日本語
中国のEVを対象に、製造・使用・廃棄の各段階の炭素排出と算定手法を121件の文献で整理したレビュー。製造時のembodied排出がライフサイクル全体の30%超を占め、使用段階は系統電力の炭素強度とV2G運用に大きく依存する。二次利用電池とクローズドループリサイクルが初期生産負荷を軽減し、企業・政策向けの脱炭素経路を提示する。
English
A structured review of 121 studies on life-cycle carbon emissions of EVs in China, covering manufacturing, use, and end-of-life stages. Manufacturing embodied emissions exceed 30% of the total, while the use stage offers the largest reduction potential tied to grid carbon intensity and V2G scheduling. Second-life batteries and closed-loop recycling reduce upstream burdens, informing enterprise and policy decarbonization pathways.

📄 Abstract（原文）
Accelerating the low-carbon transition of transport is essential to addressing global climate change. Although the rapid growth of the electric vehicle (EV) fleet highlights the environmental benefits of electrified mobility, carbon-intensive upstream electricity generation and energy-intensive battery production continue to constrain the life-cycle emissions reduction potential of EVs. Focusing on China, this structured narrative review examines 121 core references from 2004 to 2026 to synthesize carbon-accounting methods and emissions across the manufacturing, use, and end-of-life stages. A supplementary keyword co-occurrence analysis of 1180 Web of Science records provides an overview of the research field. The reviewed evidence indicates that embodied emissions from manufacturing account for more than 30% of total life-cycle emissions, making this stage important to life-cycle decarbonization. The use stage offers the greatest emissions reduction potential and is closely linked to regional grid carbon intensity and vehicle-to-grid (V2G) scheduling. At the end of life, second-life battery use and closed-loop recycling can reduce the burden associated with initial production and support material circularity. Drawing on these findings and the development of China’s EV industry, this review proposes decarbonization pathways for enterprises and policymakers to support the coordinated development of the transport and energy sectors.
