MAERSK KOWLOON against its type
Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 82,794 gross tonnage it is larger than 68% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. The returns for 2018–2021 all give Monrovia as port of registry.
Its 5,313 t of CO₂ for 2021 is 67% below the median of 16,246 t among the 1,825 container ships on this register that reported for 2021. Per nautical mile it emitted 953.8 kg CO₂, 1.7 times the type median of 562.2 kg. It logged 333 hours at sea against a median of 2,808 hours for its type that year. 12.4% of its 2021 emissions were at berth; the median for container ships was 3.9%. Across 4 years with reported emissions, the highest was 2019 (61,681 t) and the lowest 2021 (5,313 t). Its efficiency percentile within the type went from 43 in 2018 to 48 in 2020 (lower is more efficient). The one sister ship listed below with a 2021 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2021 was 90.5% lower than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 88.4% and CO₂ per nautical mile rose 9.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
