SOVEREIGN against its type
Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 42,331 gross tonnage it is smaller than 62% 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 196 other vessels here, 75 of them oil tankers. The returns for 2019–2025 all give MONROVIA as port of registry.
Its 4,036 t of CO₂ for 2025 is 49% 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 409.3 kg CO₂, close to the type median of 403.2 kg. It logged 1,721 hours at sea against a median of 2,030 hours for its type that year. 14.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Its efficiency percentile within the type went from 73 in 2019 to 85 in 2025 (lower is more efficient).

Efficiency against its own type2025
Position 1,225 of 1,448 qualifying oil tankers by EEOI, at the 85th percentile. The dashed line is the type median, 7.5; this vessel reported 14.1.
EEOI divides emissions by transport work, which for this vessel and year was 287,240,569 tonne-miles over 9,860 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 64.3% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2019 to 2025, emissions fell 64.3% while distance sailed fell 65.4%and CO₂ per nautical mile rose 3.4%.That points mainly to how much the vessel sailed, rather than the other.
