MEDALTA ADVENTURER against its type
It is one of 48 chemical tankers here under the Cayman Islands flag, 2.0% of the 2,344 on the register. The returns for 2018–2024 all give GEORGE TOWN as port of registry.
Its 12,222 t of CO₂ for 2025 is 2.2 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 213.4 kg CO₂, 15% below the type median of 250.2 kg. It logged 5,478 hours at sea against a median of 2,106 hours for its type that year. 6.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 8 years with reported emissions, the highest was 2018 (19,055 t) and the lowest 2023 (10,270 t). Its efficiency percentile within the type went from 58 in 2018 to 54 in 2025 (lower is more efficient). Of the 5 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 722 of 1,348 qualifying chemical tankers by EEOI, at the 54th percentile. The dashed line is the type median, 14.4; this vessel reported 15.2.
EEOI divides emissions by transport work, which for this vessel and year was 804,640,553 tonne-miles over 57,283 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 5.0% and CO₂ per nautical mile fell 5.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
