CERRO ALTO EXPLORER 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 6,408 t of CO₂ for 2025 is close to the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 230.1 kg CO₂, 10% below the type median of 256.2 kg. It logged 2,106 hours at sea against a median of 1,943 hours for its type that year. 1.9% 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 (6,408 t) and the lowest 2023 (2,261 t). Its efficiency percentile within the type went from 26 in 2023 to 47 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 137 of 292 qualifying gas carriers by EEOI, at the 47th percentile. The dashed line is the type median, 27.9; this vessel reported 25.9.
EEOI divides emissions by transport work, which for this vessel and year was 247,108,369 tonne-miles over 27,853 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 183.4% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 160.3% while distance sailed rose 165.8%and CO₂ per nautical mile fell 2.1%.That points mainly to how much the vessel sailed, rather than the other.
