DEE4 ILEX 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 2022–2025 all give MONROVIA as port of registry.
Its 4,402 t of CO₂ for 2025 is 20% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 216.0 kg CO₂, 14% below the type median of 250.2 kg. It logged 1,669 hours at sea against a median of 2,106 hours for its type that year. 4.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2024 (7,245 t) and the lowest 2023 (3,028 t). Its efficiency percentile within the type went from 40 in 2022 to 8 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 103 of 1,348 qualifying chemical tankers by EEOI, at the 8th percentile. The dashed line is the type median, 14.4; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 576,900,393 tonne-miles over 20,382 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 18.8% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 39.2% while distance sailed fell 33.6%and CO₂ per nautical mile fell 8.5%.That points mainly to how much the vessel sailed, rather than the other.
