OCEAN BREEZE 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 reported port of registry changed: Monrovia (2018–2023), then Madeira (2024).
Its 5,540 t of CO₂ for 2024 is close to the median of 5,830 t among the 1,451 chemical tankers on this register that reported for 2024. Per nautical mile it emitted 326.7 kg CO₂, 29% above the type median of 253.5 kg. It logged 1,556 hours at sea against a median of 2,177 hours for its type that year. 5.5% of its 2024 emissions were at berth; the median for chemical tankers was 5.9%. Across 6 years with reported emissions, the highest was 2019 (11,681 t) and the lowest 2018 (2,395 t). Its efficiency percentile within the type went from 7 in 2018 to 22 in 2024 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2024
Position 270 of 1,194 qualifying chemical tankers by EEOI, at the 22nd percentile. The dashed line is the type median, 15.9; this vessel reported 10.3.
EEOI divides emissions by transport work, which for this vessel and year was 536,861,434 tonne-miles over 16,959 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 131.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2023 to 2024, emissions fell 18.7% while distance sailed fell 24.0%and CO₂ per nautical mile rose 7.1%.That points mainly to how much the vessel sailed, rather than the other.
