LNG HARMONY against its type
It is one of 25 LNG carriers here under the Liberia flag, 4.6% of the 538 on the register. The returns for 2023–2025 all give Monrovia as port of registry.
Its 4,468 t of CO₂ for 2025 is 79% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 411.8 kg CO₂, 23% below the type median of 533.6 kg. It logged 656 hours at sea against a median of 2,940 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 3 years with reported emissions, the highest was 2024 (11,321 t) and the lowest 2025 (4,468 t). Of the 7 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
