ZEKO Y against its type
Built in 1981, it is 26 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 5,934 gross tonnage it is smaller than 54% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 34 general cargo ships here under the Comoros flag, 1.1% of the 3,081 on the register. The reported port of registry changed: Zanzibar (2020–2024), then MORONI (2025).
Its 779 t of CO₂ for 2025 is 72% 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 147.9 kg CO₂, 21% above the type median of 122.2 kg. It logged 541 hours at sea against a median of 3,044 hours for its type that year. 18.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2024 (1,369 t) and the lowest 2020 (352 t). Its efficiency percentile within the type went from 56 in 2022 to 68 in 2023 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 121.6% higher than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 43.1% and CO₂ per nautical mile rose 14.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
