NAVIGATOR LIBRA against its type
Built in 2012, it is 1 year older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 18,321 gross tonnage it is smaller 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 same builder is recorded for 983 other vessels here, 64 of them gas carriers. The returns for 2020–2022 all give Monrovia as port of registry.
Its 5,101 t of CO₂ for 2022 is 23% below the median of 6,608 t among the 355 gas carriers on this register that reported for 2022. Per nautical mile it emitted 237.9 kg CO₂, 15% below the type median of 279.0 kg. It logged 3,018 hours at sea against a median of 1,992 hours for its type that year. 11.9% of its 2022 emissions were at berth; the median for gas carriers was 5.7%. Across 5 years with reported emissions, the highest was 2019 (11,669 t) and the lowest 2022 (5,101 t). Its efficiency percentile within the type went from 43 in 2018 to 62 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2022
Position 197 of 316 qualifying gas carriers by EEOI, at the 62nd percentile. The dashed line is the type median, 38.5; this vessel reported 49.6.
EEOI divides emissions by transport work, which for this vessel and year was 102,906,597 tonne-miles over 21,445 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 53.4% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 6.6% while distance sailed rose 7.7%and CO₂ per nautical mile fell 13.2%.That points mainly to how efficiently it sailed, rather than the other.
