HANNAH KRISTINA 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 5,932 gross tonnage it is smaller than 96% of the other 269 ro-ro ships with a recorded tonnage. It is one of 6 ro-ro ships here under the Norway flag, 1.9% of the 311 on the register. The returns for 2024–2025 all give Bergen as port of registry.

Its 8,496 t of CO₂ for 2025 is 60% 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 168.4 kg CO₂, 49% below the type median of 327.0 kg. It logged 4,026 hours at sea against a median of 4,872 hours for its type that year. 13.6% of its 2025 emissions were at berth; the median for ro-ro ships was 4.3%. Its efficiency percentile within the type went from 72 in 2024 to 70 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 135 of 192 qualifying ro-ro ships by EEOI, at the 70th percentile. The dashed line is the type median, 85.3; this vessel reported 123.1.

EEOI divides emissions by transport work, which for this vessel and year was 69,005,117 tonne-miles over 50,454 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 10.1% higher than in 2024, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 10.1% while distance sailed rose 10.5%and CO₂ per nautical mile fell 0.4%.That points mainly to how much the vessel sailed, rather than the other.
