AWH ALMA against its type
Built in 2009, it is 1 year older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,939 gross tonnage it is smaller than 70% 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. Its MRV returns name it CHEM ALYA for 2018–2023 and AWH ALMA for 2024–2025. The returns for 2018–2025 all give Monrovia as port of registry.
Its 4,492 t of CO₂ for 2025 is 19% 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 254.0 kg CO₂, close to the type median of 250.2 kg. It logged 1,785 hours at sea against a median of 2,109 hours for its type that year. 21.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2024 (8,934 t) and the lowest 2023 (846 t). Its efficiency percentile within the type went from 85 in 2021 to 88 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,179 of 1,348 qualifying chemical tankers by EEOI, at the 88th percentile. The dashed line is the type median, 14.4; this vessel reported 33.8.
EEOI divides emissions by transport work, which for this vessel and year was 133,057,464 tonne-miles over 17,687 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 33.5% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions fell 49.7% while distance sailed fell 55.0%and CO₂ per nautical mile rose 11.8%.That points mainly to how much the vessel sailed, rather than the other.
