ISLA DE BIOKO against its type
Built in 2016, it is 6 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 30,480 gross tonnage it is larger than 96% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The returns for 2018–2024 all give PANAMA as port of registry.
Its 9,410 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 214.0 kg CO₂, 14% below the type median of 250.2 kg. It logged 4,088 hours at sea against a median of 2,106 hours for its type that year. 4.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2023 (22,533 t) and the lowest 2025 (9,410 t). Its efficiency percentile within the type went from 22 in 2018 to 32 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 427 of 1,348 qualifying chemical tankers by EEOI, at the 32nd percentile. The dashed line is the type median, 14.4; this vessel reported 11.4.
EEOI divides emissions by transport work, which for this vessel and year was 827,640,281 tonne-miles over 43,977 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 44.5% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 47.6% and CO₂ per nautical mile fell 5.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
