NORWEGIAN BLISS against its type

Built in 2018, it is 8 years newer than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 168,028 gross tonnage it is larger than 95% 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 15,482 t of CO₂ for 2025 is 50% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 1,484.4 kg CO₂, 1.8 times the type median of 821.3 kg. It logged 579 hours at sea against a median of 3,133 hours for its type that year. 12.3% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

2018: 3,940 t20183,9402025: 15,482 t202515,482

Reported CO₂ in 2025 was 293.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, 2024, so the series has gaps.

From 2018 to 2025, emissions rose 293.0% and CO₂ per nautical mile rose 36.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
