AUSTRALIAN BULKER against its type
Built in 2017, it is 5 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 22,426 gross tonnage it is smaller than 85% 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 95 other vessels here, 64 of them bulk carriers. Its MRV returns name it AUSTRALIAN BULKER for 2021 and SEASTAR AVALON for 2024–2025. The reported port of registry changed: SINGAPORE (2021), then Majuro (2024–2025).
Its 3,598 t of CO₂ for 2025 is 11% 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 196.4 kg CO₂, 25% below the type median of 260.7 kg. It logged 1,662 hours at sea against a median of 1,200 hours for its type that year. 3.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2025 (3,598 t) and the lowest 2024 (412 t). Its efficiency percentile within the type went from 56 in 2021 to 62 in 2025 (lower is more efficient). Of the 2 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 2,019 of 3,241 qualifying bulk carriers by EEOI, at the 62nd percentile. The dashed line is the type median, 7.6; this vessel reported 8.5.
EEOI divides emissions by transport work, which for this vessel and year was 425,257,683 tonne-miles over 18,319 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 23.5% higher 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 rose 774.1% and CO₂ per nautical mile rose 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
