YANG A against its type
Built in 2009, it is the same age as the median vessel in the other ship types category on this register (build year 2009, 451 vessels with a known build year). At 10,055 gross tonnage it is larger than 51% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 52 vessels in the other ship types category here under the Portugal flag, 10.4% of the 499 on the register. The returns for 2021–2025 all give MADEIRA as port of registry.
Its 230 t of CO₂ for 2025 is 96% below the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 282.1 kg CO₂, 22% above the type median of 231.1 kg. It logged 87 hours at sea against a median of 2,231 hours for its type that year. 15.8% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 5 years with reported emissions, the highest was 2024 (5,974 t) and the lowest 2025 (230 t). Its efficiency percentile within the type went from 82 in 2021 to 38 in 2024 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 88.4% lower than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 96.2% and CO₂ per nautical mile rose 24.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
