HELLAS POSEIDON against its type
Built in 2015, it is 2 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 48,022 gross tonnage it is larger than 90% of the other 525 gas carriers with a recorded tonnage. It is one of 59 gas carriers here under the Malta flag, 8.6% of the 688 on the register. The same builder is recorded for 761 other vessels here, 100 of them gas carriers. The returns for 2019–2025 all give Valletta as port of registry.
Its 4,102 t of CO₂ for 2025 is 31% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 386.4 kg CO₂, 1.5 times the type median of 256.2 kg. It logged 700 hours at sea against a median of 1,943 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 7 years with reported emissions, the highest was 2022 (21,501 t) and the lowest 2024 (3,492 t). Its efficiency percentile within the type went from 42 in 2019 to 22 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.

Efficiency against its own type2025
Position 66 of 292 qualifying gas carriers by EEOI, at the 22nd percentile. The dashed line is the type median, 27.9; this vessel reported 16.6.
EEOI divides emissions by transport work, which for this vessel and year was 247,719,807 tonne-miles over 10,616 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 70.1% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 17.5% while distance sailed rose 12.8%and CO₂ per nautical mile rose 4.1%.That points mainly to how much the vessel sailed, rather than the other.
