Standard Introduction
This standard was drafted by CESI together with a broad consortium that includes display panel makers (BOE), certification bodies (CEPREI), and academic institutions (University of Science and Technology Beijing). Issued in April 2025 and effective November 2025, it requires facilities with major emission sources exceeding 3 tCO2e/h to implement online monitoring systems.
The document also references ISO 14064-1 and IPCC guidelines, so the monitoring framework aligns with international carbon accounting practice while being tailored to the specific production processes of China's electronics sector.
