How to make electric vehicle traffic carbon–free

Abstract The increase in electromobility could help achieve the zero–carbon target for vehicle traffic by 2050. However, the use of electricity from CO2-containing sources such as coal, oil, or gas speaks against this. This is why e-mobility is sometimes called a deception. Extensive government subsidies for the purchase of e-mobiles are criticized because they do not or only inadequately fulfill their ultimate purpose, namely, the decarbonization of vehicle traffic. The new method of state e-mobility funding presented here proposes subsidizing fewer EV purchases but using the amount released to promote the expansion of renewable energies to the extent that sufficient clean electricity is available for every new electric vehicle. This will make vehicle traffic 100% carbon–free. An empirical study strongly suggested that this method increases the acceptance of e-mobility subsidies among the population.
