ARISTARCHOS against its type
It is one of 180 oil tankers here under the Bahamas flag, 5.1% of the 3,548 on the register. The returns for 2018–2025 all give Nassau as port of registry.
Its 8,149 t of CO₂ for 2024 is close to the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 308.6 kg CO₂, 24% below the type median of 408.2 kg. It logged 2,246 hours at sea against a median of 2,020 hours for its type that year. 4.9% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 6 years with reported emissions, the highest was 2021 (10,560 t) and the lowest 2018 (2,267 t). Its efficiency percentile within the type went from 48 in 2019 to 49 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 773 of 1,566 qualifying oil tankers by EEOI, at the 49th percentile. The dashed line is the type median, 7.6; this vessel reported 7.5.
EEOI divides emissions by transport work, which for this vessel and year was 1,080,803,714 tonne-miles over 26,410 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 259.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2024, emissions rose 7.9% while distance sailed rose 2.8%and CO₂ per nautical mile rose 4.9%.That points mainly to how efficiently it sailed, rather than the other.
