TIAN ZHEN against its type
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 2019–2025 all give Shanghai as port of registry.
Its 5,862 t of CO₂ for 2025 is 2.1 times 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 261.4 kg CO₂, 2.1 times the type median of 122.2 kg. It logged 1,831 hours at sea against a median of 3,044 hours for its type that year. 5.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2021 (12,596 t) and the lowest 2020 (5,112 t). Its efficiency percentile within the type went from 10 in 2019 to 33 in 2023 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 110 of 331 qualifying general cargo ships by EEOI, at the 33rd percentile. The dashed line is the type median, 21.1; this vessel reported 16.0.
EEOI divides emissions by transport work, which for this vessel and year was 544,794,632 tonne-miles over 38,836 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 27.8% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 42.3% and CO₂ per nautical mile rose 10.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
