MSC SHANNON against its type
Built in 1991, it is 17 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 37,071 gross tonnage it is smaller than 59% 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 9 other vessels here, 3 of them container ships. Its MRV returns name it MSC SHANNON for 2018–2022 and MSC SHANNON III for 2023–2025. The returns for 2018–2025 all give Panama as port of registry.
Its 21,599 t of CO₂ for 2025 is 32% 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 401.5 kg CO₂, 26% below the type median of 545.6 kg. It logged 4,246 hours at sea against a median of 3,155 hours for its type that year. 6.5% 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 (37,209 t) and the lowest 2023 (21,531 t). Its efficiency percentile within the type went from 65 in 2018 to 72 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,317 of 1,838 qualifying container ships by EEOI, at the 72nd percentile. The dashed line is the type median, 14.2; this vessel reported 21.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,010,717,829 tonne-miles over 53,793 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 39.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 26.5% while distance sailed fell 29.5%and CO₂ per nautical mile rose 4.2%.That points mainly to how much the vessel sailed, rather than the other.
