ONE HOUSTON against its type
Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 96,801 gross tonnage it is larger than 78% of the other 3,000 container ships with a recorded tonnage. It is one of 22 container ships here under the Japan flag, 0.6% of the 3,495 on the register. The same builder is recorded for 11 other vessels here, 7 of them container ships. The reported port of registry changed: PANAMA (2023–2024), then Tokyo (2025).
Its 34,520 t of CO₂ for 2025 is 2.1 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 650.1 kg CO₂, 19% above the type median of 545.6 kg. It logged 3,692 hours at sea against a median of 3,155 hours for its type that year. 0.7% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 3 years with reported emissions, the highest was 2025 (34,520 t) and the lowest 2023 (23,931 t). Its efficiency percentile within the type went from 24 in 2023 to 29 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 541 of 1,838 qualifying container ships by EEOI, at the 29th percentile. The dashed line is the type median, 14.2; this vessel reported 9.8.
EEOI divides emissions by transport work, which for this vessel and year was 3,515,235,234 tonne-miles over 53,099 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 44.2% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 5.4% and CO₂ per nautical mile fell 3.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
