ALPHA LIBERTY 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 93,274 gross tonnage it is larger than 94% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 107 bulk carriers here under the Greece flag, 1.3% of the 8,138 on the register. The same builder is recorded for 761 other vessels here, 26 of them bulk carriers. The returns for 2022–2025 all give Piraeus as port of registry.
Its 9,950 t of CO₂ for 2025 is 3.1 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 518.6 kg CO₂, 2.0 times the type median of 260.7 kg. It logged 1,897 hours at sea against a median of 1,200 hours for its type that year. 1.6% 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 (9,950 t) and the lowest 2022 (5,087 t). Its efficiency percentile within the type went from 0 in 2022 to 7 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 214 of 3,241 qualifying bulk carriers by EEOI, at the 7th percentile. The dashed line is the type median, 7.6; this vessel reported 4.3.
EEOI divides emissions by transport work, which for this vessel and year was 2,330,210,773 tonne-miles over 19,187 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 95.6% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 74.2% while distance sailed rose 58.9%and CO₂ per nautical mile rose 9.6%.That points mainly to how much the vessel sailed, rather than the other.
