ALEXANDROS III 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). It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. Its MRV returns name it KOZNITZA for 2018–2019 and ALEXANDROS III for 2020–2025. The reported port of registry changed: Valletta (2018–2019), then Majuro (2020–2025).
Its 576 t of CO₂ for 2025 is 82% 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 260.4 kg CO₂, close to the type median of 260.7 kg. It logged 326 hours at sea against a median of 1,200 hours for its type that year. 14.7% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2018 (9,314 t) and the lowest 2025 (576 t). Its efficiency percentile within the type went from 0 in 2018 to 89 in 2024 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 93.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 82.1% and CO₂ per nautical mile rose 14.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
