AEGEAN UNITY 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 14,314 t of CO₂ for 2025 is 1.8 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 451.2 kg CO₂, 12% above the type median of 403.2 kg. It logged 4,023 hours at sea against a median of 2,030 hours for its type that year. 8.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2023 (28,583 t) and the lowest 2020 (1,723 t). Its efficiency percentile within the type went from 17 in 2018 to 13 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 1.9% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 28.5% while distance sailed fell 35.6%and CO₂ per nautical mile rose 11.1%.That points mainly to how much the vessel sailed, rather than the other.
