COSCO SHIPPING LEO 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 199,000 gross tonnage it is larger than 97% 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 reported port of registry changed: Hong Kong, China (2018–2022), then HONG KONG，CHINA (2023–2025).

Its 85,848 t of CO₂ for 2025 is 5.2 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 904.0 kg CO₂, 1.7 times the type median of 545.6 kg. It logged 5,815 hours at sea against a median of 3,155 hours for its type that year. 1.8% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2020 (101,682 t) and the lowest 2018 (60,845 t). Its efficiency percentile within the type went from 2 in 2018 to 10 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 190 of 1,838 qualifying container ships by EEOI, at the 10th percentile. The dashed line is the type median, 14.2; this vessel reported 7.0.

EEOI divides emissions by transport work, which for this vessel and year was 12,281,587,983 tonne-miles over 94,965 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 41.1% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 11.6% while distance sailed fell 9.5%and CO₂ per nautical mile fell 2.3%.That points mainly to how much the vessel sailed, rather than the other.
