WILSON NANJING against its type
Built in 2012, it is 5 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 6,118 gross tonnage it is smaller than 52% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 112 general cargo ships here under the Norway flag, 3.6% of the 3,081 on the register. The same builder is recorded for 34 other vessels here, 32 of them general cargo ships. Wilson Ship Management is linked to 120 vessels on this register. The reported port of registry changed: Valletta (2018–2020), then Bergen (2021–2025).
Its 6,153 t of CO₂ for 2025 is 2.2 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 138.2 kg CO₂, 13% above the type median of 122.2 kg. It logged 4,163 hours at sea against a median of 3,044 hours for its type that year. 4.8% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2019 (6,832 t) and the lowest 2022 (5,343 t). Of the 8 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 12.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 9.8% and CO₂ per nautical mile rose 2.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
