KAVO ALKYON: CO₂ emissions 2018–2025

KAVO ALKYON against its type

Built in 2005, it is 7 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 38,845 gross tonnage it is larger than 59% 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 2018–2025 all give Majuro as port of registry.

Its 2,717 t of CO₂ for 2025 is 16% below the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 286.3 kg CO₂, close to the type median of 260.7 kg. It logged 1,227 hours at sea against a median of 1,199 hours for its type that year. 7.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2024 (3,132 t) and the lowest 2020 (986 t). Its efficiency percentile within the type went from 64 in 2019 to 18 in 2025 (lower is more efficient). The one comparable vessel listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025

Position 572 of 3,241 qualifying bulk carriers by EEOI, at the 18th percentile. The dashed line is the type median, 7.6; this vessel reported 5.4.

EEOI divides emissions by transport work, which for this vessel and year was 504,046,382 tonne-miles over 9,489 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 13.8% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 13.3% while distance sailed fell 4.9%and CO₂ per nautical mile fell 8.8%.That points mainly to how efficiently it sailed, rather than the other.
