ARDAS I against its type
It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The returns for 2023–2025 all give Monrovia as port of registry.
Its 10,188 t of CO₂ for 2025 is 29% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 390.0 kg CO₂, close to the type median of 403.2 kg. It logged 2,177 hours at sea against a median of 2,030 hours for its type that year. 9.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2024 (11,318 t) and the lowest 2023 (7,398 t). Its efficiency percentile within the type went from 20 in 2023 to 57 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.
