JIAYAO against its type
Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 33,044 gross tonnage it is smaller than 57% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 637 bulk carriers here under the Hong Kong flag, 7.8% of the 8,138 on the register. The same builder is recorded for 95 other vessels here, 41 of them bulk carriers. Its MRV returns name it SANIA for 2018 and JIAYAO for 2025. The returns for 2018–2025 all give HONG KONG as port of registry.
Its 655 t of CO₂ for 2025 is 80% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 328.6 kg CO₂, 26% above the type median of 260.7 kg. It logged 171 hours at sea against a median of 1,200 hours for its type that year. 27.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 77.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, 2023, 2024, so the series has gaps.
From 2018 to 2025, emissions fell 77.9% and CO₂ per nautical mile fell 0.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
