ALDEBARAN against its type
Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,372 gross tonnage it is larger than 58% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 563 other vessels here, 217 of them oil tankers. Its MRV returns name it AURVIKEN for 2020–2022 and ALDEBARAN for 2024. The returns for 2020–2024 all give Monrovia as port of registry.
Its 4,563 t of CO₂ for 2024 is 44% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 422.9 kg CO₂, close to the type median of 408.2 kg. It logged 1,356 hours at sea against a median of 2,020 hours for its type that year. 5.8% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 4 years with reported emissions, the highest was 2021 (15,717 t) and the lowest 2024 (4,563 t). Its efficiency percentile within the type went from 22 in 2020 to 63 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 983 of 1,566 qualifying oil tankers by EEOI, at the 63rd percentile. The dashed line is the type median, 7.6; this vessel reported 8.7.
EEOI divides emissions by transport work, which for this vessel and year was 527,465,896 tonne-miles over 10,788 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 53.9% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2022 to 2024, emissions fell 67.9% while distance sailed fell 64.2%and CO₂ per nautical mile fell 10.2%.That points mainly to how much the vessel sailed, rather than the other.
