ANGEL STAR 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 28,844 gross tonnage it is smaller than 80% 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 114 other vessels here, 20 of them oil tankers. Its MRV returns name it OPAL EXPRESS for 2019 and ANGEL STAR for 2023–2025.
Its 2,940 t of CO₂ for 2025 is 63% 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 278.6 kg CO₂, 31% below the type median of 403.2 kg. It logged 878 hours at sea against a median of 2,030 hours for its type that year. 6.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2019 (2,973 t) and the lowest 2023 (1,589 t). Its efficiency percentile within the type went from 7 in 2019 to 60 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 868 of 1,448 qualifying oil tankers by EEOI, at the 60th percentile. The dashed line is the type median, 7.5; this vessel reported 8.2.
EEOI divides emissions by transport work, which for this vessel and year was 357,244,228 tonne-miles over 10,551 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 85.0% while distance sailed rose 91.4%and CO₂ per nautical mile fell 3.3%.That points mainly to how much the vessel sailed, rather than the other.
