This chapter investigates environmental partnerships in the city of Cleveland (USA), focusing on how they affect the problem-solving capacity of local communities, in terms of access to environmental information. The case study shows how the innovation agenda of the regulatory agencies, the empowerment agenda of the environmental advocacy community and the aspirations of community-based organizations became linked two each other. Key factor in the success of the partnerships has been the broker roles played by non-governmental organizations. At the national level, NGOs have an important role as ‘information-intermediaries’ in the nationwide infrastructure for environmental information. In Cleveland, they fulfilled initiating and facilitating roles as ‘interaction intermediaries’ in the emergent partnerships.
