NYK WREN against its type
Built in 2018, it is 10 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 150,000 gross tonnage it is larger than 90% 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. Ocean Network Express is linked to 30 vessels on this register. Its MRV returns name it NYK WREN for 2018–2020 and ONE WREN for 2021. The returns for 2018–2021 all give TOKYO as port of registry.
Its 6,517 t of CO₂ for 2021 is 60% below the median of 16,246 t among the 1,825 container ships on this register that reported for 2021. Per nautical mile it emitted 754.2 kg CO₂, 34% above the type median of 562.2 kg. It logged 768 hours at sea against a median of 2,808 hours for its type that year. 1.6% of its 2021 emissions were at berth; the median for container ships was 3.9%. Across 4 years with reported emissions, the highest was 2019 (34,316 t) and the lowest 2021 (6,517 t). Its efficiency percentile within the type went from 3 in 2018 to 6 in 2021 (lower is more efficient). The one sister ship listed below with a 2021 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2021
Position 100 of 1,557 qualifying container ships by EEOI, at the 6th percentile. The dashed line is the type median, 16.2; this vessel reported 6.5.
Across the 30 ranked vessels operated by Ocean Network Express, the median percentile is 11. This vessel is more efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 1,007,312,210 tonne-miles over 8,641 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2021 was 48.0% lower than in 2018, for EU/EEA voyages only.
From 2020 to 2021, emissions fell 80.3% while distance sailed fell 80.4%and CO₂ per nautical mile rose 0.7%.That points mainly to how much the vessel sailed, rather than the other.
