ADAMASTOS against its type
It is one of 59 gas carriers here under the Malta flag, 8.6% of the 688 on the register. The reported port of registry changed: VALETTA (2021–2022), then Valletta (2023–2025).
Its 52,801 t of CO₂ for 2025 is 8.8 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 526.6 kg CO₂, 2.1 times the type median of 256.2 kg. It logged 6,872 hours at sea against a median of 1,943 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 5 years with reported emissions, the highest was 2023 (67,798 t) and the lowest 2021 (6,510 t). Its efficiency percentile within the type went from 8 in 2024 to 14 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 42 of 292 qualifying gas carriers by EEOI, at the 14th percentile. The dashed line is the type median, 27.9; this vessel reported 14.7.
EEOI divides emissions by transport work, which for this vessel and year was 3,594,341,048 tonne-miles over 100,262 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 711.1% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 17.0% while distance sailed fell 18.4%and CO₂ per nautical mile rose 1.6%.That points mainly to how much the vessel sailed, rather than the other.
