CMA CGM MERMAID against its type

Built in 2024, it is 16 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 28,468 gross tonnage it is smaller than 65% of the other 3,000 container ships with a recorded tonnage. It is one of 336 container ships here under the Malta flag, 9.6% of the 3,495 on the register. The same builder is recorded for 983 other vessels here, 86 of them container ships. CMA CGM is linked to 40 vessels on this register. The returns for 2024–2025 all give Valletta as port of registry.

Its 14,414 t of CO₂ for 2025 is 12% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 268.2 kg CO₂, 51% below the type median of 545.6 kg. It logged 4,996 hours at sea against a median of 3,155 hours for its type that year. 15.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 60 in 2024 to 76 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,407 of 1,838 qualifying container ships by EEOI, at the 76th percentile. The dashed line is the type median, 14.2; this vessel reported 23.6.

Across the 39 ranked vessels operated by CMA CGM, the median percentile is 26. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 610,774,152 tonne-miles over 53,738 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 9.1% higher than in 2024, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 9.1% while distance sailed fell 1.2%and CO₂ per nautical mile rose 10.4%.That points mainly to how efficiently it sailed, rather than the other.
