KARINA THERESA against its type

Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 5,706 gross tonnage it is smaller than 95% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 93 chemical tankers here under the Denmark flag, 4.0% of the 2,344 on the register. The returns for 2018–2025 all give Herning as port of registry.

Its 4,724 t of CO₂ for 2025 is 15% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 141.1 kg CO₂, 44% below the type median of 250.2 kg. It logged 3,475 hours at sea against a median of 2,109 hours for its type that year. 8.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (6,818 t) and the lowest 2025 (4,724 t). Its efficiency percentile within the type went from 99 in 2018 to 96 in 2025 (lower is more efficient). Of the 7 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 1,298 of 1,348 qualifying chemical tankers by EEOI, at the 96th percentile. The dashed line is the type median, 14.4; this vessel reported 46.8.

EEOI divides emissions by transport work, which for this vessel and year was 100,996,151 tonne-miles over 33,479 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 12.4% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 9.1% while distance sailed fell 2.7%and CO₂ per nautical mile fell 6.6%.That points mainly to how efficiently it sailed, rather than the other.
