This work deals with the study and selection of the new structure ecological transport systems, taking into account financial and technological conditions. The first chapter describes the implementation of ecological vehicles from a global perspective. This section explains why the introduction of ecological vehicles is necessary in the transport system and what concrete steps have been implemented for this. In the second chapter, the technical possibilities for the design of vehicles are presented with alternative drives. In the third chapter, the information obtained from the relevant literature, summarizes the guidelines and technology vision and the individual alternatively powered vehicles are compared to each other for comparison. In the second part of the work on the market new ecological transport systems are listed. These provide an initial basis for subsequent selection structure that is supported by a calculation tool for evaluation of transport systems from an economic and environmental perspective. Finally, the implementation of the selection structure is in a medium sized company. This work provides an overview of the characteristics of the possible technologies of ecological vehicles and their introduction into a medium sized companies using both financial and ecological conditions.
