BOTNIA ENABLER against its type
It is one of 11 ro-ro ships here under the Sweden flag, 3.5% of the 311 on the register. The reported port of registry changed: Göteborg (2022), then Gothenburg (2023–2025).
Its 36,528 t of CO₂ for 2025 is 1.7 times the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 409.7 kg CO₂, 25% above the type median of 327.0 kg. It logged 5,839 hours at sea against a median of 4,872 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Across 4 years with reported emissions, the highest was 2025 (36,528 t) and the lowest 2022 (20,170 t). Its efficiency percentile within the type went from 6 in 2022 to 0 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2 of 192 qualifying ro-ro ships by EEOI, at the 0th percentile. The dashed line is the type median, 85.3; this vessel reported 29.7.
EEOI divides emissions by transport work, which for this vessel and year was 1,228,664,312 tonne-miles over 89,152 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 81.1% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 3.4% while distance sailed rose 0.2%and CO₂ per nautical mile rose 3.2%.That points mainly to how efficiently it sailed, rather than the other.
