OCEANUS AURORA against its type
It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register.
Its 28,891 t of CO₂ for 2025 is 4.8 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 330.4 kg CO₂, 29% above the type median of 256.2 kg. It logged 6,368 hours at sea against a median of 1,943 hours for its type that year. 2.1% 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 (29,258 t) and the lowest 2023 (20,392 t). Its efficiency percentile within the type went from 5 in 2023 to 9 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.
