ASOPOS against its type

It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2018–2025 all give Monrovia as port of registry.

Its 5,302 t of CO₂ for 2025 is 33% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 384.9 kg CO₂, close to the type median of 403.2 kg. It logged 1,467 hours at sea against a median of 2,030 hours for its type that year. 5.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2018 (14,065 t) and the lowest 2020 (4,084 t). Its efficiency percentile within the type went from 45 in 2018 to 87 in 2025 (lower is more efficient). Of the 3 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 1,255 of 1,448 qualifying oil tankers by EEOI, at the 87th percentile. The dashed line is the type median, 7.5; this vessel reported 15.3.

Reported CO₂ in 2025 was 62.3% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.

From 2020 to 2025, emissions rose 29.8% while distance sailed rose 31.3%and CO₂ per nautical mile fell 1.1%.That points mainly to how much the vessel sailed, rather than the other.
