GREEN K-MAX 4 against its type
It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The returns for 2020–2025 all give Monrovia as port of registry.
Its 4,864 t of CO₂ for 2025 is 1.5 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 309.7 kg CO₂, 19% above the type median of 260.7 kg. It logged 1,437 hours at sea against a median of 1,200 hours for its type that year. 9.8% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2024 (8,244 t) and the lowest 2025 (4,864 t). Its efficiency percentile within the type went from 69 in 2020 to 10 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 326 of 3,241 qualifying bulk carriers by EEOI, at the 10th percentile. The dashed line is the type median, 7.6; this vessel reported 4.8.
EEOI divides emissions by transport work, which for this vessel and year was 1,024,080,000 tonne-miles over 15,709 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 34.3% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 41.0% while distance sailed fell 37.1%and CO₂ per nautical mile fell 6.2%.That points mainly to how much the vessel sailed, rather than the other.
