DA ZI YUN 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). At 20,949 gross tonnage it is larger than 81% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 73 general cargo ships here under the Hong Kong flag, 2.4% of the 3,081 on the register. The returns for 2019–2025 all give Hong Kong as port of registry.
Its 305 t of CO₂ for 2023 is 92% below the median of 3,650 t among the 1,342 general cargo ships on this register that reported for 2023. Per nautical mile it emitted 218.0 kg CO₂, 13% above the type median of 193.7 kg. It logged 111 hours at sea against a median of 1,942 hours for its type that year. 19.3% of its 2023 emissions were at berth; the median for general cargo ships was 4.5%. Across 4 years with reported emissions, the highest was 2019 (5,619 t) and the lowest 2020 (191 t). Its efficiency percentile within the type went from 17 in 2019 to 24 in 2022 (lower is more efficient). Of the 2 comparable vessels listed below with a 2023 return, 0 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2024, 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Reported CO₂ by year
Reported CO₂ in 2023 was 94.6% lower than in 2019, for EU/EEA voyages only.
From 2022 to 2023, emissions fell 92.2% and CO₂ per nautical mile rose 0.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
