HOURAI MARU against its type
Built in 2019, it is 6 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 25,458 gross tonnage it is larger than 56% of the other 525 gas carriers with a recorded tonnage. It is one of 70 gas carriers here under the Marshall Islands flag, 10.2% of the 688 on the register. The returns for 2019–2025 all give MAJURO as port of registry.
Its 12,840 t of CO₂ for 2025 is 2.1 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 268.2 kg CO₂, close to the type median of 256.2 kg. It logged 3,018 hours at sea against a median of 1,943 hours for its type that year. 9.5% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 7 years with reported emissions, the highest was 2019 (17,876 t) and the lowest 2024 (11,581 t). Its efficiency percentile within the type went from 17 in 2019 to 43 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 127 of 292 qualifying gas carriers by EEOI, at the 43rd percentile. The dashed line is the type median, 27.9; this vessel reported 24.2.
EEOI divides emissions by transport work, which for this vessel and year was 531,223,418 tonne-miles over 47,874 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 28.2% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 10.9% and CO₂ per nautical mile fell 8.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
