VIKING MARS 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 47,842 gross tonnage it is smaller than 69% of the other 177 cruise ships with a recorded tonnage. It is one of 10 cruise ships here under the Norway flag, 5.0% of the 202 on the register. The same builder is recorded for 132 other vessels here, 60 of them cruise ships. The returns for 2022–2025 all give BERGEN as port of registry.
Its 15,020 t of CO₂ for 2025 is 52% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 586.6 kg CO₂, 29% below the type median of 821.3 kg. It logged 1,921 hours at sea against a median of 3,133 hours for its type that year. 19.6% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 4 years with reported emissions, the highest was 2024 (21,342 t) and the lowest 2023 (10,367 t). Of the 8 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
