ONE CYGNUS against its type
Built in 2019, it is 11 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 145,647 gross tonnage it is larger than 89% 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 121 other vessels here, 22 of them container ships. The returns for 2019–2023 all give TOKYO as port of registry.
Its 3,904 t of CO₂ for 2023 is 73% below the median of 14,627 t among the 1,920 container ships on this register that reported for 2023. Per nautical mile it emitted 504.5 kg CO₂, close to the type median of 509.2 kg. It logged 584 hours at sea against a median of 2,716 hours for its type that year. 4.3% of its 2023 emissions were at berth; the median for container ships was 4.0%. Across 5 years with reported emissions, the highest was 2019 (31,203 t) and the lowest 2023 (3,904 t). Its efficiency percentile within the type went from 9 in 2019 to 0 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 4 of 1,664 qualifying container ships by EEOI, at the 0th percentile. The dashed line is the type median, 17.4; this vessel reported 4.3.
EEOI divides emissions by transport work, which for this vessel and year was 916,542,254 tonne-miles over 7,739 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 87.5% lower than in 2019, for EU/EEA voyages only.
From 2022 to 2023, emissions fell 64.3% while distance sailed fell 49.6%and CO₂ per nautical mile fell 29.2%.That points mainly to how much the vessel sailed, rather than the other.
