ZHONG YUAN HAI YUN KAI TUO against its type
Built in 2018, it is 11 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 40,250 gross tonnage it is larger than 99% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 38 general cargo ships here under the China flag, 1.2% of the 3,081 on the register. The returns for 2020–2025 all give Guangzhou as port of registry.
Its 1,843 t of CO₂ for 2025 is 35% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 270.5 kg CO₂, 2.2 times the type median of 122.2 kg. It logged 513 hours at sea against a median of 3,044 hours for its type that year. 0.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2021 (5,340 t) and the lowest 2022 (1,831 t). Its efficiency percentile within the type went from 55 in 2020 to 97 in 2023 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 320 of 331 qualifying general cargo ships by EEOI, at the 97th percentile. The dashed line is the type median, 21.1; this vessel reported 60.4.
EEOI divides emissions by transport work, which for this vessel and year was 59,313,173 tonne-miles over 14,034 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 3.4% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 39.1% and CO₂ per nautical mile rose 21.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
