REN JIAN 17 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 42,112 gross tonnage it is smaller than 52% 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 660 other vessels here, 231 of them container ships. The returns for 2021–2025 all give Haikou as port of registry.
Its 28,540 t of CO₂ for 2022 is 1.9 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 512.5 kg CO₂, close to the type median of 539.7 kg. It logged 3,775 hours at sea against a median of 2,699 hours for its type that year. 1.2% of its 2022 emissions were at berth; the median for container ships was 4.2%. Its efficiency percentile within the type went from 62 in 2021 to 83 in 2022 (lower is more efficient). Of the 2 sister ships listed below with a 2022 return, 1 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2022
Position 1,315 of 1,589 qualifying container ships by EEOI, at the 83rd percentile. The dashed line is the type median, 16.9; this vessel reported 34.2.
EEOI divides emissions by transport work, which for this vessel and year was 835,469,262 tonne-miles over 55,682 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 19.9% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2021 to 2022, emissions fell 19.9% while distance sailed fell 23.1%and CO₂ per nautical mile rose 4.2%.That points mainly to how much the vessel sailed, rather than the other.
