ZHONG REN 122 against its type
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 returns for 2024–2025 all give Shanghai as port of registry.
Its 17,937 t of CO₂ for 2025 is 3.5 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 538.3 kg CO₂, 2.3 times the type median of 231.1 kg. It logged 3,590 hours at sea against a median of 2,231 hours for its type that year. 16.6% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Its efficiency percentile within the type went from 66 in 2024 to 86 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 102 of 119 qualifying other ship typess by EEOI, at the 86th percentile. The dashed line is the type median, 69.3; this vessel reported 186.8.
EEOI divides emissions by transport work, which for this vessel and year was 96,037,533 tonne-miles over 33,322 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 10.2% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 10.2% while distance sailed fell 13.7%and CO₂ per nautical mile rose 27.8%.That points mainly to how efficiently it sailed, rather than the other.
