This report addresses the issue of sustainability and how it can be achieved through David Sims criteria for Soft City. I will analyse existing frameworks that measure cities based on their efforts to become more sustainable and extract the indicators that are most relevant to Soft City which will allow me to form a Soft City Index. This framework will then be applied to Copenhagen where I will score the city on its ability to mitigate climate change through improving their mobility. Ultimately determining that Copenhagen is a Soft City.
