HAPPY AVOCET against its type
Built in 2017, it is 4 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 13,549 gross tonnage it is smaller than 73% of the other 525 gas carriers with a recorded tonnage. It is one of 17 gas carriers here under the Denmark flag, 2.5% of the 688 on the register. The same builder is recorded for 96 other vessels here, 7 of them gas carriers. The returns for 2018–2025 all give København as port of registry.
Its 8,271 t of CO₂ for 2022 is 25% above the median of 6,608 t among the 355 gas carriers on this register that reported for 2022. Per nautical mile it emitted 224.7 kg CO₂, 19% below the type median of 279.0 kg. It logged 4,979 hours at sea against a median of 1,992 hours for its type that year. 5.3% of its 2022 emissions were at berth; the median for gas carriers was 5.7%. Across 4 years with reported emissions, the highest was 2018 (14,454 t) and the lowest 2022 (8,271 t). Its efficiency percentile within the type went from 82 in 2018 to 79 in 2022 (lower is more efficient). The one comparable vessel listed below with a 2022 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 250 of 316 qualifying gas carriers by EEOI, at the 79th percentile. The dashed line is the type median, 38.5; this vessel reported 77.3.
EEOI divides emissions by transport work, which for this vessel and year was 106,930,188 tonne-miles over 36,808 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 42.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2020 to 2022, emissions fell 21.5% while distance sailed fell 19.9%and CO₂ per nautical mile fell 2.1%.That points mainly to how much the vessel sailed, rather than the other.
