K ONSET against its type

Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 8,450 gross tonnage it is smaller than 86% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2022–2025 all give Monrovia as port of registry.

Its 7,100 t of CO₂ for 2025 is 28% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 200.9 kg CO₂, 20% below the type median of 250.2 kg. It logged 3,905 hours at sea against a median of 2,109 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2025 (7,100 t) and the lowest 2023 (257 t). Its efficiency percentile within the type went from 82 in 2024 to 89 in 2025 (lower is more efficient). Of the 4 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 1,202 of 1,348 qualifying chemical tankers by EEOI, at the 89th percentile. The dashed line is the type median, 14.4; this vessel reported 36.2.

Reported CO₂ in 2025 was 180.6% higher than in 2022, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 20.7% while distance sailed rose 23.5%and CO₂ per nautical mile fell 2.3%.That points mainly to how much the vessel sailed, rather than the other.
