DIAMOND GAS METROPOLIS against its type
It is one of 63 LNG carriers here under the Bahamas flag, 11.7% of the 538 on the register. The returns for 2022–2025 all give NASSAU as port of registry.
Its 9,834 t of CO₂ for 2025 is 54% below the median of 21,516 t among the 351 LNG carriers on this register that reported for 2025. Per nautical mile it emitted 535.5 kg CO₂, close to the type median of 533.6 kg. It logged 1,214 hours at sea against a median of 2,940 hours for its type that year. 2.1% 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 (28,914 t) and the lowest 2025 (9,834 t). Of the 7 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.
