FLEX AURORA against its type
It is one of 111 LNG carriers here under the Marshall Islands flag, 20.6% of the 538 on the register. The returns for 2020–2025 all give Majuro as port of registry.
Its 38,365 t of CO₂ for 2025 is 1.8 times the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 491.0 kg CO₂, close to the type median of 533.6 kg. It logged 5,538 hours at sea against a median of 2,940 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 6 years with reported emissions, the highest was 2025 (38,365 t) and the lowest 2020 (6,104 t). Of the 7 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.
