AEGEAN STAR 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 81,306 gross tonnage it is larger than 73% of the other 2,841 oil tankers with a recorded tonnage. It is one of 244 oil tankers here under the Panama flag, 6.9% of the 3,548 on the register. The same builder is recorded for 461 other vessels here, 179 of them oil tankers. Its MRV returns name it AEGEAN STAR for 2018, MARVIN STAR for 2019 and CONSTANTIOS for 2022–2023. The reported port of registry changed: Panama city (2018), then PANAMA (2019), then MONROVIA (2022–2023).
Its 10,152 t of CO₂ for 2023 is 36% above the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 675.7 kg CO₂, 1.7 times the type median of 408.5 kg. It logged 2,027 hours at sea against a median of 1,807 hours for its type that year. 11.6% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 4 years with reported emissions, the highest was 2018 (24,458 t) and the lowest 2022 (4,480 t). Its efficiency percentile within the type went from 62 in 2018 to 40 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 642 of 1,615 qualifying oil tankers by EEOI, at the 40th percentile. The dashed line is the type median, 8.0; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 1,448,165,478 tonne-miles over 15,023 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 58.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.
From 2022 to 2023, emissions rose 126.6% while distance sailed rose 87.3%and CO₂ per nautical mile rose 21.0%.That points mainly to how much the vessel sailed, rather than the other.
