SOLAR KAREN against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2021–2024 all give Monrovia as port of registry.
Its 2,163 t of CO₂ for 2024 is 63% below the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 227.7 kg CO₂, 10% below the type median of 253.5 kg. It logged 788 hours at sea against a median of 2,177 hours for its type that year. 8.7% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2022 (6,354 t) and the lowest 2021 (1,196 t). Its efficiency percentile within the type went from 0 in 2021 to 1 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 10 of 1,194 qualifying chemical tankers by EEOI, at the 1st percentile. The dashed line is the type median, 15.9; this vessel reported 6.2.
EEOI divides emissions by transport work, which for this vessel and year was 348,898,387 tonne-miles over 9,499 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 80.9% higher than in 2021, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 44.2% while distance sailed fell 36.2%and CO₂ per nautical mile fell 12.6%.That points mainly to how much the vessel sailed, rather than the other.
