Differences in vehicle electrification policies and optimal transition periods across countries

Year: 2025

Type: article

Abstract: Transitioning to electric vehicles has become a global carbon neutrality policy goal. However, vehicle electrification may have different outcomes depending on the energy mix scenario, average driving distance, vehicle lifetime, and vehicle manufacturing supply chain in a country. Hence, in this study, we applied the life cycle optimization approach to identify optimal car replacement periods, which would yield the lowest cumulative CO 2 emissions for 2020–2050 in six countries: China, Germany, Finland, India, Japan, and the United States. The results showed that a discrepancy is evident between the existing policies of Germany, Japan, and the United States. To optimize CO 2 emission reduction, these policies necessitate revision. Additionally, given the profound impact of region‐specific parameters, such as driving distance and vehicle preferences, the United States should endeavor to develop state‐specific policies predicated upon detailed state‐level data.
