The project is based on a y-centered research design, including a triangulation of methods to generate and analyze data. In a first step, it brings together existent explanations of activities linked to norm dynamics and empirically examines a broad base of city networks and their activities related to norm dynamics. Further steps are dedicated to examining four city networks and explain their activities linked to norms on security, human rights, health, and digitalization. Methods include interviews, survey research, document, and social network analysis.
