LADY MARIS against its type
Built in 2001, it is 11 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 25,388 gross tonnage it is smaller 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 same builder is recorded for 468 other vessels here, 362 of them bulk carriers. Its MRV returns name it MASTRO MITROS for 2019–2024 and LADY MARIS for 2025. The returns for 2019–2025 all give Monrovia as port of registry.
Its 5,837 t of CO₂ for 2025 is 1.8 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 292.8 kg CO₂, 12% above the type median of 260.7 kg. It logged 3,255 hours at sea against a median of 1,200 hours for its type that year. 1.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2025 (5,837 t) and the lowest 2022 (319 t). Its efficiency percentile within the type went from 86 in 2019 to 64 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,084 of 3,241 qualifying bulk carriers by EEOI, at the 64th percentile. The dashed line is the type median, 7.6; this vessel reported 8.6.
EEOI divides emissions by transport work, which for this vessel and year was 675,570,602 tonne-miles over 19,932 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 304.6% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 618.1% and CO₂ per nautical mile fell 22.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
