• The ever-growing populations of cities cause the need of solution finding when it comes to urban logistics or city logistics. Customers demand coenient delivery that meets their needs and rising expectations. Especially in case of the steady growth and development of e-commerce, the fragmentation or “atomization” of deliveries is an increasing burden for urban infrastructure. As a result, the traffic in cities suffers from rising parcel deliveries which in turn impairs the sustainability of city logistics in general. Currently, a range of concepts, that targets the solving of city logistics problems, does exist or is developed. This paper aims to display the variety of city logistics concepts. In a first step, the term city logistics is defined and scientifically framed. Based on that, the authors develop a classification of various city logistics concepts to indicate the estimated relevance and time horizon of becoming a potential city logistics solution. For this purpose, all researched city logistics concepts are described. Moreover, the parallel existence of stationary trade and e-commerce is taken into consideration for the solution finding. In the next step, the identified city logistics concepts are evaluated on the basis of sustainability criteria to outline expected potentials. The knowledge thus gained is then transferred to the city of Leipzig to offer possible last mile solutions for upcoming traffic loads according to the rise of e-commerce. The intended portfolio analysis provides information on the relevance of current and future city logistics trends according to the different sustainability criteria in the age of e-commerce.
