CS ZHE JIANG against its type
It is one of 65 chemical tankers here under the Hong Kong flag, 2.8% of the 2,344 on the register. The returns for 2022–2025 all give Hong Kong as port of registry.
Its 3,098 t of CO₂ for 2025 is 44% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 282.9 kg CO₂, 13% above the type median of 250.2 kg. It logged 896 hours at sea against a median of 2,106 hours for its type that year. 4.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2025 (3,098 t) and the lowest 2024 (2,563 t). Its efficiency percentile within the type went from 14 in 2022 to 28 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 381 of 1,348 qualifying chemical tankers by EEOI, at the 28th percentile. The dashed line is the type median, 14.4; this vessel reported 10.7.
EEOI divides emissions by transport work, which for this vessel and year was 290,083,333 tonne-miles over 10,952 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 13.8% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 20.9% while distance sailed rose 8.6%and CO₂ per nautical mile rose 11.4%.
