REN JIAN 23 against its type
Built in 2009, it is 1 year newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 40,487 gross tonnage it is smaller than 55% of the other 3,000 container ships with a recorded tonnage. It is one of 31 container ships here under the China flag, 0.9% of the 3,495 on the register. The same builder is recorded for 563 other vessels here, 243 of them container ships. The returns for 2021–2025 all give haikou as port of registry.
Its 26,647 t of CO₂ for 2022 is 1.7 times the median of 15,388 t among the 1,858 container ships on this register that reported for 2022. Per nautical mile it emitted 411.1 kg CO₂, 24% below the type median of 539.7 kg. It logged 4,743 hours at sea against a median of 2,699 hours for its type that year. 1.6% of its 2022 emissions were at berth; the median for container ships was 4.2%. Its efficiency percentile within the type went from 66 in 2021 to 60 in 2022 (lower is more efficient).
No EU/EEA voyages were reported for 2023, 2024, 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 959 of 1,589 qualifying container ships by EEOI, at the 60th percentile. The dashed line is the type median, 16.9; this vessel reported 20.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,273,134,735 tonne-miles over 64,816 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 46.1% higher than in 2021, for EU/EEA voyages only.
From 2021 to 2022, emissions rose 46.1% while distance sailed rose 58.4%and CO₂ per nautical mile fell 7.8%.That points mainly to how much the vessel sailed, rather than the other.
