CL CHARLOTTE BRONTE against its type
It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2024–2025 all give Monrovia as port of registry.
Its 11,174 t of CO₂ for 2025 is 2.0 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 302.7 kg CO₂, 21% above the type median of 250.2 kg. It logged 3,217 hours at sea against a median of 2,109 hours for its type that year. 10.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (11,174 t) and the lowest 2023 (3,944 t). Its efficiency percentile within the type went from 5 in 2023 to 18 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
