ASTOR against its type
Its 10,820 t of CO₂ for 2025 is 1.8 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 234.9 kg CO₂, close to the type median of 256.2 kg. It logged 3,316 hours at sea against a median of 1,943 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 3 years with reported emissions, the highest was 2025 (10,820 t) and the lowest 2023 (1,348 t). Its efficiency percentile within the type went from 4 in 2023 to 18 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 53 of 292 qualifying gas carriers by EEOI, at the 18th percentile. The dashed line is the type median, 27.9; this vessel reported 15.5.
EEOI divides emissions by transport work, which for this vessel and year was 696,708,306 tonne-miles over 46,064 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 702.6% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 58.8% while distance sailed rose 56.0%and CO₂ per nautical mile rose 1.8%.That points mainly to how much the vessel sailed, rather than the other.
