Sustainability | Special Issue : Electromobility for Urban Freight and Logistics

In this Special Issue, we welcome contributions which facilitate the search for win-win solutions where cost-efficient commercial urban transport can be successfully achieved with the use of electric vehicles. Suitable submissions include the adaptation of existing distribution and service logistics systems with the inclusion of electric vehicles (e.g., within city logistics concepts), fleet analysis and routing tools, lifecycle and total cost of ownership (TCO) estimations, cost and environmental impact assessment, etc. Furthermore, we welcome successful case studies demonstrating the applicability of electric vehicles for urban freight transport and logistics.
