CHALLENGE PINNACLE against its type
It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The returns for 2019–2025 all give Panama as port of registry.
Its 3,845 t of CO₂ for 2025 is 30% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 254.9 kg CO₂, close to the type median of 250.2 kg. It logged 1,362 hours at sea against a median of 2,106 hours for its type that year. 6.9% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2019 (5,008 t) and the lowest 2024 (263 t). Its efficiency percentile within the type went from 2 in 2019 to 3 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 47 of 1,348 qualifying chemical tankers by EEOI, at the 3rd percentile. The dashed line is the type median, 14.4; this vessel reported 6.8.
EEOI divides emissions by transport work, which for this vessel and year was 565,397,059 tonne-miles over 15,081 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 23.2% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 1,359.9% and CO₂ per nautical mile rose 16.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
