MAERSK IDAHO against its type
Built in 2000, it is 8 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 50,698 gross tonnage it is larger than 52% of the other 3,000 container ships with a recorded tonnage. It is one of 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. The reported port of registry changed: Norfolk (2018–2020), then Singapore (2021–2025).
Its 23,356 t of CO₂ for 2025 is 43% 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 500.4 kg CO₂, close to the type median of 545.6 kg. It logged 3,469 hours at sea against a median of 3,155 hours for its type that year. 2.9% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (56,993 t) and the lowest 2022 (13,914 t). Its efficiency percentile within the type went from 47 in 2018 to 60 in 2025 (lower is more efficient). Of the 7 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 1,111 of 1,838 qualifying container ships by EEOI, at the 60th percentile. The dashed line is the type median, 14.2; this vessel reported 17.1.
EEOI divides emissions by transport work, which for this vessel and year was 1,366,671,738 tonne-miles over 46,674 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 59.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 38.9% while distance sailed fell 35.0%and CO₂ per nautical mile fell 5.9%.That points mainly to how much the vessel sailed, rather than the other.
