EMMA MAERSK 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). At 170,793 gross tonnage it is larger than 94% of the other 3,000 container ships with a recorded tonnage. It is one of 119 container ships here under the Denmark flag, 3.4% of the 3,495 on the register. The same builder is recorded for 64 other vessels here, 53 of them container ships. Maersk A/S is linked to 15 vessels on this register. The returns for 2018–2025 all give Taarbaek as port of registry.
Its 95,176 t of CO₂ for 2025 is 5.8 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 1,024.8 kg CO₂, 1.9 times the type median of 545.6 kg. It logged 5,871 hours at sea against a median of 3,155 hours for its type that year. 0.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2025 (95,176 t) and the lowest 2022 (8,513 t). Its efficiency percentile within the type went from 7 in 2018 to 26 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 481 of 1,838 qualifying container ships by EEOI, at the 26th percentile. The dashed line is the type median, 14.2; this vessel reported 9.3.
Across the 15 ranked vessels operated by Maersk A/S, the median percentile is 36. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 10,256,060,345 tonne-miles over 92,871 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 141.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 5.3% while distance sailed rose 9.0%and CO₂ per nautical mile fell 3.4%.That points mainly to how much the vessel sailed, rather than the other.
