AEGEAN STAR against its type
It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The returns for 2019–2023 all give Majuro as port of registry.
Its 6,819 t of CO₂ for 2023 is 26% above the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 255.9 kg CO₂, close to the type median of 258.0 kg. It logged 2,244 hours at sea against a median of 1,919 hours for its type that year. 11.8% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 3 years with reported emissions, the highest was 2023 (6,819 t) and the lowest 2020 (2,029 t). Its efficiency percentile within the type went from 5 in 2019 to 3 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2023 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2023
Position 41 of 1,230 qualifying chemical tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 15.6; this vessel reported 7.3.
EEOI divides emissions by transport work, which for this vessel and year was 935,327,846 tonne-miles over 26,641 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 14.9% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2020 to 2023, emissions rose 236.0% while distance sailed rose 236.1%and CO₂ per nautical mile fell <0.1%.That points mainly to how much the vessel sailed, rather than the other.
