This paper discusses insights from the assessment of eco-efficiency in electric mobility, presented at the STOA Lunch Debate in Brussels on May 7, 2013. Key topics include the evolution, environmental impacts, and future outlook of electric vehicles (EVs) and other technologies like hydrogen and hybrid cars. It explores the balance between electric mobility being part of the solution versus becoming a problem. The study emphasizes the importance of efficiency, lifecycle greenhouse gas emissions, battery developments, and recycling strategies to promote sustainable mobility.

  2. From Hype to Analysis Againandagain: hopingfornewmobilitytechnologiesthataresustainablewithoutneedforchangingbehavior: • Electriccarsofthe 90ies • Natural gas cars • Hybrid cars • Hydrogen cars • Electriccarsoftoday … but emobilityis not THE solution… Whenisemobilitypartofthesolution („opportunity“),whenisitpartoftheproblem („risk“)?

  3. Scopeofthestudy • Future development of cars, power supply and user behavior for the years 2012, 2020, 2035 und 2050. • eMobility = electric engine + >50% power from grid: H2-cars and hybrids are excluded Combustionengine
