 The study compares alternative powertrains and liquid fuels based on renewable electricity for light-duty vehicles, LDVs, to achieve necessary CO2 emission reductions in the transport sector while considering system-wide implications along other sustainability dimensions. Results indicate that greenhouse gas emissions drop significantly in all mitigation scenarios, but impacts increase in several non-climate change impact categories. Changes in mobility lifestyles and industrial processes are crucial to reduce environmental impacts from a climate-friendly LDV fleet across all categories.
