MSC ARIANE: CO₂ emissions 2018–2025

MSC ARIANE against its type

Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 154,503 gross tonnage it is larger than 94% 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 660 other vessels here, 231 of them container ships. Mediterranean Shipping Company SRL is linked to 105 vessels on this register. The returns for 2019–2025 all give Panama as port of registry.

Its 24,227 t of CO₂ for 2025 is 48% above the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 974.3 kg CO₂, 1.8 times the type median of 545.6 kg. It logged 1,635 hours at sea against a median of 3,155 hours for its type that year. 2.0% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2019 (28,136 t) and the lowest 2021 (2,743 t). Its efficiency percentile within the type went from 18 in 2018 to 16 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 295 of 1,838 qualifying container ships by EEOI, at the 16th percentile. The dashed line is the type median, 14.2; this vessel reported 7.7.

Across the 103 ranked vessels operated by Mediterranean Shipping Company SRL, the median percentile is 37. This vessel is more efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 3,146,384,416 tonne-miles over 24,866 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 29.1% 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 8.5% while distance sailed rose 1.1%and CO₂ per nautical mile fell 9.6%.That points mainly to how efficiently it sailed, rather than the other.
