CMB PARTNER against its type
It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. Its MRV returns name it CMB PARTNER for 2018 and ZEPHYROS for 2023–2025. The returns for 2018–2025 all give MAJURO as port of registry.
Its 4,261 t of CO₂ for 2025 is 32% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 275.2 kg CO₂, close to the type median of 260.7 kg. It logged 1,737 hours at sea against a median of 1,200 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2018 (6,126 t) and the lowest 2025 (4,261 t). Its efficiency percentile within the type went from 63 in 2018 to 36 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 1,187 of 3,241 qualifying bulk carriers by EEOI, at the 36th percentile. The dashed line is the type median, 7.6; this vessel reported 6.7.
EEOI divides emissions by transport work, which for this vessel and year was 634,959,762 tonne-miles over 15,479 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 30.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.
From 2023 to 2025, emissions fell 16.9% while distance sailed fell 19.2%and CO₂ per nautical mile rose 2.9%.That points mainly to how much the vessel sailed, rather than the other.
