ALPHA OPTIMISM against its type
Built in 2016, it is 4 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 92,531 gross tonnage it is larger than 92% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 479 bulk carriers here under the Malta flag, 5.9% of the 8,138 on the register. The same builder is recorded for 461 other vessels here, 43 of them bulk carriers. The returns for 2023–2025 all give VALLETTA as port of registry.
Its 8,685 t of CO₂ for 2025 is 2.7 times the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 467.2 kg CO₂, 1.8 times the type median of 260.7 kg. It logged 1,915 hours at sea against a median of 1,199 hours for its type that year. 2.2% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Its efficiency percentile within the type went from 0 in 2023 to 2 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 73 of 3,241 qualifying bulk carriers by EEOI, at the 2nd percentile. The dashed line is the type median, 7.6; this vessel reported 3.3.
EEOI divides emissions by transport work, which for this vessel and year was 2,600,302,395 tonne-miles over 18,589 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 8.6% lower than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 8.6% while distance sailed fell 28.5%and CO₂ per nautical mile rose 27.9%.
