FAIRCHEM ALDEBARAN against its type

Built in 2017, it is 7 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,788 gross tonnage it is smaller than 73% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The returns for 2018–2025 all give Monrovia as port of registry.

Its 4,892 t of CO₂ for 2025 is 12% 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 229.4 kg CO₂, close to the type median of 250.2 kg. It logged 1,798 hours at sea against a median of 2,109 hours for its type that year. 9.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2021 (7,560 t) and the lowest 2023 (1,627 t). Its efficiency percentile within the type went from 55 in 2018 to 67 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 17.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 109.3% and CO₂ per nautical mile rose 28.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
