The “Global Electric Vehicles on the Road” metric represents the total number of electric vehicles (EVs) currently in use around the world. This includes all forms of electric vehicles, such as plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs), and fuel cell electric vehicles (FCEVs).This metric provides an indication of the adoption rate of electric vehicles globally. It is a critical metric in understanding the transition from fossil fuel-based transportation to cleaner, more sustainable electric transportation, as part of broader efforts to mitigate the effects of climate change.
