Electromobility is a very promising sustainable technology for reducing emissions and energy consumption in the transportation sector. During the last year, electric vehicles are gaining increased attention in Greece and various incentives and actions favor their use and purchase. The aim of this work is to present a complete Action Plan developed for the Region of Attica, the largest region in Greece, for promoting electromobility through the implementation of concrete and targeted actions, based on the results of the region’s current situation analysis. The actions classified in three primary axes, infrastructure, equipment and promotion, include campaigns organization, installation of charging infrastructure in strategic locations and substitution of part of the regional vehicle fleet with electric ones. The Action plan presented in this work gives a complete framework of the steps that should be followed from the analysis of the current situation to the formulation and implementation of the actions and can be used as in inspiration and a guide for other regions interested in electromobility field.
