DA CAI YUN against its type
Built in 2012, it is 3 years newer than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 20,454 gross tonnage it is larger than 79% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 15 vessels in the other ship types category here under the Hong Kong flag, 3.0% of the 499 on the register. The returns for 2021–2025 all give Hong Kong as port of registry.
Its 1,913 t of CO₂ for 2024 is 70% below the median of 6,327 t among the 269 vessels in the other ship types category on this register that reported for 2024. Per nautical mile it emitted 233.5 kg CO₂, close to the type median of 226.4 kg. It logged 957 hours at sea against a median of 2,435 hours for its type that year. 3.7% of its 2024 emissions were at berth; the median for vessels in the other ship types category was 3.3%. Across 4 years with reported emissions, the highest was 2021 (5,425 t) and the lowest 2024 (1,913 t). Its efficiency percentile within the type went from 19 in 2021 to 1 in 2024 (lower is more efficient). Of the 3 comparable vessels listed below with a 2024 return, 1 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 3 of 155 qualifying other ship typess by EEOI, at the 1st percentile. The dashed line is the type median, 38.0; this vessel reported 11.5.
EEOI divides emissions by transport work, which for this vessel and year was 166,678,571 tonne-miles over 8,194 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 64.7% lower than in 2021, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 64.4% while distance sailed fell 64.0%and CO₂ per nautical mile fell 0.9%.That points mainly to how much the vessel sailed, rather than the other.
