ROSTRUM 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 MRV returns name it ROSTRUM for 2021–2024 and SOHAR for 2025. The returns for 2021–2025 all give Monrovia as port of registry.
Its 8,397 t of CO₂ for 2025 is 2.6 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 295.0 kg CO₂, 13% above the type median of 260.7 kg. It logged 2,742 hours at sea against a median of 1,200 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2025 (8,397 t) and the lowest 2024 (1,279 t). Its efficiency percentile within the type went from 53 in 2021 to 45 in 2025 (lower is more efficient). Of the 5 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 1,464 of 3,241 qualifying bulk carriers by EEOI, at the 45th percentile. The dashed line is the type median, 7.6; this vessel reported 7.2.
EEOI divides emissions by transport work, which for this vessel and year was 1,159,843,923 tonne-miles over 28,468 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 205.5% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 556.5% while distance sailed rose 513.2%and CO₂ per nautical mile rose 7.1%.That points mainly to how much the vessel sailed, rather than the other.
