Effectively enforced vehicle CO2 performance standards are at the core of any effort to realize lower-carbon transport. EU member states should implement supporting policy measures such as emissions-based vehicle taxes, mandates for electric vehicles, and emissions-based road pricing.

Reviews recent research regarding greenhouse gas emissions from the manufacturing of lithium-ion batteries for electric vehicles. We analyze this research in the overall context of life-cycle emissions of electric cars as compared to conventional internal combustion vehicles in Europe. Finally, we discuss the primary drivers of battery manufacturing emissions and how these emissions could be further mitigated in the future.

Der derzeitige Rückgangs des Dieselanteils zieht keine negativen Auswirkungen auf die Erreichbarkeit der Klimaschutzziele nach sich. Vor diesem Hintergrund sollte ein Festhalten an der derzeitigen Subvention von Dieselkraftstoff für Pkw kritisch hinterfragt und eine Angleichung der Steuersätze für Diesel und Benzin in Erwägung gezogen werden.
