BOTHNIABORG against its type

Built in 2004, it is 2 years newer than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 12,635 gross tonnage it is smaller than 72% of the other 269 ro-ro ships with a recorded tonnage. It is one of 9 ro-ro ships here under the Netherlands flag, 2.9% of the 311 on the register. The same builder is recorded for 52 other vessels here, one of them a ro-ro ship. The returns for 2018–2025 all give Delfzijl as port of registry.

Its 18,479 t of CO₂ for 2025 is 13% 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 249.2 kg CO₂, 24% below the type median of 327.0 kg. It logged 5,354 hours at sea against a median of 4,872 hours for its type that year. 3.2% 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 2018 (20,510 t) and the lowest 2023 (16,438 t). Its efficiency percentile within the type went from 6 in 2018 to 3 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025

Position 6 of 192 qualifying ro-ro ships by EEOI, at the 3rd percentile. The dashed line is the type median, 85.3; this vessel reported 32.8.

EEOI divides emissions by transport work, which for this vessel and year was 564,079,976 tonne-miles over 74,148 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 9.9% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 1.8% while distance sailed fell 3.3%and CO₂ per nautical mile rose 1.5%.That points mainly to how much the vessel sailed, rather than the other.
