ARISTEA against its type
Built in 2018, it is 8 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 63,364 gross tonnage it is larger than 64% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The returns for 2018–2025 all give VALLETTA as port of registry.
Its 17,212 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 365.3 kg CO₂, close to the type median of 403.2 kg. It logged 4,217 hours at sea against a median of 2,030 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2024 (18,011 t) and the lowest 2019 (2,513 t). Its efficiency percentile within the type went from 42 in 2018 to 56 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 822 of 1,448 qualifying oil tankers by EEOI, at the 56th percentile. The dashed line is the type median, 7.5; this vessel reported 8.0.
EEOI divides emissions by transport work, which for this vessel and year was 2,165,076,730 tonne-miles over 47,122 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 105.9% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 4.4% while distance sailed fell 6.2%and CO₂ per nautical mile rose 1.9%.That points mainly to how much the vessel sailed, rather than the other.
