ALASKA against its type
Built in 2006, it is 4 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 85,421 gross tonnage it is larger than 85% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The reported port of registry changed: Piraeus (2018–2019), then Majuro (2020–2025).
Its 42,441 t of CO₂ for 2025 is 5.4 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 522.2 kg CO₂, 30% above the type median of 403.2 kg. It logged 7,071 hours at sea against a median of 2,030 hours for its type that year. 6.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2025 (42,441 t) and the lowest 2022 (4,048 t). Its efficiency percentile within the type went from 21 in 2018 to 43 in 2025 (lower is more efficient).

Efficiency against its own type2025
Position 624 of 1,448 qualifying oil tankers by EEOI, at the 43rd percentile. The dashed line is the type median, 7.5; this vessel reported 6.9.
EEOI divides emissions by transport work, which for this vessel and year was 6,115,371,758 tonne-miles over 81,268 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 212.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 74.9% while distance sailed rose 82.7%and CO₂ per nautical mile fell 4.3%.That points mainly to how much the vessel sailed, rather than the other.
