STAR MARTHA against its type
Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 90,095 gross tonnage it is larger than 89% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The same builder is recorded for 98 other vessels here, 50 of them bulk carriers. The returns for 2018–2025 all give Majuro as port of registry.
Its 3,802 t of CO₂ for 2025 is 17% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 466.3 kg CO₂, 1.8 times the type median of 260.7 kg. It logged 749 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 6 years with reported emissions, the highest was 2024 (8,389 t) and the lowest 2023 (3,028 t). Its efficiency percentile within the type went from 44 in 2018 to 16 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 531 of 3,241 qualifying bulk carriers by EEOI, at the 16th percentile. The dashed line is the type median, 7.6; this vessel reported 5.3.
EEOI divides emissions by transport work, which for this vessel and year was 720,043,561 tonne-miles over 8,153 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2024 to 2025, emissions fell 54.7% while distance sailed fell 54.8%and CO₂ per nautical mile rose 0.3%.That points mainly to how much the vessel sailed, rather than the other.
