ASTREA against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 7,366 gross tonnage it is smaller than 97% of the other 2,841 oil tankers with a recorded tonnage. It is one of 17 oil tankers here under the Sweden flag, 0.5% of the 3,548 on the register. The same builder is recorded for 7 other vessels here. The reported port of registry changed: Donso (2019–2022), then Donsö (2023–2025).
Its 5,689 t of CO₂ for 2025 is 28% 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 153.8 kg CO₂, 62% below the type median of 403.2 kg. It logged 3,810 hours at sea against a median of 2,030 hours for its type that year. 10.6% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2023 (7,515 t) and the lowest 2025 (5,689 t). Its efficiency percentile within the type went from 98 in 2019 to 97 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,410 of 1,448 qualifying oil tankers by EEOI, at the 97th percentile. The dashed line is the type median, 7.5; this vessel reported 29.8.
EEOI divides emissions by transport work, which for this vessel and year was 190,892,617 tonne-miles over 36,997 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 23.7% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 12.4% while distance sailed fell 17.4%and CO₂ per nautical mile rose 6.0%.That points mainly to how much the vessel sailed, rather than the other.
