中国机动车零部件及配件碳足迹量化迎来专门标准

Core Viewpoint - The approval and release of the group standard "Quantification Methods and Requirements for Carbon Footprint of Greenhouse Gas Products in Motor Vehicle Parts and Accessories" fills a gap in carbon footprint accounting standards for the motor vehicle parts and accessories industry in China, aiming to enhance competitiveness and address existing issues in carbon footprint quantification [1][2]. Group 1: Standard Overview - The standard was developed by the China Quality Certification Center in collaboration with the China Automotive Engineering Research Institute, Shanghai Motor Vehicle Testing and Certification Technology Research Center, and over 20 leading industry enterprises, covering the entire supply chain [1]. - It defines terminology, quantification scope, inventory analysis, impact assessment, and reporting requirements for carbon footprints, applicable to core components like body assemblies, engine assemblies, and brake systems, as well as accessories like lamps and seats [1]. Group 2: Key Innovations - The standard introduces a "lifecycle + tiered accounting" framework to clarify what to account for and how, establishing clear system boundaries and differentiating functional units based on component types to avoid accounting biases [2]. - It addresses data collection challenges by standardizing data collection and clarifying allocation principles, including a "data sharing whitelist" mechanism to improve supplier cooperation and data disclosure [2]. - The standard also standardizes reporting and labeling requirements to ensure traceability and verifiability, providing a unified reporting framework that includes essential elements like product descriptions and carbon emission inventories [2].
