ALKYON against its type
Built in 2015, it is 8 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. The same builder is recorded for 160 other vessels here, 25 of them general cargo ships. Its MRV returns name it ALKYON for 2018 and SSI RELIANCE for 2019–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 2,076 t of CO₂ for 2025 is 26% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 192.9 kg CO₂, 1.6 times the type median of 122.2 kg. It logged 897 hours at sea against a median of 3,044 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2024 (6,164 t) and the lowest 2025 (2,076 t). Its efficiency percentile within the type went from 61 in 2019 to 56 in 2022 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 2,064 of 3,692 qualifying bulk carriers by EEOI, at the 56th percentile. The dashed line is the type median, 8.4; this vessel reported 8.9.
EEOI divides emissions by transport work, which for this vessel and year was 251,488,764 tonne-miles over 10,176 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 28.2% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 66.3% and CO₂ per nautical mile fell 9.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
