ZHI YUAN KOU 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 32,793 gross tonnage it is larger than 87% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 32 vessels in the other ship types category here under the China flag, 6.4% of the 499 on the register. The reported port of registry changed: Guangzhou (2018–2019), then YANG PU (2020–2025).
Its 12,120 t of CO₂ for 2025 is 2.4 times 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 523.4 kg CO₂, 2.3 times the type median of 231.1 kg. It logged 2,424 hours at sea against a median of 2,231 hours for its type that year. 16.5% 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 2019 (24,040 t) and the lowest 2024 (4,610 t). Its efficiency percentile within the type went from 75 in 2018 to 80 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 96 of 119 qualifying other ship typess by EEOI, at the 80th percentile. The dashed line is the type median, 69.3; this vessel reported 151.9.
EEOI divides emissions by transport work, which for this vessel and year was 79,790,191 tonne-miles over 23,155 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 160.4% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 162.9% while distance sailed rose 145.1%and CO₂ per nautical mile rose 7.3%.That points mainly to how much the vessel sailed, rather than the other.
