The construction and real estate industry is one of Sweden's largest consumers of energy andraw materials. According to figures from Boverket, the building industry was responsible for21% of Sweden's total greenhouse gas emissions in 2019. If Sweden is to fulfil its commitmentsunder the Paris Agreement and at the same time achieve the climate goals for the 2030 Agenda,resourceefficient measures are required immediately. The transition to circular economy can bea vital step in this necessary change. In circular economy, it is crucial to eliminate waste andpollutants which can be achieved by increasing efficiency and maintaining products andmaterials in a circular cycle. The aim of this study is to examine which strategies can be applied to implementing circulareconomy in the construction industry and what opportunities and obstacles they entail. I havealso investigated whether life-cycle assessment can be an effective tool for this implementation.To answer these questions, interviews have been carried through with researchers and businessrepresentatives who have extensive knowledge of sustainable construction and who arecommitted to finding solutions to combat climate change in the construction industry. Anextensive literature study has also been performed. The results indicate that there are several opportunities and sought-after measures with thecircular economy concept, of which the most significant one is its potential to increase resourceefficiency and thereby generate climate benefits. Strategies for the implementation of CEinclude methods such as circular procurement, design for deconstruction, material passports,upcycling and reversible building design. New smart business models can also generate newrevenues and create more employment opportunities. Challenges highlighted in the study are above all lack of financial incentives. For instance, inmost cases, it is at present more profitable to buy virgin than secondary materials. The lack ofspace for intermediate storage of materials to be reused is also a challenge. There is often a lackof knowledge with suppliers and customers. In addition, there are several legal issues regardingthe division of responsibilities and finally the need of more efficient policy instruments.
