NORWEGIAN PRIMA against its type

Built in 2022, it is 12 years newer than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 143,535 gross tonnage it is larger than 86% 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 132 other vessels here, 60 of them cruise ships. Norwegian Cruise Line is linked to 19 vessels on this register. The returns for 2022–2025 all give NASSAU as port of registry.

Its 56,875 t of CO₂ for 2025 is 1.8 times the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 1,366.1 kg CO₂, 1.7 times the type median of 821.3 kg. It logged 2,611 hours at sea against a median of 3,133 hours for its type that year. 12.7% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 4 years with reported emissions, the highest was 2024 (71,411 t) and the lowest 2022 (16,848 t). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 237.6% higher than in 2022, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 20.4% and CO₂ per nautical mile fell 3.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
