COSCO SHIPPING STAR against its type

Built in 2019, it is 11 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 2019–2025 all give Hong Kong as port of registry.

Its 93,318 t of CO₂ for 2025 is 5.7 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 999.4 kg CO₂, 1.8 times the type median of 545.6 kg. It logged 5,685 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 7 years with reported emissions, the highest was 2025 (93,318 t) and the lowest 2023 (32,748 t). Its efficiency percentile within the type went from 4 in 2019 to 12 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 222 of 1,838 qualifying container ships by EEOI, at the 12th percentile. The dashed line is the type median, 14.2; this vessel reported 7.2.

EEOI divides emissions by transport work, which for this vessel and year was 12,889,179,558 tonne-miles over 93,373 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 120.7% higher than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 26.6% while distance sailed rose 17.3%and CO₂ per nautical mile rose 7.9%.That points mainly to how much the vessel sailed, rather than the other.
