HELLAS ATHINA against its type
It is one of 60 LNG carriers here under the Malta flag, 11.2% of the 538 on the register. The returns for 2021–2025 all give VALLETTA as port of registry.
Its 23,861 t of CO₂ for 2025 is 11% above the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 427.2 kg CO₂, 20% below the type median of 533.6 kg. It logged 3,827 hours at sea against a median of 2,940 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 5 years with reported emissions, the highest was 2024 (27,524 t) and the lowest 2021 (7,083 t). 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 type2021
Position 7 of 290 qualifying gas carriers by EEOI, at the 2nd percentile. The dashed line is the type median, 42.7; this vessel reported 10.2.
EEOI divides emissions by transport work, which for this vessel and year was 696,487,709 tonne-miles over 14,325 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 236.9% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 13.3% and CO₂ per nautical mile fell 16.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
