WU ZHU HAI against its type
Built in 2008, it is 4 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 40,896 gross tonnage it is larger than 64% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 137 bulk carriers here under the China flag, 1.7% of the 8,138 on the register. The same builder is recorded for 98 other vessels here, 49 of them bulk carriers. The returns for 2020–2025 all give Tianjin as port of registry.
Its 1,329 t of CO₂ for 2025 is 59% 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 298.7 kg CO₂, 15% above the type median of 260.7 kg. It logged 455 hours at sea against a median of 1,200 hours for its type that year. 3.8% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2020 (5,929 t) and the lowest 2022 (1,047 t). Its efficiency percentile within the type went from 17 in 2020 to 30 in 2021 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 77.6% lower than in 2020, for EU/EEA voyages only.
From 2022 to 2025, emissions rose 27.0% and CO₂ per nautical mile rose 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
