ONE FREEDOM against its type
Built in 2022, it is 14 years newer 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 362 container ships here under the Singapore flag, 10.4% of the 3,495 on the register. The same builder is recorded for 127 other vessels here, 46 of them container ships. The reported port of registry changed: Hong Kong (2022–2024), then Singapore (2025).
Its 48,078 t of CO₂ for 2025 is 2.9 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 777.0 kg CO₂, 42% above the type median of 545.6 kg. It logged 4,840 hours at sea against a median of 3,155 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2024 (58,196 t) and the lowest 2022 (7,457 t). Its efficiency percentile within the type went from 2 in 2022 to 19 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 360 of 1,838 qualifying container ships by EEOI, at the 19th percentile. The dashed line is the type median, 14.2; this vessel reported 8.2.
EEOI divides emissions by transport work, which for this vessel and year was 5,863,180,488 tonne-miles over 61,877 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 544.7% higher than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 17.4% while distance sailed fell 18.1%and CO₂ per nautical mile rose 0.9%.That points mainly to how much the vessel sailed, rather than the other.
