BOCHEM ROTTERDAM 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 5,630 t of CO₂ for 2025 is close to the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 215.2 kg CO₂, 14% below the type median of 250.2 kg. It logged 2,084 hours at sea against a median of 2,109 hours for its type that year. 4.6% 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 30 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 407 of 1,348 qualifying chemical tankers by EEOI, at the 30th percentile. The dashed line is the type median, 14.4; this vessel reported 11.1.
EEOI divides emissions by transport work, which for this vessel and year was 507,654,644 tonne-miles over 26,161 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.3% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 7.3% while distance sailed rose 2.8%and CO₂ per nautical mile rose 4.4%.That points mainly to how efficiently it sailed, rather than the other.
