As powertrains diversify in their electrification levels – hybrids, plug-in hybrids, battery electric vehicles and fuel cell electric vehicles – along with the fuel production pathways – fossil and renewable routes – the carbon footprint over their life-cycle heavily depends on their use cases (e.g. driving profile) and context of use (e.g. carbon intensity of electricity). This interactive tool developed by IFPEN and commissioned by Concawe allows to design several scenarios combining these parameters and to compare their environmental performance.
