ISABELLA against its type
It is one of 41 LNG carriers here under the Greece flag, 7.6% of the 538 on the register. The returns for 2022–2025 all give Piraeus as port of registry.
Its 37,767 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 501.7 kg CO₂, close to the type median of 533.6 kg. It logged 4,987 hours at sea against a median of 2,940 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 4 years with reported emissions, the highest was 2023 (59,452 t) and the lowest 2024 (27,154 t). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.
