ONE HONOLULU 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 96,790 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 (2022–2023), then TOKYO (2024).

Its 16,950 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 604.2 kg CO₂, 11% above the type median of 545.6 kg. It logged 1,958 hours at sea against a median of 3,155 hours for its type that year. 1.4% 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 (47,087 t) and the lowest 2025 (16,950 t). Its efficiency percentile within the type went from 16 in 2022 to 33 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 605 of 1,838 qualifying container ships by EEOI, at the 33rd percentile. The dashed line is the type median, 14.2; this vessel reported 10.5.

EEOI divides emissions by transport work, which for this vessel and year was 1,620,479,924 tonne-miles over 28,054 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 28.8% lower than in 2022, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 64.0% and CO₂ per nautical mile fell 10.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Where the 2025 emissions occurred

Methane, nitrous oxide and EU ETS2025

Total CO₂ equivalent: 17,217 t
Methane (CH₄): 0.27 t
Nitrous oxide (N₂O): 0.98 t
Under EU ETS: 7,746 t, 46% of total

Laden voyages2025

CO₂ on laden voyages: 14,484 t, 85% of total
Fuel, laden: 4,642 t

The rest of the 2025 total was emitted on ballast legs or at berth.
