- Carbon dioxide has long proven to be one of the greenhouse gases that affects our planet's climate and environment. With the forthcoming European Union goals and Sweden's own net-zero goal, it is required that the building and real estate sector works with climate-smart materials to construct future buildings. The net-zero goal by 2045 requires a common effort from all companies to find innovative solutions in order to reduce carbon dioxide emissions sharply. This study investigates how aware and active the building and real estate sector is in climate-smart concrete (CSC) through a survey and comparison of environmental product declarations (EPDs). Climate-smart is a term for concrete that contains a lower percentage of Portland cement clinker than traditional concrete. This research aims to examine how far the development has taken place and to evaluate how the market has adopted the newly available products. It is als assessed which alternative additive materials are the most common as well as advantages and disadvantages of the CSC. A questionnaire is created, and the survey is sent out to companies. A comparison is made between three different EPDs of the CSC and two references for concrete with the ordinary Portland cement clinker. Reference concrete 1 is a standard value, and reference concrete 2 is an EPD value. A reference building is used to calculate the volume and weight of its utilized concrete. The three types of the CSC are compared with the reference concrete 1, and the results show a carbon dioxide reduction of 29.3%. However, the comparison of these three types of the CSC with the reference concrete 2 demonstrates a carbon dioxide reduction of 2.8%. In addition, it is concluded that the future will require the building and real estate sector to invest time and training to work with the CSC further.
