MAERSK HERRERA against its type
Built in 2018, it is 10 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 153,744 gross tonnage it is larger than 93% 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 returns for 2018–2025 all give Singapore as port of registry.
Its 75,532 t of CO₂ for 2025 is 4.6 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 811.6 kg CO₂, 49% above the type median of 545.6 kg. It logged 5,609 hours at sea against a median of 3,155 hours for its type that year. 0.3% 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 (75,532 t) and the lowest 2023 (4,731 t). Its efficiency percentile within the type was 4 in both 2018 and 2025. Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 73 of 1,838 qualifying container ships by EEOI, at the 4th percentile. The dashed line is the type median, 14.2; this vessel reported 6.2.
EEOI divides emissions by transport work, which for this vessel and year was 12,241,875,203 tonne-miles over 93,063 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 258.7% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 58.8% while distance sailed rose 81.9%and CO₂ per nautical mile fell 12.7%.That points mainly to how much the vessel sailed, rather than the other.
