LUNNI against its type
Built in 2018, it is 8 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 14,402 gross tonnage it is smaller than 63% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 5 chemical tankers here under the Finland flag, 0.2% of the 2,344 on the register. The same builder is recorded for 65 other vessels here, one of them a chemical tanker. Its MRV returns name it STEN ODIN for 2018–2019 and LUNNI for 2020–2025. The reported port of registry changed: Bergen (2018–2019), then HELSINKI (2020–2025).
Its 11,486 t of CO₂ for 2025 is 2.1 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 237.0 kg CO₂, close to the type median of 250.2 kg. It logged 4,531 hours at sea against a median of 2,109 hours for its type that year. 12.8% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2025 (11,486 t) and the lowest 2018 (3,996 t). Its efficiency percentile within the type went from 64 in 2018 to 63 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 853 of 1,348 qualifying chemical tankers by EEOI, at the 63rd percentile. The dashed line is the type median, 14.4; this vessel reported 18.0.
EEOI divides emissions by transport work, which for this vessel and year was 638,485,826 tonne-miles over 48,466 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 187.5% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 3.9% while distance sailed rose 5.9%and CO₂ per nautical mile fell 1.8%.That points mainly to how much the vessel sailed, rather than the other.
