BASTØ V against its type

Built in 2017, it is 17 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 7,870 gross tonnage it is smaller than 82% of the other 470 ro-pax ships with a recorded tonnage. It is one of 37 ro-pax ships here under the Norway flag, 7.5% of the 493 on the register. The same builder is recorded for 5 other vessels here, 2 of them ro-pax ships. Bastø Fosen is linked to 7 vessels on this register. The returns for 2021–2025 all give Horten as port of registry.

Its 2,972 t of CO₂ for 2025 is 90% below the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 112.2 kg CO₂, 76% below the type median of 467.6 kg. It logged 2,640 hours at sea against a median of 4,243 hours for its type that year. 16.4% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 5 years with reported emissions, the highest was 2021 (5,419 t) and the lowest 2023 (2,873 t). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year

Reported CO₂ in 2025 was 45.2% lower than in 2021, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 16.4% and CO₂ per nautical mile fell 9.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
