ONE BLUE JAY against its type
Built in 2016, it is 8 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 155,000 gross tonnage it is larger than 94% 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. Its MRV returns name it NYK BLUE JAY for 2018 and ONE BLUE JAY for 2019–2022. The reported port of registry changed: PANAMA (2018), then TOKYO (2019–2022).
Its 6,576 t of CO₂ for 2022 is 57% below the median of 15,388 t among the 1,858 container ships on this register that reported for 2022. Per nautical mile it emitted 854.1 kg CO₂, 1.6 times the type median of 539.7 kg. It logged 591 hours at sea against a median of 2,699 hours for its type that year. 4.5% of its 2022 emissions were at berth; the median for container ships was 4.2%. Across 5 years with reported emissions, the highest was 2018 (35,991 t) and the lowest 2022 (6,576 t). Its efficiency percentile within the type went from 7 in 2018 to 10 in 2022 (lower is more efficient). Of the 3 sister ships listed below with a 2022 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 167 of 1,589 qualifying container ships by EEOI, at the 10th percentile. The dashed line is the type median, 16.9; this vessel reported 7.3.
EEOI divides emissions by transport work, which for this vessel and year was 900,771,233 tonne-miles over 7,699 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 81.7% lower than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 58.4% while distance sailed fell 63.1%and CO₂ per nautical mile rose 12.9%.That points mainly to how much the vessel sailed, rather than the other.
