OWUSU MARU against its type
It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The returns for 2022–2023 all give PANAMA as port of registry.
Its 724 t of CO₂ for 2025 is 78% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 260.7 kg CO₂, close to the type median of 260.7 kg. It logged 258 hours at sea against a median of 1,200 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2022 (14,175 t) and the lowest 2025 (724 t). Its efficiency percentile within the type went from 24 in 2022 to 2 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 71 of 3,241 qualifying bulk carriers by EEOI, at the 2nd percentile. The dashed line is the type median, 7.6; this vessel reported 3.3.
EEOI divides emissions by transport work, which for this vessel and year was 218,159,639 tonne-miles over 2,778 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 94.9% lower than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 75.2% while distance sailed fell 76.0%and CO₂ per nautical mile rose 3.6%.That points mainly to how much the vessel sailed, rather than the other.
