ACHILLEAS against its type
It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The reported port of registry changed: Valletta (2019), then Chios (2020–2025).
Its 19,340 t of CO₂ for 2025 is 2.4 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 518.8 kg CO₂, 29% above the type median of 403.2 kg. It logged 4,267 hours at sea against a median of 2,030 hours for its type that year. 8.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2025 (19,340 t) and the lowest 2022 (2,764 t). Its efficiency percentile within the type went from 34 in 2019 to 33 in 2025 (lower is more efficient). Of the 2 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 481 of 1,448 qualifying oil tankers by EEOI, at the 33rd percentile. The dashed line is the type median, 7.5; this vessel reported 6.2.
EEOI divides emissions by transport work, which for this vessel and year was 3,099,282,051 tonne-miles over 37,276 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 286.2% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 39.2% while distance sailed rose 36.3%and CO₂ per nautical mile rose 2.2%.That points mainly to how much the vessel sailed, rather than the other.
