COSCO SHIPPING SEINE against its type

Built in 2017, it is 9 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 94,623 gross tonnage it is larger than 76% 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. COSCO Shipping Lines is linked to 2 vessels on this register. The returns for 2018–2025 all give Hong Kong as port of registry.

Its 31,033 t of CO₂ for 2025 is 1.9 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 771.8 kg CO₂, 41% above the type median of 545.6 kg. It logged 2,729 hours at sea against a median of 3,155 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 6 years with reported emissions, the highest was 2025 (31,033 t) and the lowest 2022 (4,848 t). Its efficiency percentile within the type went from 26 in 2018 to 34 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 629 of 1,838 qualifying container ships by EEOI, at the 34th percentile. The dashed line is the type median, 14.2; this vessel reported 10.6.

EEOI divides emissions by transport work, which for this vessel and year was 2,916,681,391 tonne-miles over 40,210 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 484.0% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2022 to 2025, emissions rose 540.1% while distance sailed rose 534.9%and CO₂ per nautical mile rose 0.8%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2025 emissions occurred
