At 5,205 gross tonnage it is smaller than 60% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 69 general cargo ships here under the Malta flag, 2.2% of the 3,081 on the register. The reported port of registry changed: Valetta (2018–2019), then Valletta (2020), then Valetta (2021).
Its 281 t of CO₂ for 2021 is 93% below the median of 4,268 t among the 1,316 general cargo ships on this register that reported for 2021. Per nautical mile it emitted 83.7 kg CO₂, 56% below the type median of 189.1 kg. It logged 468 hours at sea against a median of 2,017 hours for its type that year. 1.1% of its 2021 emissions were at berth; the median for general cargo ships was 3.9%. Across 3 years with reported emissions, the highest was 2019 (533 t) and the lowest 2020 (271 t). Of the 2 comparable vessels listed below with a 2021 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2021 was 47.3% lower than in 2019, for EU/EEA voyages only.
From 2020 to 2021, emissions rose 3.7% and CO₂ per nautical mile rose 3.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
