MARIUS 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 28,433 gross tonnage it is smaller than 65% of the other 3,000 container ships with a recorded tonnage. It is one of 32 container ships here under the France flag, 0.9% of the 3,495 on the register. Its MRV returns name it NORDMAPLE for 2018–2020 and MARIUS for 2021–2025. The reported port of registry changed: Valletta (2019–2022), then Marseille (2023–2025).
Its 7,613 t of CO₂ for 2025 is 53% 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 351.6 kg CO₂, 36% below the type median of 545.6 kg. It logged 1,416 hours at sea against a median of 3,155 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2020 (10,409 t) and the lowest 2018 (5,633 t). Its efficiency percentile within the type went from 68 in 2018 to 83 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,522 of 1,838 qualifying container ships by EEOI, at the 83rd percentile. The dashed line is the type median, 14.2; this vessel reported 28.6.
EEOI divides emissions by transport work, which for this vessel and year was 266,550,070 tonne-miles over 21,653 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 35.1% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 22.8% while distance sailed fell 25.1%and CO₂ per nautical mile rose 3.0%.That points mainly to how much the vessel sailed, rather than the other.
