Title: How can circular economy contribute to social sustainability on a district level? Social sustainability is an idea that is key in further developing sustainability programs which highlights the importance of the actions of individuals in society. In the process of determining whether circular economy can contribute to social sustainability on a district level, two important theories were identified; social capital and place-based identity. This was due to the fact that they embody the major aspects that make up social sustainability. The theories will be studied by analyzing literature and an interview to strengthen the facts taken from the studied literature. The thesis concerns the concepts sustainable development, planetary boundaries, Doughnut Economics, regenerative cities and Doughnut Districts that together create a context for the further analysis regarding circular economy, social capital and place-based identity. These theories are the main focus of the study, and will therefore be studied more thoroughly. In this thesis, sustainable development is defined as the kind of development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The theory of Doughnut Economics encompasses key limiting factors such as the limited natural resources available and the power of social behaviour, which constitutes the boundaries for human living space. Neighbourhoods developed and shaped by the concept of Doughnut Economics are referred to as Doughnut Districts. Regenerative cities can be described as cities that are in harmony with their surroundings, as well as the ecosystem. Circular economy is an economic model which aims for a circulation of resources while achieving economic growth in combination with a minimal environmental impact. Meanwhile, social capital involves the intricate relationships between individuals in society, which allows the society to function more efficiently. This includes organizations and communities that through establishing norms and utilizing their influence produces positive changes. Place-based identity is characterized by an individual’s cultural and emotional connection to a specific place. The unity and pride of individuals within a certain city can be important indicators for how socially sustainable the aforementioned city is. This is a major root for good social relationships within a district, which in effect make individuals feel more welcome and provides a sense of belonging. Combined with the aspects of circular economy, solutions that strengthens circular resource flows, while allowing communities to be used as sharing networks in purpose of maximizing the use of products are suggested. This would create an environment in which a growing ground for innovation comes naturally. This will be achieved by utilizing an accessible compound system and commercial actors, which includes local creative competences. This provides a local anchoring that leads to positive norms and trust by thrust between habitants and their influence on their local environment. The real estate firm Vasakronan is joining forces with Urban Minds to develop a community, Norra Kymlinge, to become a district driven by the aforementioned sustainable principles. This concept can be combined with ideas about the circular economy model. As for the relation between circular economy and social sustainability, the recommendations aim to support the model which constitutes a framework for the district.
