CRYSTAL SERENITY 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 68,870 gross tonnage it is smaller than 56% 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. Crystal Cruises is linked to 3 vessels on this register. The returns for 2019–2025 all give Nassau as port of registry.
Its 27,192 t of CO₂ for 2025 is 13% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 869.7 kg CO₂, close to the type median of 821.3 kg. It logged 2,465 hours at sea against a median of 3,133 hours for its type that year. 20.6% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 4 years with reported emissions, the highest was 2023 (45,380 t) and the lowest 2024 (5,440 t). Of the 8 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 32.8% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 399.8% and CO₂ per nautical mile rose 9.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
