AQUAMARINE STAR against its type
Built in 2019, it is 7 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 23,740 gross tonnage it is smaller than 80% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. Its MRV returns name it AQUAMARINE STAR for 2019 and MORNING ORCHID for 2021–2025. The returns for 2019–2025 all give PANAMA as port of registry.
Its 6,889 t of CO₂ for 2025 is 2.1 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 196.1 kg CO₂, 25% below the type median of 260.7 kg. It logged 3,202 hours at sea against a median of 1,200 hours for its type that year. 2.8% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2025 (6,889 t) and the lowest 2024 (985 t). Its efficiency percentile within the type went from 22 in 2019 to 53 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,710 of 3,241 qualifying bulk carriers by EEOI, at the 53rd percentile. The dashed line is the type median, 7.6; this vessel reported 7.8.
EEOI divides emissions by transport work, which for this vessel and year was 885,489,717 tonne-miles over 35,136 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 32.4% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 599.4% and CO₂ per nautical mile fell 0.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
