ONE FOREVER against its type
Built in 2024, it is 16 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 154,724 gross tonnage it is larger than 94% 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 21 other vessels here, 10 of them container ships. Ocean Network Express is linked to 30 vessels on this register. The reported port of registry changed: Hong Kong (2024), then Singapore (2025).
Its 41,553 t of CO₂ for 2025 is 2.5 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 675.2 kg CO₂, 24% above the type median of 545.6 kg. It logged 4,696 hours at sea against a median of 3,155 hours for its type that year. 2.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Its efficiency percentile within the type went from 6 in 2024 to 4 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 83 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.
Across the 30 ranked vessels operated by Ocean Network Express, the median percentile is 11. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 6,680,512,862 tonne-miles over 61,542 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 28.8% higher than in 2024, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 28.8% while distance sailed rose 36.3%and CO₂ per nautical mile fell 5.5%.That points mainly to how much the vessel sailed, rather than the other.
