STOLT INVENTION against its type
Built in 1997, it is 13 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 24,634 gross tonnage it is larger than 57% 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 21 other vessels here, 6 of them chemical tankers. The returns for 2021–2025 all give Monrovia as port of registry.
Its 4,254 t of CO₂ for 2025 is 23% 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 402.5 kg CO₂, 1.6 times the type median of 250.2 kg. It logged 824 hours at sea against a median of 2,106 hours for its type that year. 9.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2024 (14,095 t) and the lowest 2022 (1,659 t). Its efficiency percentile within the type went from 54 in 2018 to 74 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 995 of 1,348 qualifying chemical tankers by EEOI, at the 74th percentile. The dashed line is the type median, 14.4; this vessel reported 22.5.
EEOI divides emissions by transport work, which for this vessel and year was 189,162,739 tonne-miles over 10,571 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 19.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 69.8% while distance sailed fell 68.2%and CO₂ per nautical mile fell 5.0%.That points mainly to how much the vessel sailed, rather than the other.
