LIBERA against its type
Built in 2006, it is 4 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,373 gross tonnage it is larger than 59% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 218 chemical tankers here under the Malta flag, 9.3% of the 2,344 on the register. The returns for 2018–2025 all give Valletta as port of registry.
Its 9,204 t of CO₂ for 2025 is 1.7 times the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 274.9 kg CO₂, close to the type median of 250.2 kg. It logged 3,366 hours at sea against a median of 2,106 hours for its type that year. 11.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (11,559 t) and the lowest 2021 (5,826 t). Its efficiency percentile within the type went from 77 in 2018 to 64 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.
