The first part of this thesis focuses on the theory of a car free city. It does a shallow dive into the theory on garden cities by Ebenezer Howard and how his plans can function as a starting line for this thesis. Furthermore, we take in the concept of how to Copenhagenize a city with Copenhagen itself as a point of interest. The thesis also adds on an answer of what will happen with the cars when they are moved out of the city.A couple of case studies are added as base for the understanding of how this kind of project can function. However, as this thesis is in a new field of study these cases are only partially relevant to the concept since a perfect case does not exist yet.This thesis should serve as an eye opener for both the general public and private investors and municipalities alike. Nowadays as more and more people are focusing green energy and how to minimize pollution in accordance with the Paris decree. A large factor will be on how to modernize our cities. This thesis illustrates the concept of removing the cars from the cities and how such a city infrastructure could work. Also showcases the authors own project that is created in accordance with the concept where he has created the city center for an area that is developed for a car free city.
