SIRIUS 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 23,456 gross tonnage it is smaller than 81% 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 180 other vessels here, 74 of them bulk carriers. The returns for 2020–2025 all give Majuro as port of registry.
Its 777 t of CO₂ for 2025 is 76% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 296.1 kg CO₂, 14% above the type median of 260.7 kg. It logged 289 hours at sea against a median of 1,200 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2019 (10,107 t) and the lowest 2025 (777 t). Its efficiency percentile within the type went from 92 in 2018 to 87 in 2024 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 60.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 72.6% and CO₂ per nautical mile rose 30.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
