TRANSPORTER 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 6,620 gross tonnage it is smaller than 94% 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 reported port of registry changed: Santa Cruz de Tenerife (2018), then Mariehamn (2020–2025).
Its 10,000 t of CO₂ for 2025 is 53% 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 148.8 kg CO₂, 54% below the type median of 327.0 kg. It logged 5,764 hours at sea against a median of 4,872 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 8 years with reported emissions, the highest was 2021 (12,845 t) and the lowest 2018 (2,896 t). Its efficiency percentile within the type went from 38 in 2019 to 27 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 53 of 192 qualifying ro-ro ships by EEOI, at the 27th percentile. The dashed line is the type median, 85.3; this vessel reported 64.4.
EEOI divides emissions by transport work, which for this vessel and year was 155,231,760 tonne-miles over 67,204 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 245.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 7.4% while distance sailed fell 1.8%and CO₂ per nautical mile fell 5.7%.That points mainly to how efficiently it sailed, rather than the other.
