UNISTREAM against its type
Built in 2010, it is 3 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 381 general cargo ships here under the Antigua and Barbuda flag, 12.4% of the 3,081 on the register. The same builder is recorded for 52 other vessels here, 36 of them general cargo ships. The returns for 2018–2025 all give Saint John's as port of registry.
Its 4,241 t of CO₂ for 2025 is 1.5 times 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 129.7 kg CO₂, close to the type median of 122.2 kg. It logged 3,412 hours at sea against a median of 3,044 hours for its type that year. 3.0% 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 2018 (5,157 t) and the lowest 2023 (1,679 t). Of the 6 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 54 of 155 qualifying other ship typess by EEOI, at the 34th percentile. The dashed line is the type median, 38.0; this vessel reported 28.7.
EEOI divides emissions by transport work, which for this vessel and year was 63,567,294 tonne-miles over 12,825 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 17.8% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 132.6% and CO₂ per nautical mile fell 8.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
