| Summary: | This thesis aim is to study the usage and experience of the sustainability tool SUNRA (Sustainable National Road Agency) as well as the tool's contribution to the Swedish Transport Administration’s sustainability work in the East link project. The usage and the experience with the SUNRA tool is presented partly based on the interviews conducted and by comparing the previous research found in field of sustainability tools. The ambition of ERA-NET Roads was to provide a sustainability tool that is divided into three frameworks and takes a holistic approach to the sustainability issue of traffic authorities in Europe. This study highlights areas that the research emphasizes; Sustainability work and major projects, infrastructure projects and the overall perspective, sustainability tools in projects, and communication of sustainability work. Through a qualitative semi structured interview study, five themes were identified: why SUNRA was chosen, utility usability, structure of sustainability work, organization around SUNRA and how the communication appears in the East link project. The result of the study shows that the usage of the SUNRA tool in many ways correspond with the earlier research, by taking a holistic perspective on the sustainability work and to contribute with a starting point in the sustainability work. The result of the study also shows that the SUNRA-tool doesn’t line with the earlier research when the shaping of and the communication with the tool has not been satisfactory.
