COSCO SHIPPING NEBULA against its type

Built in 2018, it is 10 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 215,553 gross tonnage it is larger than 98% of the other 3,000 container ships with a recorded tonnage. It is one of 202 container ships here under the Hong Kong flag, 5.8% of the 3,495 on the register. The same builder is recorded for 194 other vessels here, 10 of them container ships. The returns for 2018–2025 all give Hong Kong as port of registry.

Its 83,970 t of CO₂ for 2025 is 5.1 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 982.7 kg CO₂, 1.8 times the type median of 545.6 kg. It logged 5,462 hours at sea against a median of 3,155 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2019 (102,236 t) and the lowest 2018 (21,136 t). Its efficiency percentile within the type went from 3 in 2018 to 23 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.
