Research questions 'zero-emission' claims of electric vehicles in Germany

Sebastian Viehmann published a commentary arguing that labeling electric vehicles as completely “zero-emission” is misleading. He notes that the carbon footprint depends heavily on how the electricity used to charge them is generated, especially when fossil-fuel plants supply power during high-demand hours. Citing research from Karlsruhe Institute of Technology and the Technical University of Munich, the commentary states that battery-electric vehicles typically reduce CO2 emissions by only about 41% compared to combustion engines.

The commentary challenges the core narrative surrounding electric vehicles, suggesting that their environmental benefits are less pronounced than commonly portrayed. This raises questions about the true climate neutrality of battery-electric vehicles, depending on power generation and raw material extraction methods.
