COSCO JAPAN against its type

Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 91,051 gross tonnage it is larger than 71% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. China Ocean Shipping Co., Ltd. is linked to 3 vessels on this register. The reported port of registry changed: Hong Kong (2018–2024), then Singapore (2025).

Its 25,361 t of CO₂ for 2025 is 1.6 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 646.7 kg CO₂, 19% above the type median of 545.6 kg. It logged 2,910 hours at sea against a median of 3,155 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2024 (34,823 t) and the lowest 2018 (8,255 t). Its efficiency percentile within the type went from 38 in 2018 to 33 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 602 of 1,838 qualifying container ships by EEOI, at the 33rd percentile. The dashed line is the type median, 14.2; this vessel reported 10.4.

Across the 3 ranked vessels operated by China Ocean Shipping Co., Ltd., the median percentile is 23. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 2,433,903,071 tonne-miles over 39,218 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 207.2% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.

From 2024 to 2025, emissions fell 27.2% while distance sailed fell 12.2%and CO₂ per nautical mile fell 17.1%.
