MSC MARIANNA against its type
Built in 2002, it is 6 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 73,819 gross tonnage it is larger than 64% of the other 3,000 container ships with a recorded tonnage. It is one of 387 container ships here under the Panama flag, 11.1% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. Mediterranean Shipping Company SRL is linked to 105 vessels on this register. The returns for 2018–2025 all give Panama as port of registry.
Its 34,443 t of CO₂ for 2025 is 2.1 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 770.0 kg CO₂, 41% above the type median of 545.6 kg. It logged 3,091 hours at sea against a median of 3,155 hours for its type that year. 5.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2021 (52,034 t) and the lowest 2023 (3,906 t). Its efficiency percentile within the type went from 39 in 2018 to 51 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 934 of 1,838 qualifying container ships by EEOI, at the 51st percentile. The dashed line is the type median, 14.2; this vessel reported 14.4.
Across the 103 ranked vessels operated by Mediterranean Shipping Company SRL, the median percentile is 37. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 2,386,935,551 tonne-miles over 44,732 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 10.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, so the series has gaps.
From 2024 to 2025, emissions fell 11.7% while distance sailed fell 20.0%and CO₂ per nautical mile rose 10.4%.That points mainly to how much the vessel sailed, rather than the other.
