ALKYONI: CO₂ emissions 2020–2024

ALKYONI against its type

Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). At 31,538 gross tonnage it is smaller than 67% 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 returns for 2020–2024 all give Majuro as port of registry.

Its 2,363 t of CO₂ for 2024 is 30% below the median of 3,377 t among the 3,676 bulk carriers on this register that reported for 2024. Per nautical mile it emitted 290.8 kg CO₂, 10% above the type median of 264.0 kg. It logged 887 hours at sea against a median of 1,238 hours for its type that year. 4.8% of its 2024 emissions were at berth; the median for bulk carriers was 2.9%. Across 3 years with reported emissions, the highest was 2020 (3,625 t) and the lowest 2022 (1,270 t). Its efficiency percentile within the type went from 35 in 2020 to 53 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 1,509 of 2,858 qualifying bulk carriers by EEOI, at the 53rd percentile. The dashed line is the type median, 7.9; this vessel reported 8.1.

EEOI divides emissions by transport work, which for this vessel and year was 292,056,860 tonne-miles over 8,126 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2024 was 34.8% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2023, so the series has gaps.

From 2022 to 2024, emissions rose 86.0% while distance sailed rose 93.8%and CO₂ per nautical mile fell 4.1%.That points mainly to how much the vessel sailed, rather than the other.
