Battery Electric Vehicles (BEVs) play a key role in decarbonizing mobility but are resource-intensive throughout their life cycle, especially in battery production. Enhancing Resource Efficiency (RE)—maximizing economic value per unit of resource—can reduce global resource consumption. This study analyzes the RE of traction batteries using Multi-Regional Input-Output (MRIO) tables from Exiobase 3 to isolate electric equipment demand and assess resource impacts. The status quo RE is presented, and sensitivity to changes in key drivers is tested. Results highlight manufacturing locations, material hotspots, and strategies for policymakers and industry to improve BEV and battery RE.
