Environmental Impact Assessment for Flemingsbergsdalen 2020-01-16 Foreword The municipality of Huddinge has formulated an ambitious vision for developing the area of Fleminngsbergsdalen. With the aim of developing a new integrated urban centre with new businesses, commerce, housing and social services, the project entails significant construction work and an intensification of urban activities. This, in turn, can potentially lead to substantial environmental impacts. The present report is an assessment of the potential environmental impacts of the Flemingsbergsdalen development. The assessment and report were produced by students of the masters’ level course Case Studies in Environmental Impact Assessment at Stockholm University. The Environmental Impact Statement presented here is the result of rigorous research by the students during a period of six weeks between December 2019 and January 2020. The results and views presented in this report are those of the students alone, and do not represent the position of Stockholm University. We would like to acknowledge all who have offered help and input during this process.
