Large volumes of excavated soil and rock are generated in building- and construction projects. These materials need to be transported longer and longer distances due to the densifications of cities. The transportation affects the environment in terms of noise and emissions, but also makes high demands on road infrastructure. To reduce the transport distances an increased responsibility for the excavated rock generated needs to be taken. Responsibility can be increased through an introduction of means of control. Previous studies describe public procurement as an effective tool to increase the responsibility taken by public authorities. Public procurement is regulated by law but the inclusive of environmental requirements is optional, which makes procurement as a tool flexible. The aim of this thesis is to examine public procurement as a tool to control and reduce the environmental impacts from handling, and specifically transporting excavated rock generated in municipal construction projects. The study consists of a case study conducted in Södertörns eight municipalities and a wider analysis that has been carried out in the regions of Stockholm, Västra Götaland and Skåne. The two studies showed that municipal officials generally do not believe that the handling of excavated rock is a municipal responsibility, it lies in the entrepreneurs self-interest to implement regional mass balances. Entrepreneurs instead, consider it to be a municipal problem that can be resolved only when the municipality begins to take responsibility for the excavated rock generated, by example through developing regional plans. As in previous studies, the result indicates that the supplier and purchaser consider the environmental requirements in the procurement process differently. The thesis identify four different factors, which limits the municipalities ability and willingness to take more responsibility in the procurement process regarding the matter excavated rock from construction. These factors are different political position, short term planning, centralization of the procurement units and lack of national and municipal regulations. The study presents that the knowledge in municipal procurement entities is low when it comes to the handling of excavated rock from municipal construction projects. The major knowledge gaps are probably due to the fact that excavated rock for a long time has been seen as an unwanted issue and interest in managing their materials has therefore been low. The knowledge gap must be decreased before the municipalities are able to develop an ethical maturity and take more responsibility in the management of excavated rock. Increased dialogue between different municipal sections and other stakeholders may increase the knowledge.
