Dissemination of electric vehicles in urban areas: Major factors for success

The most important recommendation for policy makers is that all monetary and non-monetary promotion measures implemented should depend on the environmental benignity of the electricity generation mix. From society's point of view the promotion of EVs make sense only if it is ensured that a major share of electricity they use is generated from renewables. Since the final goal is not just to increase the number of EVs but to reduce emissions, cities also have to consider other e-mobility options such as trolleybuses, metros, trams and electro buses, as well as promote walking and biking, especially for short distances.
