ZHEN HUA 24: CO₂ emissions 2018–2025

ZHEN HUA 24 against its type

Built in 1986, it is 23 years older than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 37,879 gross tonnage it is larger than 90% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 15 vessels in the other ship types category here under the Hong Kong flag, 3.0% of the 499 on the register. The same builder is recorded for 79 other vessels here, one of them a vessel in the other ship types category. The returns for 2018–2025 all give Hong Kong as port of registry.

Its 8,107 t of CO₂ for 2025 is 1.6 times the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 379.9 kg CO₂, 1.6 times the type median of 231.1 kg. It logged 2,157 hours at sea against a median of 2,231 hours for its type that year. 0.6% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 4 years with reported emissions, the highest was 2018 (10,191 t) and the lowest 2024 (1,323 t). Its efficiency percentile within the type went from 69 in 2018 to 70 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025

Position 83 of 119 qualifying other ship typess by EEOI, at the 70th percentile. The dashed line is the type median, 69.3; this vessel reported 93.8.

EEOI divides emissions by transport work, which for this vessel and year was 86,385,189 tonne-miles over 21,342 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 20.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.

From 2024 to 2025, emissions rose 512.6% while distance sailed rose 493.0%and CO₂ per nautical mile rose 3.3%.That points mainly to how much the vessel sailed, rather than the other.
