MONA against its type
It is one of 27 chemical tankers here under the Saudi Arabia flag, 1.2% of the 2,344 on the register. The returns for 2023–2025 all give Dammam as port of registry.
Its 1,811 t of CO₂ for 2025 is 67% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 250.8 kg CO₂, close to the type median of 250.2 kg. It logged 638 hours at sea against a median of 2,109 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2023 (6,615 t) and the lowest 2025 (1,811 t). Its efficiency percentile within the type went from 8 in 2023 to 38 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
