NAVIGATOR AURORA against its type
Built in 2016, it is 3 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 27,546 gross tonnage it is larger than 59% of the other 525 gas carriers with a recorded tonnage. It is one of 131 gas carriers here under the Liberia flag, 19.0% of the 688 on the register. The returns for 2020–2025 all give Monrovia as port of registry.
Its 27,785 t of CO₂ for 2025 is 4.7 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 298.9 kg CO₂, 17% above the type median of 256.2 kg. It logged 7,162 hours at sea against a median of 1,943 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2019 (32,770 t) and the lowest 2020 (21,145 t). Its efficiency percentile within the type went from 21 in 2018 to 55 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 161 of 292 qualifying gas carriers by EEOI, at the 55th percentile. The dashed line is the type median, 27.9; this vessel reported 32.2.
EEOI divides emissions by transport work, which for this vessel and year was 862,621,546 tonne-miles over 92,967 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.0% while distance sailed fell 0.6%and CO₂ per nautical mile fell 2.4%.That points mainly to how efficiently it sailed, rather than the other.
