Scope

Main Technical Content: The principles of carbon footprint accounting for microcomputers shall comply with the relevant provisions of the T/DZJN 001—2018 standard. 5. Product Carbon Footprint Calculation 5.1 Functional Unit The functional unit is a single microcomputer, excluding its accessories and packaging materials. The carbon footprint quantification results of the product shall be recorded in terms of the carbon dioxide equivalent per functional unit in the product carbon footprint evaluation report. 5.2 System Boundary The system boundary for microcomputer carbon footprint is set from the manufacturing stage to the use stage. - Manufacturing stage: includes emissions generated during the direct production process and auxiliary production processes of the product. - Distribution stage: emissions generated during the transportation of the product, excluding emissions during storage by distributors and from distributors to next-level distributors or consumers. - Use stage: includes emissions generated during the normal use of the product, excluding emissions from maintenance and repair processes. 5.3 Data Collection, Selection Criteria, Quality Requirements, and Sampling Requirements The data collection, selection criteria, quality requirements, and sampling requirements shall comply with the relevant requirements of the T/DZJN 001—2018 data section. 5.4 Allocation and Calculation 5.4.1 Allocation The allocation shall meet the relevant requirements of GB/T 24040-2008 and GB/T 24044-2008. - Note 1: For auxiliary processes or wastewater treatment processes, the allocation shall be based on production output. - Note 2: If the evaluated product is transported together with other products, the greenhouse gas emissions during transportation shall be allocated based on product weight or other constraints. 5.4.2 Calculation The carbon footprint of the microcomputer is equal to the sum of the GHG emissions during the manufacturing,
