MAERSK PUELO against its type
Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). 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. The returns for 2021–2025 all give PANAMA as port of registry.
Its 45,366 t of CO₂ for 2025 is 2.8 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 773.8 kg CO₂, 42% above the type median of 545.6 kg. It logged 4,027 hours at sea against a median of 3,155 hours for its type that year. 3.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 5 years with reported emissions, the highest was 2024 (48,100 t) and the lowest 2022 (29,076 t). Its efficiency percentile within the type went from 64 in 2021 to 70 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,287 of 1,838 qualifying container ships by EEOI, at the 70th percentile. The dashed line is the type median, 14.2; this vessel reported 20.5.
EEOI divides emissions by transport work, which for this vessel and year was 2,211,916,626 tonne-miles over 58,631 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 17.5% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 5.7% and CO₂ per nautical mile fell 7.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
