ACACIA against its type
Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,557 gross tonnage it is larger than 77% 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 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it PTI DANUBE for 2018–2022 and ACACIA for 2024–2025. The reported port of registry changed: Hong Kong (2018–2022), then Monrovia (2024–2025).
Its 4,112 t of CO₂ for 2025 is 26% 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 308.4 kg CO₂, 23% above the type median of 250.2 kg. It logged 1,224 hours at sea against a median of 2,109 hours for its type that year. 5.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2020 (7,847 t) and the lowest 2025 (4,112 t). Its efficiency percentile within the type went from 19 in 2018 to 39 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 531 of 1,348 qualifying chemical tankers by EEOI, at the 39th percentile. The dashed line is the type median, 14.4; this vessel reported 12.5.
EEOI divides emissions by transport work, which for this vessel and year was 327,881,180 tonne-miles over 13,333 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 8.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 14.0% while distance sailed fell 26.0%and CO₂ per nautical mile rose 16.3%.That points mainly to how much the vessel sailed, rather than the other.
