本論文は、リチウムやコバルトなどの金属資源制約を内生化した統合モデルを開発し、電動車の普及見通しが過大評価されるリスクを定量化。中国を対象に、金属制約を無視すると2060年のEV保有台数を最大42%過大評価し、CO2排出量と移行コストを過小評価することを示す。日本やドイツなど主要自動車生産国にも示唆を与える。
English
This study develops an integrated model incorporating critical metal constraints to evaluate electric vehicle adoption pathways. For China, ignoring metal shortages would overestimate 2060 EV ownership by up to 42% and underestimate carbon emissions and transition costs by 57% and 6%, respectively. Findings offer insights for major vehicle-manufacturing countries like Japan and Germany.

📄 Abstract（原文）
Widespread adoption of electric vehicles is crucial for low-carbon development. However, a potential shortage for the raw metal materials (e.g., lithium, cobalt, and nickel) may become the primary constraint. Previous studies have largely overlooked metal constraints on vehicle electrification pathways, leading to overly optimistic projections for electric vehicles. Hence, this study develops an integrated model, to endogenously capture the supply-demand imbalance of critical metals, and propose sustainable vehicle electrification strategies that can ensure metal security and carbon mitigation for passenger car sector. Here we find that neglecting critical metal constraints would overestimate electric vehicle ownership by up to 42% in 2060 and underestimate carbon dioxide emissions and transition cost by up to 57% and 6% during 2025–2060, respectively for China. We further provide more feasible electrification pathways under multiple uncertainties. Findings here offer insights for major vehicle-manufacturing countries, like Japan and Germany; and mitigate potential cascading disruptions in the global vehicle supply chain. Ignoring critical metal constraints would overestimate electric vehicle ownership and underestimate transition costs and carbon emissions, according to an integrated metal-energy-carbon optimization model.
