CMA CGM MAGDALENA against its type
Built in 2016, it is 8 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 96,424 gross tonnage it is larger than 78% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 86 other vessels here, 35 of them container ships. Its MRV returns name it CMA CGM MAGDALENA for 2018–2020 and MSC BRITTANY for 2021–2025. The reported port of registry changed: malta valletta (2019–2020), then MADEIRA (2021–2025).
Its 38,849 t of CO₂ for 2025 is 2.4 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 836.7 kg CO₂, 1.5 times the type median of 545.6 kg. It logged 3,199 hours at sea against a median of 3,155 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2025 (38,849 t) and the lowest 2020 (8,352 t). Its efficiency percentile within the type went from 21 in 2018 to 46 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 841 of 1,838 qualifying container ships by EEOI, at the 46th percentile. The dashed line is the type median, 14.2; this vessel reported 13.2.
EEOI divides emissions by transport work, which for this vessel and year was 2,954,332,319 tonne-miles over 46,431 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 80.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 22.1% while distance sailed rose 18.4%and CO₂ per nautical mile rose 3.1%.That points mainly to how much the vessel sailed, rather than the other.
