BOCHEM NEW ORLEANS 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 Maderia as port of registry.
Its 1,965 t of CO₂ for 2025 is 64% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 247.8 kg CO₂, close to the type median of 250.2 kg. It logged 695 hours at sea against a median of 2,109 hours for its type that year. 17.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Its efficiency percentile within the type went from 6 in 2024 to 55 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 739 of 1,348 qualifying chemical tankers by EEOI, at the 55th percentile. The dashed line is the type median, 14.4; this vessel reported 15.4.
EEOI divides emissions by transport work, which for this vessel and year was 127,357,097 tonne-miles over 7,931 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.2% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 57.2% while distance sailed rose 8.0%and CO₂ per nautical mile rose 45.5%.That points mainly to how efficiently it sailed, rather than the other.
