On June 21, 2021, the Beijing Municipal Market Supervision and Administration Bureau in China released the local standard DB11/T 1860-2021 “Guidelines for electronic information products carbon footprint accounting” (hereinafter referred to as “Guidelines”). The Guidelines will take effect on October 1, 2021. The Guidelines stipulate carbon footprint targets, calculation scope, functional units, scope of system data collection, data collection and processing, calculation, and report for electronic information products.
Definition of terms
Carbon Footprint (CFP): The sum of the greenhouse gas emissions and absorption of a product, expressed in CO2e.
When determining the carbon footprint of a product, the product scope, such as functional units and system units, the typical time period categories in carbon footprint calculations, and the range of greenhouse gases will be considered and explained. The above range of greenhouse gases includes carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3).
The description of the functional unit should include the main functions of the product system that affect the carbon footprint calculation.
Scope of system data collection
The scope of the system data collection for calculating the carbon footprint of a product includes 2 stages: the manufacturing stage and the use stage of the product.
Data collection and processing
Manufacturing stage: Relevant data will be collected during the manufacturing and transportation of components, the assembly of the final product, and the treatment of exhaust gas, wastewater, and waste generated during these processes.
Use stage: Includes energy efficiency, usage time, usage life, and greenhouse gas emissions related to the power consumption of the product in various usage states.
Product carbon footprint calculating
The formulas for product carbon footprints calculating, calculating greenhouse gas emissions for emissions from fossil fuel combustion and emissions from purchased electricity are clearly defined.
Product carbon footprint report
Include the product name, specifications, functional units, data collection scope of system, and calculation basis.
