AQUARIUS against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,068 gross tonnage it is larger than 92% 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 returns for 2023–2025 all give MONROVIA as port of registry.
Its 5,870 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 265.0 kg CO₂, close to the type median of 250.2 kg. It logged 2,188 hours at sea against a median of 2,109 hours for its type that year. 4.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2023 (8,656 t) and the lowest 2025 (5,870 t). Its efficiency percentile within the type went from 47 in 2023 to 6 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 79 of 1,348 qualifying chemical tankers by EEOI, at the 6th percentile. The dashed line is the type median, 14.4; this vessel reported 7.4.
EEOI divides emissions by transport work, which for this vessel and year was 795,425,474 tonne-miles over 22,149 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 32.2% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 20.2% while distance sailed rose 5.9%and CO₂ per nautical mile fell 24.6%.That points mainly to how efficiently it sailed, rather than the other.
