MED BLUE JAY against its type
It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The returns for 2021–2025 all give Valletta as port of registry.
Its 6,214 t of CO₂ for 2025 is 12% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 179.5 kg CO₂, 28% below the type median of 250.2 kg. It logged 4,706 hours at sea against a median of 2,106 hours for its type that year. 6.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2025 (6,214 t) and the lowest 2021 (3,299 t). Its efficiency percentile within the type went from 99 in 2022 to 97 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
