Electric vehicles and renewable energy sources in transportation played a significant role in promoting sustainable transportation systems. The overall performance of the electric vehicle is highly dependent on the electricity mix consumed during their production and use phase. Therefore, a comprehensive and dynamic assessment is necessary to provide accurate guidance to users and policymakers. Therefore, this study presents a comparative cradle to grave life cycle analysis of electric vehicles in 10 selected countries using the current and future electricity mix scenarios. We present the environmental footprint of vehicle production, transportation, and use phases. The results revealed that EVs in China with current (2019) and future 2025 electricity mix scenarios had a higher impact than all other EVs. In contrast, EV with 2030 Norway electricity mix was an optimal choice and has the least environmental impact in most of the selected categories. Moreover, it was also found that all EVs with 2030 electricity mix had lower environmental damages than EV 2019 electricity mix. Besides, this study outcome indicated that the use of clean energy could help to decrease the environmental impact and mitigate climate change all around the globe.
电动汽车和可再生能源在交通运输中发挥了重要作用，促进了可持续交通系统的发展。电动汽车的整体性能高度依赖于生产和使用阶段所消耗的电力组合。因此，需要进行全面和动态的评估，为用户和政策制定者提供准确的指导。因此，本研究使用当前和未来的电力组合情景，对 10 个选定国家的电动汽车进行了比较全生命周期的摇篮到坟墓的生命周期分析。我们展示了车辆生产、运输和使用阶段的环境足迹。结果表明，中国的电动汽车在当前（2019 年）和未来 2025 年的电力组合情景下，比所有其他电动汽车的影响都更大。相比之下，使用 2030 年挪威电力组合的电动汽车是一个最佳选择，在大多数选定类别中具有最小的环境影响。此外，还发现所有使用 2030 年电力组合的电动汽车的环境损害都低于 2019 年电动汽车的电力组合。此外，本研究结果表明，清洁能源的使用可以帮助减少全球范围内的环境影响和减缓气候变化。
