UNISTAR against its type
Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,351 gross tonnage it is larger than 50% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 3 general cargo ships here under the Canada flag, 0.1% of the 3,081 on the register. The reported port of registry changed: Saint John's (2018–2022), then St. John (2023–2025).
Its 2,896 t of CO₂ for 2025 is close to 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 113.6 kg CO₂, close to the type median of 122.2 kg. It logged 2,757 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 2023 (3,625 t) and the lowest 2022 (1,914 t). Of the 6 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 47 of 155 qualifying other ship typess by EEOI, at the 30th percentile. The dashed line is the type median, 38.0; this vessel reported 26.8.
EEOI divides emissions by transport work, which for this vessel and year was 108,600,075 tonne-miles over 23,089 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 16.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 0.4% and CO₂ per nautical mile fell 9.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
