BASTØ I against its type

Built in 1997, it is 3 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 5,505 gross tonnage it is smaller than 93% 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 20 other vessels here, 11 of them ro-pax ships. Bastø Fosen is linked to 7 vessels on this register. The returns for 2021–2025 all give Moss as port of registry.

Its 2,390 t of CO₂ for 2025 is 92% 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 159.8 kg CO₂, 66% below the type median of 467.6 kg. It logged 1,504 hours at sea against a median of 4,243 hours for its type that year. 17.9% 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 (3,408 t) and the lowest 2023 (1,679 t). Of the 5 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 29.9% lower than in 2021, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 9.1% and CO₂ per nautical mile rose 4.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
