Scope

Main technical content: The principles for calculating the carbon footprint of mobile communication handsets shall comply with the relevant provisions of T/DZJN001-2018. 5 Carbon Footprint Calculation 5.1 Functional Unit The functional unit is a single mobile communication handset, excluding the accessories and packaging materials provided with it. The product carbon footprint evaluation report shall record the quantified results of the product carbon footprint in terms of the carbon dioxide equivalent per functional unit. 5.2 System Boundary The system boundary for calculating the carbon footprint of mobile communication handsets 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 distribution of the product, excluding emissions generated during storage by distributors and emissions generated during the transfer of the product from distributors to the next-level distributors or consumers. - Use stage: Includes emissions generated during the normal use of the product, excluding emissions generated during the maintenance and repair of the product. 5.3 Data Collection The criteria for data collection, selection, quality requirements, and sampling requirements shall comply with the relevant requirements of the data section of T/DZJN001-2018. 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 generated during transportation shall be allocated based on the product weight or other constraints.
