The Swedish government set a climate goal until the year 2045, to not produce any greenhouse gases until 2045. This study is based on the problems surrounding the climate impact from the construction and real estate sector in Sweden. The construction company Skanska has made a major contribution with the recently new project Juvelen, which today is Sweden's most sustainable building. The demand for constructing buildings with lesser environmental impacts is increasing and constructions as Juvelen may be an important factor to achieve climate goals. Purpose: This study was done to determine the carbon dioxide emissions during the construction phase of Juvelen, which includes the production phase and transports to the construction site, as well as the operational phase. Method: This study is based on a literature study, case study, and a reference object. During the case study, interviews were conducted with various people who have participated in the production of Juvelen. The carbon dioxide calculations consisted of EPD reports obtained from Strängbetong and VSAB. The carbon dioxide calculations for the operational phase were performed through different scenarios with three different scenarios types of energy. Results: The result for Juvelen's carbon dioxide emissions during the construction phase, based on the quantitative data that had obtained from Strängbetong and VSAB, was approximately 3,568 tonnes of CO2e. Renewable High had an emission of 96,472.61 kg CO2e during the 50-year analysis period. Renewable Medium received a sum of 2,519,339.7 kg CO2e and Renewable Low 11,961,913.29 kg CO2e. The 100-year analysis period for the operational phase showed the double value of the 50-year analysis period. Based on the current study and an interview with Ambjörn Gille, it appears that Skanska is making efforts to achieve climate goals by 2045. Conclusions: The conclusion that the work came to was that to achieve the climate goal of net-zero emissions, its necessary that the entire construction and real estate sector needs to adapt, apply new and innovative technology. The differences that emerged from the comparison of the production, operating phase for Juvelen were the choice of material, construction process, and method for construction of Juvelen and the choice of energy scenario.
