Welcome to the cars CO2 comparator!

This tool shows the life-cycle assessment of greenhouse gas emissions from passenger cars in real-world conditions. As powertrains diversify in their electrification levels – hybrids, plug-in hybrids and battery 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.

User Guide

To help you out navigating through this interactive tool, Concawe has developed a tutorial and user guide. They will allow you to understand what is a life-cycle assessment or what is the difference between hybrids, plug-in hybrids and battery electric vehicles but also what is tank-to-wheel, well-to-tank or well-to-wheels.
