STOLT ACER against its type
Built in 2004, it is 6 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 18,703 gross tonnage it is smaller 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 76 other vessels here, 58 of them chemical tankers. The returns for 2021–2024 all give MONROVIA as port of registry.
Its 8,403 t of CO₂ for 2024 is 44% above the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 275.8 kg CO₂, close to the type median of 253.5 kg. It logged 2,666 hours at sea against a median of 2,177 hours for its type that year. 8.2% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 4 years with reported emissions, the highest was 2024 (8,403 t) and the lowest 2021 (1,718 t). Its efficiency percentile within the type went from 57 in 2020 to 38 in 2024 (lower is more efficient). The one sister ship listed below with a 2024 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 454 of 1,194 qualifying chemical tankers by EEOI, at the 38th percentile. The dashed line is the type median, 15.9; this vessel reported 13.1.
EEOI divides emissions by transport work, which for this vessel and year was 639,974,867 tonne-miles over 30,471 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 10.1% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2022 to 2024, emissions rose 91.4% while distance sailed rose 138.7%and CO₂ per nautical mile fell 19.8%.That points mainly to how much the vessel sailed, rather than the other.
