AURORA against its type
Built in 1991, it is 11 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 8,610 gross tonnage it is smaller than 88% of the other 269 ro-ro ships with a recorded tonnage. It is one of 21 ro-ro ships here under the Finland flag, 6.8% of the 311 on the register. The same builder is recorded for 20 other vessels here, 3 of them ro-ro ships. Seatrans (Norway) is linked to 6 vessels on this register. Its MRV returns name it SC AHTELA for 2018–2022 and AURORA for 2025. The reported port of registry changed: Valletta (2018–2022), then Mariehamn (2025).
Its 3,990 t of CO₂ for 2025 is 81% below the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 240.9 kg CO₂, 26% below the type median of 327.0 kg. It logged 2,273 hours at sea against a median of 4,872 hours for its type that year. 19.2% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 6 years with reported emissions, the highest was 2020 (11,387 t) and the lowest 2025 (3,990 t). Its efficiency percentile within the type went from 3 in 2018 to 28 in 2022 (lower is more efficient). The one comparable vessel listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 50.6% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 60.3% and CO₂ per nautical mile rose 42.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
