NAVIGATOR GUSTO against its type
Built in 2011, it is 2 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 16,823 gross tonnage it is smaller than 66% 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 same builder is recorded for 761 other vessels here, 100 of them gas carriers. The returns for 2018–2025 all give Monrovia as port of registry.
Its 13,033 t of CO₂ for 2025 is 2.2 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 214.5 kg CO₂, 16% below the type median of 256.2 kg. It logged 5,822 hours at sea against a median of 1,943 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2022 (19,433 t) and the lowest 2018 (3,865 t). Its efficiency percentile within the type went from 55 in 2018 to 48 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 142 of 292 qualifying gas carriers by EEOI, at the 48th percentile. The dashed line is the type median, 27.9; this vessel reported 27.2.
EEOI divides emissions by transport work, which for this vessel and year was 479,863,402 tonne-miles over 60,763 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 237.2% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 27.4% while distance sailed fell 31.1%and CO₂ per nautical mile rose 5.4%.That points mainly to how much the vessel sailed, rather than the other.
