Abstract

Under the global "dual-carbon" framework, decarbonizing supply chains has become critical for corporate green transformation. Using Lenovo Group as a case study, this work constructs a comprehensive supply chain carbon measurement system by integrating life cycle assessment (LCA) and economic input-output modeling (EIO-LCA). The system identifies high-emission linkages and proposes targeted optimization strategies. Findings reveal that Lenovo's supply chain emissions concentrate predominantly in raw material procurement and cross-border logistics. Implementing green purchasing agreements, optimizing multimodal transportation routes, and deploying a digital carbon management platform reduced emission intensity by 18.5%. This research establishes a replicable emissions-reduction methodology for electronics manufacturing while providing theoretical support for policymakers and industry practitioners.
