HAPPY KESTREL against its type
Built in 2013, it is the same age as the median gas carrier on this register (build year 2013, 530 vessels with a known build year). At 12,819 gross tonnage it is smaller than 74% 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 returns for 2019–2025 all give København as port of registry.
Its 10,833 t of CO₂ for 2025 is 1.8 times the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 226.6 kg CO₂, 12% below the type median of 256.2 kg. It logged 3,979 hours at sea against a median of 1,943 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 7 years with reported emissions, the highest was 2022 (11,212 t) and the lowest 2019 (4,734 t). Its efficiency percentile within the type went from 92 in 2019 to 84 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
