ASTERIX I against its type
It is one of 10 gas carriers here under the Greece flag, 1.5% of the 688 on the register. The returns for 2023–2025 all give Piraeus as port of registry.
Its 5,076 t of CO₂ for 2025 is 15% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 473.1 kg CO₂, 1.8 times the type median of 256.2 kg. It logged 897 hours at sea against a median of 1,943 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 3 years with reported emissions, the highest was 2023 (33,892 t) and the lowest 2025 (5,076 t). Its efficiency percentile within the type went from 6 in 2023 to 7 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 22 of 292 qualifying gas carriers by EEOI, at the 7th percentile. The dashed line is the type median, 27.9; this vessel reported 12.8.
EEOI divides emissions by transport work, which for this vessel and year was 395,926,677 tonne-miles over 10,728 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 85.0% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 43.9% while distance sailed fell 47.9%and CO₂ per nautical mile rose 7.7%.That points mainly to how much the vessel sailed, rather than the other.
