AMWAJ against its type
It is one of 27 chemical tankers here under the Saudi Arabia flag, 1.2% of the 2,344 on the register. The returns for 2023–2025 all give Dammam as port of registry.
Its 4,341 t of CO₂ for 2025 is 22% 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 283.7 kg CO₂, 13% above the type median of 250.2 kg. It logged 1,306 hours at sea against a median of 2,106 hours for its type that year. 9.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 2 in 2023 to 27 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 370 of 1,348 qualifying chemical tankers by EEOI, at the 27th percentile. The dashed line is the type median, 14.4; this vessel reported 10.6.
EEOI divides emissions by transport work, which for this vessel and year was 410,313,800 tonne-miles over 15,303 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 56.7% lower than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 56.7% while distance sailed fell 56.9%and CO₂ per nautical mile rose 0.4%.That points mainly to how much the vessel sailed, rather than the other.
