BWEK TAHITI against its type
Built in 2010, it is 3 years older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 7,267 gross tonnage it is smaller than 88% of the other 525 gas carriers with a recorded tonnage. It is one of 59 gas carriers here under the Malta flag, 8.6% of the 688 on the register. Its MRV returns name it ESHIPS DANA for 2018–2019, TRISTAR DANA for 2020–2024 and BWEK TAHITI for 2025. The reported port of registry changed: Gibraltar (2018–2019), then Valletta (2020–2025).
Its 7,929 t of CO₂ for 2025 is 33% above the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 170.3 kg CO₂, 34% below the type median of 256.2 kg. It logged 3,878 hours at sea against a median of 1,943 hours for its type that year. 9.8% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2019 (13,675 t) and the lowest 2025 (7,929 t). Its efficiency percentile within the type went from 84 in 2018 to 99 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 290 of 292 qualifying gas carriers by EEOI, at the 99th percentile. The dashed line is the type median, 27.9; this vessel reported 138.1.
EEOI divides emissions by transport work, which for this vessel and year was 57,427,826 tonne-miles over 46,570 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 26.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 4.0% while distance sailed rose 0.5%and CO₂ per nautical mile fell 4.5%.That points mainly to how efficiently it sailed, rather than the other.
