POLYDEFKIS against its type
Built in 2020, it is 8 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 44,060 gross tonnage it is larger than 76% of the other 6,571 bulk carriers with a recorded tonnage. 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 2021–2025 all give Monrovia as port of registry.
Its 8,270 t of CO₂ for 2025 is 2.6 times the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 298.4 kg CO₂, 14% above the type median of 260.7 kg. It logged 2,563 hours at sea against a median of 1,199 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2021 (10,624 t) and the lowest 2022 (4,458 t). Its efficiency percentile within the type went from 11 in 2021 to 68 in 2025 (lower is more efficient). Of the 7 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 2,221 of 3,241 qualifying bulk carriers by EEOI, at the 68th percentile. The dashed line is the type median, 7.6; this vessel reported 9.0.
EEOI divides emissions by transport work, which for this vessel and year was 922,010,033 tonne-miles over 27,719 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.1% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 22.0% while distance sailed fell 20.7%and CO₂ per nautical mile fell 1.6%.That points mainly to how much the vessel sailed, rather than the other.
