The report "Life Cycle Assessment of Lead-based Batteries for Vehicles" was commissioned by several major organizations in the automotive and battery industries, including EUROBAT, ILA, ACEA, JAMA, and KAMA. The study aimed to assess the environmental impact of lead-based automotive batteries, including their Global Warming Potential, throughout their life cycle. The study was conducted by Viviana Carrillo Usbeck, Arnav Kacker, and Dr. Johannes Gediga of PE INTERNATIONAL AG. The report provides detailed information on the environmental impact of lead-based batteries, including their energy use, greenhouse gas emissions, and waste management. The study concludes that lead-based batteries have a lower environmental impact than alternative battery technologies, such as lithium-ion batteries. Overall, the report provides valuable insights into the environmental impact of lead-based batteries and highlights the need for further research in this area.
