MARAN GAS EFESSOS against its type
Built in 2014, it is the same age as the median LNG carrier on this register (build year 2014, 396 vessels with a known build year). At 103,928 gross tonnage it is smaller than 65% of the other 377 LNG carriers with a recorded tonnage. It is one of 41 LNG carriers here under the Greece flag, 7.6% of the 538 on the register. The same builder is recorded for 660 other vessels here, 109 of them LNG carriers. The returns for 2020–2025 all give Piraeus as port of registry.
Its 10,561 t of CO₂ for 2025 is 51% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 442.0 kg CO₂, 17% below the type median of 533.6 kg. It logged 1,569 hours at sea against a median of 2,940 hours for its type that year. 0.9% 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 (23,878 t) and the lowest 2022 (3,181 t). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 11.8% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 55.8% and CO₂ per nautical mile fell 27.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
