ECO MERLIN against its type
It is one of 70 gas carriers here under the Marshall Islands flag, 10.2% of the 688 on the register. The returns for 2023–2025 all give Majuro as port of registry.
Its 2,743 t of CO₂ for 2025 is 54% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 261.3 kg CO₂, close to the type median of 256.2 kg. It logged 785 hours at sea against a median of 1,943 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 3 years with reported emissions, the highest was 2024 (14,714 t) and the lowest 2025 (2,743 t). Its efficiency percentile within the type went from 23 in 2023 to 42 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 122 of 292 qualifying gas carriers by EEOI, at the 42nd percentile. The dashed line is the type median, 27.9; this vessel reported 23.5.
EEOI divides emissions by transport work, which for this vessel and year was 116,509,771 tonne-miles over 10,496 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 71.8% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 81.4% while distance sailed fell 83.3%and CO₂ per nautical mile rose 11.7%.That points mainly to how much the vessel sailed, rather than the other.
