The project CASUAL intends to deliver robust and scientifically sound evidence regarding the question of how to promote sustainable living and consumption patterns by including citizen and consumer perspectives in the governance of urban areas. The project will develop new forms of inclusive urban planning in complex urban governance systems by exploring the urban living lab concept to assess its scope, feasibility and robustness regarding the mobilisation and integration of various stakeholders. The major goal of the project is to create and manage two "Urban Living Labs" at the neighbourhood level in Vienna ("In der Wiesen Ost") and Stockholm (Årsta and Östberga) to generate innovative ideas and scenarios as well as new trade-offs for sustainable urban development. This will be systematically explored and evaluated. In order to inform the work conducted in the urban living labs, three background case studies will be carried out to examine three closely related topics: (i) transit-oriented development and travel behaviour (The Netherlands); (ii) mobility patterns and lifestyles (Austria); and (iii) housing re-development and preferences (Sweden). The findings and derived "good practices" from this project shall be analysed regarding their transferability to other social, institutional and issue-based contexts.
