CMA CGM GEMINI 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 135,000 gross tonnage it is larger than 85% 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 761 other vessels here, 355 of them container ships. The returns for 2018–2025 all give Valletta as port of registry.

Its 42,432 t of CO₂ for 2025 is 2.6 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 832.5 kg CO₂, 1.5 times the type median of 545.6 kg. It logged 3,616 hours at sea against a median of 3,155 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2024 (48,567 t) and the lowest 2021 (20,604 t). Its efficiency percentile within the type went from 16 in 2018 to 22 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 399 of 1,838 qualifying container ships by EEOI, at the 22nd percentile. The dashed line is the type median, 14.2; this vessel reported 8.5.

EEOI divides emissions by transport work, which for this vessel and year was 4,986,102,233 tonne-miles over 50,969 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 28.8% 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 fell 12.6% while distance sailed fell 12.9%and CO₂ per nautical mile rose 0.3%.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: 43,098 t
Methane (CH₄): 0.68 t
Nitrous oxide (N₂O): 2.44 t
