CB BALTIC against its type
Built in 2020, it is 10 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). It is one of 71 chemical tankers here under the Portugal flag, 3.0% of the 2,344 on the register. The returns for 2020–2025 all give Madeira as port of registry.
Its 7,576 t of CO₂ for 2025 is 37% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 314.3 kg CO₂, 26% above the type median of 250.2 kg. It logged 2,384 hours at sea against a median of 2,106 hours for its type that year. 16.6% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2021 (12,872 t) and the lowest 2025 (7,576 t). Its efficiency percentile within the type went from 21 in 2020 to 45 in 2025 (lower is more efficient). Of the 3 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 613 of 1,348 qualifying chemical tankers by EEOI, at the 45th percentile. The dashed line is the type median, 14.4; this vessel reported 13.5.
EEOI divides emissions by transport work, which for this vessel and year was 560,364,645 tonne-miles over 24,103 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 23.1% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 34.8% while distance sailed fell 33.3%and CO₂ per nautical mile fell 2.2%.That points mainly to how much the vessel sailed, rather than the other.
