COSCO SHIPPING LIBRA 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 194,864 gross tonnage it is larger than 96% 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 146 other vessels here, 43 of them container ships. The returns for 2018–2025 all give Hong Kong as port of registry.

Its 47,365 t of CO₂ for 2025 is 2.9 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 943.0 kg CO₂, 1.7 times the type median of 545.6 kg. It logged 3,424 hours at sea against a median of 3,155 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2024 (100,553 t) and the lowest 2018 (37,720 t). Its efficiency percentile within the type went from 2 in 2018 to 14 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 255 of 1,838 qualifying container ships by EEOI, at the 14th percentile. The dashed line is the type median, 14.2; this vessel reported 7.5.

EEOI divides emissions by transport work, which for this vessel and year was 6,323,827,770 tonne-miles over 50,231 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 25.6% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 52.9% while distance sailed fell 50.3%and CO₂ per nautical mile fell 5.2%.That points mainly to how much the vessel sailed, rather than the other.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 48,119 t
Methane (CH₄): 0.77 t
Nitrous oxide (N₂O): 2.76 t
Under EU ETS: 24,627 t, 52% of total
