AEGEAN MARATHON against its type
Built in 2016, it is 6 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,349 gross tonnage it is larger than 74% of the other 2,841 oil tankers with a recorded tonnage. It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The returns for 2018–2025 all give Piraeus as port of registry.
Its 17,516 t of CO₂ for 2025 is 2.2 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 399.8 kg CO₂, close to the type median of 403.2 kg. It logged 4,485 hours at sea against a median of 2,030 hours for its type that year. 6.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2024 (28,258 t) and the lowest 2020 (1,524 t). Its efficiency percentile within the type went from 11 in 2018 to 29 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 416 of 1,448 qualifying oil tankers by EEOI, at the 29th percentile. The dashed line is the type median, 7.5; this vessel reported 5.9.
EEOI divides emissions by transport work, which for this vessel and year was 2,983,988,075 tonne-miles over 43,810 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 133.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 38.0% while distance sailed fell 39.6%and CO₂ per nautical mile rose 2.6%.That points mainly to how much the vessel sailed, rather than the other.
