SOPHIA K against its type
Built in 2011, it is 1 year older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 31,218 gross tonnage it is smaller than 69% 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. Its MRV returns name it SOPHIA K for 2021 and SUPRA DUKE for 2024–2025. The returns for 2021–2025 all give Monrovia as port of registry.
Its 1,731 t of CO₂ for 2025 is 47% below the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 321.6 kg CO₂, 23% above the type median of 260.7 kg. It logged 543 hours at sea against a median of 1,199 hours for its type that year. 2.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2024 (5,305 t) and the lowest 2025 (1,731 t). Its efficiency percentile within the type went from 22 in 2021 to 55 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,787 of 3,241 qualifying bulk carriers by EEOI, at the 55th percentile. The dashed line is the type median, 7.6; this vessel reported 8.0.
EEOI divides emissions by transport work, which for this vessel and year was 217,225,847 tonne-miles over 5,383 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 54.8% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 67.4% while distance sailed fell 63.6%and CO₂ per nautical mile fell 10.3%.That points mainly to how much the vessel sailed, rather than the other.
