CSCL MERCURY against its type

Built in 2011, it is 3 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 150,853 gross tonnage it is larger than 91% 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 563 other vessels here, 243 of them container ships. The returns for 2018–2025 all give Hong Kong, China as port of registry.

Its 75,871 t of CO₂ for 2025 is 4.6 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 961.9 kg CO₂, 1.8 times the type median of 545.6 kg. It logged 5,322 hours at sea against a median of 3,155 hours for its type that year. 0.5% 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 (75,871 t) and the lowest 2021 (16,216 t). Its efficiency percentile within the type went from 22 in 2018 to 35 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 651 of 1,838 qualifying container ships by EEOI, at the 35th percentile. The dashed line is the type median, 14.2; this vessel reported 10.8.

EEOI divides emissions by transport work, which for this vessel and year was 6,999,203,874 tonne-miles over 78,879 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 42.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions rose 28.1% while distance sailed rose 29.3%and CO₂ per nautical mile fell 0.9%.That points mainly to how much the vessel sailed, rather than the other.
