NORSTREAM against its type

Built in 1999, it is 3 years older than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 20,296 gross tonnage it is smaller than 56% 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 23 other vessels here, 3 of them ro-ro ships. The returns for 2018–2025 all give Helsingfors as port of registry.

Its 20,928 t of CO₂ for 2025 is close to the median of 21,362 t among the 238 ro-ro ships on this register that reported for 2025. Per nautical mile it emitted 350.7 kg CO₂, close to the type median of 327.0 kg. It logged 4,271 hours at sea against a median of 4,872 hours for its type that year. 5.0% 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 2018 (92,291 t) and the lowest 2025 (20,928 t). Its efficiency percentile within the type went from 45 in 2022 to 72 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 139 of 192 qualifying ro-ro ships by EEOI, at the 72nd percentile. The dashed line is the type median, 85.3; this vessel reported 129.3.

EEOI divides emissions by transport work, which for this vessel and year was 161,829,802 tonne-miles over 59,681 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 77.3% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 20.1% while distance sailed fell 18.6%and CO₂ per nautical mile fell 1.9%.That points mainly to how much the vessel sailed, rather than the other.
