissions rose 506.6% and CO₂ per nautical mile fell 12.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
