ZHEN ZHU HAI against its type
Built in 2015, it is 3 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 24,748 gross tonnage it is smaller than 77% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 637 bulk carriers here under the Hong Kong flag, 7.8% of the 8,138 on the register. The returns for 2018–2025 all give Hong Kong as port of registry.
Its 405 t of CO₂ for 2025 is 87% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 176.5 kg CO₂, 32% below the type median of 260.7 kg. It logged 202 hours at sea against a median of 1,200 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2020 (7,880 t) and the lowest 2025 (405 t). Its efficiency percentile within the type went from 48 in 2018 to 69 in 2024 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 92.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 89.2% and CO₂ per nautical mile fell 30.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
