BUCCOO REEF against its type
Built in 2015, it is 5 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 21,101 gross tonnage it is smaller than 54% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 3 chemical tankers here under the Japan flag, 0.1% of the 2,344 on the register. The returns for 2018–2024 all give TOKYO as port of registry.
Its 11,828 t of CO₂ for 2025 is 2.1 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 203.5 kg CO₂, 19% below the type median of 250.2 kg. It logged 5,096 hours at sea against a median of 2,106 hours for its type that year. 6.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2020 (14,506 t) and the lowest 2018 (8,702 t). Its efficiency percentile within the type went from 58 in 2018 to 45 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 603 of 1,348 qualifying chemical tankers by EEOI, at the 45th percentile. The dashed line is the type median, 14.4; this vessel reported 13.4.
EEOI divides emissions by transport work, which for this vessel and year was 882,723,881 tonne-miles over 58,128 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.9% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 23.9% and CO₂ per nautical mile rose 1.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
