BRITISH ACHIEVER against its type
It is one of 7 LNG carriers here under the Isle of Man flag, 1.3% of the 538 on the register. The returns for 2023–2025 all give Douglas as port of registry.
Its 12,751 t of CO₂ for 2025 is 41% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 608.5 kg CO₂, 14% above the type median of 533.6 kg. It logged 1,168 hours at sea against a median of 2,940 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for LNG carriers was 2.0%. Across 4 years with reported emissions, the highest was 2022 (38,088 t) and the lowest 2023 (6,917 t). Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 57.0% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 84.3% and CO₂ per nautical mile fell 7.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
