ROSTRUM SOLAR 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.
Its 5,165 t of CO₂ for 2025 is 1.6 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 202.8 kg CO₂, 22% below the type median of 260.7 kg. It logged 2,295 hours at sea against a median of 1,200 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Its efficiency percentile within the type went from 38 in 2024 to 54 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,770 of 3,241 qualifying bulk carriers by EEOI, at the 54th percentile. The dashed line is the type median, 7.6; this vessel reported 7.9.
EEOI divides emissions by transport work, which for this vessel and year was 652,190,657 tonne-miles over 25,470 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 18.0% lower than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 18.0% while distance sailed fell 18.5%and CO₂ per nautical mile rose 0.7%.That points mainly to how much the vessel sailed, rather than the other.
