AURORA BOTNIA against its type
Built in 2021, it is 21 years newer than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 24,300 gross tonnage it is larger than 52% of the other 470 ro-pax ships with a recorded tonnage. It is one of 18 ro-pax ships here under the Finland flag, 3.7% of the 493 on the register. The same builder is recorded for 2 other vessels here, all of them ro-pax ships. The returns for 2021–2025 all give Vaasa as port of registry.
Its 11,070 t of CO₂ for 2025 is 63% 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 182.2 kg CO₂, 61% below the type median of 467.6 kg. It logged 4,490 hours at sea against a median of 4,243 hours for its type that year. 7.4% 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 2022 (16,004 t) and the lowest 2021 (5,774 t). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 91.7% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 6.0% and CO₂ per nautical mile fell 4.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
