ARISTARCHOS against its type
Built in 2021, it is 8 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 116,581 gross tonnage it is larger than 99% of the other 525 gas carriers with a recorded tonnage. It is one of 10 gas carriers here under the Greece flag, 1.5% of the 688 on the register. The same builder is recorded for 761 other vessels here, 100 of them gas carriers. The reported port of registry changed: VALLETTA (2022), then Piraeus (2023–2025).
Its 16,417 t of CO₂ for 2025 is 2.7 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 466.4 kg CO₂, 1.8 times the type median of 256.2 kg. It logged 2,374 hours at sea against a median of 1,943 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 4 years with reported emissions, the highest was 2024 (17,099 t) and the lowest 2023 (9,945 t). Its efficiency percentile within the type went from 3 in 2023 to 9 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 28 of 292 qualifying gas carriers by EEOI, at the 9th percentile. The dashed line is the type median, 27.9; this vessel reported 13.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,227,872,102 tonne-miles over 35,202 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.3% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 4.0% while distance sailed rose 3.9%and CO₂ per nautical mile fell 7.6%.That points mainly to how efficiently it sailed, rather than the other.
