TIAN YOU against its type

Built in 2018, it is 11 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 38 general cargo ships here under the China flag, 1.2% of the 3,081 on the register. The same builder is recorded for 114 other vessels here, one of them a general cargo ship. China Ocean Shipping Co., Ltd. is linked to 3 vessels on this register. The returns for 2018–2025 all give Guangzhou as port of registry.

Its 6,051 t of CO₂ for 2025 is 2.1 times the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 259.0 kg CO₂, 2.1 times the type median of 122.2 kg. It logged 1,911 hours at sea against a median of 3,044 hours for its type that year. 10.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2019 (14,200 t) and the lowest 2018 (3,513 t). Its efficiency percentile within the type went from 4 in 2018 to 23 in 2023 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023

Position 78 of 331 qualifying general cargo ships by EEOI, at the 23rd percentile. The dashed line is the type median, 21.1; this vessel reported 12.5.

Across the 3 ranked vessels operated by China Ocean Shipping Co., Ltd., the median percentile is 23. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 934,200,640 tonne-miles over 47,897 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 72.3% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 47.3% and CO₂ per nautical mile rose 7.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
