LENA RIVER against its type
Built in 2013, it is 1 year older than the median LNG carrier on this register, which was built in 2014 (396 vessels with a known build year). At 100,236 gross tonnage it is smaller than 77% of the other 377 LNG carriers with a recorded tonnage. It is one of 111 LNG carriers here under the Marshall Islands flag, 20.6% of the 538 on the register. The same builder is recorded for 761 other vessels here, 41 of them LNG carriers. The returns for 2018–2025 all give Majuro as port of registry.
Its 4,541 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 783.2 kg CO₂, 47% above the type median of 533.6 kg. It logged 385 hours at sea against a median of 2,940 hours for its type that year. 5.5% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 7 years with reported emissions, the highest was 2020 (53,436 t) and the lowest 2025 (4,541 t). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 91.3% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 90.9% and CO₂ per nautical mile rose 17.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
