BWEK MADAGASCAR 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 7,222 gross tonnage it is smaller than 89% of the other 525 gas carriers with a recorded tonnage. It is one of 106 gas carriers here under the Singapore flag, 15.4% of the 688 on the register. Its MRV returns name it LUBERSAC for 2018–2023 and BWEK MADAGASCAR for 2025. The reported port of registry changed: Hong Kong (2018–2023), then Singapore (2025).
Its 206 t of CO₂ for 2025 is 97% below the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 174.8 kg CO₂, 32% below the type median of 256.2 kg. It logged 145 hours at sea against a median of 1,943 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 4 years with reported emissions, the highest was 2019 (614 t) and the lowest 2025 (206 t). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 63.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 56.9% and CO₂ per nautical mile fell 7.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
