BOCHEM CASABLANCA against its type
It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The returns for 2024–2025 all give MADEIRA as port of registry.
Its 5,838 t of CO₂ for 2025 is close to the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 206.2 kg CO₂, 18% below the type median of 250.2 kg. It logged 2,393 hours at sea against a median of 2,106 hours for its type that year. 4.3% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 18 in 2024 to 42 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 569 of 1,348 qualifying chemical tankers by EEOI, at the 42nd percentile. The dashed line is the type median, 14.4; this vessel reported 13.0.
EEOI divides emissions by transport work, which for this vessel and year was 448,694,082 tonne-miles over 28,317 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 55.8% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 55.8% while distance sailed rose 56.9%and CO₂ per nautical mile fell 0.7%.That points mainly to how much the vessel sailed, rather than the other.
