Previous research has shown that the existence of after school program is beneficial for children's health and their academic performance. Lorensborgsskolan, an elementary school situated in Malmö, implemented a project called “From movement in school to being active in organized sports” where they started a school sport organization. The project seeks to increase the amount of children active in external sport organizations and to make the transition more accessible. The project collaborated with Hemmaplan which is an initiative from the Scanian Basketball Federation. Therefore, the aim of this study was to discuss the prerequisites for implementing Lorensborgsskolans project “From movement in school to being active in organized sports” from a sustainable perspective. The sustainable perspective contains three concepts: social, environmental and economical. Three research questions has been formulated.How was the preparation of this project in relation to sustainability?What challenges can be identified when implementing this project?What benefits can be identified when implementing this project?Interviews, observation and document analysis were the methods used in this research and the data was analyzed through a six step coding process. The result and analysis were divided in three paragraphs named after the research questions connected to the theory. The research findings indicate how this project would give the children a protective factor outside of school. According to the collected result the children should be given the access to pursue sport in the entire city of Malmö and to work on their social skills. In conclusion, an external analysis should have been done before the implementation of the project. The financial aspect is identified as a challenge. For the children to be a part of the school’s sport organization is free of charge in contrast with external sport organizations where this does not imply.
