OU MAY against its type
Its 4,281 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 427.9 kg CO₂, 1.6 times the type median of 260.7 kg. It logged 987 hours at sea against a median of 1,200 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2024 (7,135 t) and the lowest 2022 (1,574 t). Its efficiency percentile within the type went from 2 in 2020 to 12 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 401 of 3,241 qualifying bulk carriers by EEOI, at the 12th percentile. The dashed line is the type median, 7.6; this vessel reported 4.9.
EEOI divides emissions by transport work, which for this vessel and year was 868,320,487 tonne-miles over 10,004 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 157.5% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 40.0% while distance sailed fell 35.5%and CO₂ per nautical mile fell 7.0%.That points mainly to how much the vessel sailed, rather than the other.
