GENCO MARY 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. The returns for 2023–2025 all give Majuro as port of registry.
Its 2,828 t of CO₂ for 2025 is 13% 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 243.6 kg CO₂, close to the type median of 260.7 kg. It logged 1,152 hours at sea against a median of 1,200 hours for its type that year. 5.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Its efficiency percentile within the type went from 15 in 2023 to 18 in 2025 (lower is more efficient). Of the 6 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 588 of 3,241 qualifying bulk carriers by EEOI, at the 18th percentile. The dashed line is the type median, 7.6; this vessel reported 5.4.
EEOI divides emissions by transport work, which for this vessel and year was 521,773,063 tonne-miles over 11,611 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 42.8% lower than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 42.8% while distance sailed fell 45.2%and CO₂ per nautical mile rose 4.3%.That points mainly to how much the vessel sailed, rather than the other.
