ALKYONIS 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 23,266 gross tonnage it is smaller than 82% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. The same builder is recorded for 323 other vessels here, 238 of them bulk carriers. The returns for 2022–2025 all give Monrovia as port of registry.

Its 4,506 t of CO₂ for 2025 is 39% 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 200.8 kg CO₂, 23% below the type median of 260.7 kg. It logged 2,662 hours at sea against a median of 1,200 hours for its type that year. 4.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2024 (5,409 t) and the lowest 2020 (755 t). Its efficiency percentile within the type went from 24 in 2018 to 41 in 2025 (lower is more efficient). Of the 5 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 1,326 of 3,241 qualifying bulk carriers by EEOI, at the 41st percentile. The dashed line is the type median, 7.6; this vessel reported 7.0.

0255075100more efficientless efficientThis vessel: 41st percentile, EEOI 7.0

EEOI divides emissions by transport work, which for this vessel and year was 643,784,286 tonne-miles over 22,445 nautical miles.

Reported CO₂ by year

2018: 1,986 t20181,9862019: 5,092 t20192020: 755 t20202022: 4,568 t20222023: 3,401 t20232024: 5,409 t20242025: 4,506 t20254,506

Reported CO₂ in 2025 was 126.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2024 to 2025, emissions fell 16.7% while distance sailed fell 14.2%and CO₂ per nautical mile fell 2.8%.That points mainly to how much the vessel sailed, rather than the other.
