NORWEGIAN STAR against its type
Built in 2001, it is 9 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 91,740 gross tonnage it is larger than 60% 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 65 other vessels here, 29 of them cruise ships. Norwegian Cruise Line is linked to 19 vessels on this register. The returns for 2018–2025 all give Nassau as port of registry.
Its 50,847 t of CO₂ for 2025 is 1.6 times the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 950.7 kg CO₂, 16% above the type median of 821.3 kg. It logged 3,487 hours at sea against a median of 3,133 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 6 years with reported emissions, the highest was 2019 (78,192 t) and the lowest 2024 (46,313 t). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 25.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2024 to 2025, emissions rose 9.8% and CO₂ per nautical mile fell 13.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
