BW LIBRA against its type
Built in 2015, it is 2 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 47,342 gross tonnage it is larger than 78% of the other 525 gas carriers with a recorded tonnage. It is one of 24 gas carriers here under the Isle of Man flag, 3.5% of the 688 on the register. The same builder is recorded for 761 other vessels here, 100 of them gas carriers. The returns for 2018–2021 all give Douglas as port of registry.
Its 5,439 t of CO₂ for 2021 is close to the median of 5,641 t among the 329 gas carriers on this register that reported for 2021. Per nautical mile it emitted 338.2 kg CO₂, 27% above the type median of 265.7 kg. It logged 1,091 hours at sea against a median of 1,780 hours for its type that year. 5.4% of its 2021 emissions were at berth; the median for gas carriers was 4.9%. Its efficiency percentile within the type went from 0 in 2018 to 26 in 2021 (lower is more efficient).

Efficiency against its own type2021
Position 75 of 290 qualifying gas carriers by EEOI, at the 26th percentile. The dashed line is the type median, 42.7; this vessel reported 25.6.
EEOI divides emissions by transport work, which for this vessel and year was 212,280,640 tonne-miles over 16,079 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 112.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2018 to 2021, emissions rose 112.0% while distance sailed rose 168.7%and CO₂ per nautical mile fell 21.1%.That points mainly to how much the vessel sailed, rather than the other.
