In Sweden, the construction sector accounted for 21% of total greenhouse gas emissions in Sweden in 2020. Sweden's climate goal for reducing these emissions is to have net zero emissions by 2045. The construction sector has identified that a large part of the emissions occurs during the operation phase, but that there are also a lot of emissions from the materials used during the production phase. This work aims to identify opportunities and obstacles with reuse, identify the incentives and motivations required for reuse to be introduced on a large scale and identify which constructions are best suited for reuse from an economic and climate point of view. The methods used in this work have been qualitative interviews from employees at the company Cobab, this method aims to answer the questions regarding incentives and opportunities and risks of reuse. To answer the question regarding material selection, the case study method has been chosen to obtain data for calculations. The result is based on the respondents' answers from their experience regarding reuse and their company's view of reuse as well as the case study that was done on a number of projects that provided a basis for calculations. The work has shown that obstacles to reuse are the lack of access to reusable materials and that the clients rarely plan for reuse as it is complicated and can be costly in the current situation to reuse on a large scale. One possibility with reuse is that materials that otherwise need to be sorted as waste can be reused, saving construction companies money and contributing to less emissions. Materials suitable for reuse today are brick, wood, plaster and concrete. However, this is affected by the types of constructions in which the materials are used in. The construction that is most suitable for reuse is interior walls as this construction contains the greatest amounts of material.
