STOLT ILEX against its type

Built in 2010, it is the same age as the median chemical tanker on this register (build year 2010, 1,951 vessels with a known build year). At 11,668 gross tonnage it is smaller than 75% 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 same builder is recorded for 52 other vessels here, 48 of them chemical tankers. The returns for 2023–2025 all give Monrovia as port of registry.

Its 1,346 t of CO₂ for 2025 is 76% 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 194.0 kg CO₂, 22% below the type median of 250.2 kg. It logged 631 hours at sea against a median of 2,109 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2018 (7,525 t) and the lowest 2020 (1,181 t). Its efficiency percentile within the type went from 50 in 2018 to 42 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 562 of 1,348 qualifying chemical tankers by EEOI, at the 42nd percentile. The dashed line is the type median, 14.4; this vessel reported 13.0.

EEOI divides emissions by transport work, which for this vessel and year was 103,859,568 tonne-miles over 6,938 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 82.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2024, so the series has gaps.

From 2023 to 2025, emissions fell 57.7% while distance sailed fell 58.3%and CO₂ per nautical mile rose 1.4%.That points mainly to how much the vessel sailed, rather than the other.
