The vehicle tax and the privileged income tax treatment of company cars are central obstacles on the way to fairer and more climate-friendly mobility. A new study by FiFo Cologne and RWI Essen shows the decisive role of the purchase decision for the structure of the passenger car fleet. Based, among other things, on household surveys conducted by RWI, FiFo drafts reform models for both of the central levies that still stand in the way of the transformation today. Now the full version of the study financed by Agora Verkehrswende has been released.
