Abstract:
In this article, the recently published SPOTTER approach, which allows for identifying potential supply disruption impacts along the entire supply chain within life cycle sustainability assessment in the short term (i.e., < 5 years), is applied to a case study addressing the cobalt and aluminum supply chains of electric vehicles (EVs) used in Switzerland. Existing studies within the field assessing supply disruption impacts for EVs and other technologies focus on impacts related to raw material supply and thus neglect impacts along full supply chains. The present study identifies hotspots and overall impacts along the full supply chains by analyzing six supply disruption events (i.e., geopolitical instability, child labor restrictions, trade barriers, price volatility, limited recyclability, and economic resource depletion) for two impact categories (i.e., cost variability and limited availability). Identified hotspots suggest that supply chains are potentially disrupted mainly through events occurring in Asian, African, or other developing countries and affecting the Western economies. The highest risks are indicated in relation to the supply of EVs, EV wiring, traction batteries, cobalt powder, and cobalt ore. Suitable measures to mitigate these supply risks are suggested showing that some of the suggestions could not have been made based on the results of existing studies.
摘要:
在这篇文章中,最近发表的SPOTTER方法,这可以在短期内在生命周期可持续性评估中识别整个供应链的潜在供应中断影响(即,<5年),应用于针对瑞士使用的电动汽车(EV)的钴和铝供应链的案例研究。现场现有的评估电动汽车和其他技术供应中断影响的研究侧重于与原材料供应相关的影响,因此忽视了整个供应链的影响。本研究通过分析六个供应中断事件(即,地缘政治不稳定,童工限制,贸易壁垒,价格波动,可回收性有限,和经济资源消耗)对于两个影响类别(即,成本可变性和有限的可用性)。识别出的热点表明,供应链可能主要通过亚洲发生的事件而中断,非洲,或其他发展中国家,并影响西方经济。与电动汽车的供应有关的风险最高,EV接线,牵引电池,钴粉,和钴矿。建议采取适当的措施来减轻这些供应风险,这表明根据现有研究的结果无法提出一些建议。
