MSC JENNY against its type

Built in 1995, it is 13 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 28,397 gross tonnage it is smaller than 65% 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. No other vessel on this register is recorded with the same builder. Its MRV returns name it MSC JENNY for 2018–2021 and MSC JENNY II for 2022–2025. The returns for 2018–2025 all give Madeira as port of registry.

Its 9,583 t of CO₂ for 2025 is 41% 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 345.0 kg CO₂, 37% below the type median of 545.6 kg. It logged 2,905 hours at sea against a median of 3,155 hours for its type that year. 7.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2019 (19,354 t) and the lowest 2022 (8,581 t). Its efficiency percentile within the type went from 70 in 2018 to 74 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,360 of 1,838 qualifying container ships by EEOI, at the 74th percentile. The dashed line is the type median, 14.2; this vessel reported 22.4.

EEOI divides emissions by transport work, which for this vessel and year was 427,815,625 tonne-miles over 27,780 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 34.0% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 20.5% while distance sailed fell 17.6%and CO₂ per nautical mile fell 3.6%.That points mainly to how much the vessel sailed, rather than the other.
