With a growing density in the cities, we are building more and more compact with fewer space for green areas. At the same time, the biodiversity has been going through extensive changes due to humans’ impact on the planet. Nature-based solutions (NbS) is one of the important tools to cope with climate change and other important challenges of the community. The aim of this study is to create a deeper understanding of what possibilities and limitations there is for Nature-based solution for the Swedish circumstances. This is a qualitative study based upon a literature study and interviews, that unravels what NbS implies, what the project process looks like and how it overlaps with the plan and building law in Sweden. The study shows how to implement NbS to the plan and building process, there are many possibilities to implement but few means to control the outcome through the process. Today the sustainability work is mostly built on minimum requirements, society impacts and on good will. To better implement NbS the study shows that though the environmental impact assessment the work is the most equivalent compared to NbS project process and also has the authority to regulate different protection measures.
