In recent years much research has focused on the methodological development of LCA, why the LCA is a widely applied method, especially in the construction industry [28]. In addition to methodological approaches, application at an early design stage of buildings is also under continuous development [29; 30; 31; 22]. Numerous studies also showed the application of LCA for comparing variants of materials, construction elements, or buildings to evaluate the environmental impacts and to make sustainable decisions based on the results [32; 33; 34; 35; 36]. The rapidly growing field of LCA \"n th' construction industry is reflected in numerous literature studies. Studies examined the application of LCA in the general context of the construction industry [36; 37], and specifically the LCA application in the early project or design phase of buildings [38; 39]. Further literature studies addressed LCA with a focus on embodied emissions and emphasized its importance in consideration of total emissions [17; 40]. In this context, literature studies of LCA application for a wide variety of materials, such as timber, brick, concrete, or insulation materials, are also available [41; 42; 43; 44]. Regarding construction materials, other studies went further into detail and investigated the application of LCA on those individual components of these materials using literature studies. These include, among others, the application of LCA to aggregates or cement mortar [45; 46]. There are also already literature studies on the application of LCA for individual life cycle phases, such as the refurbishment phase or the end-of-life phase [47; 48]. A recent study also analyzed the \"evel'pment of LCA in European policy. The results show that LCA is increasingly mentioned in policy, but the development of new and mandatory requirements related to LCA is still limited [45]. However, it appears that early assessment of the environmental performance of buildings will be mandatory in the future, but the voluntary wide practical application of LCA does not exist yet. Based on this observation, we were interested in determining the current status of LCA application in the building tendering and awarding processes. The first part of this study analyzed the question of whether LCA was applied in the procurement phase of buildings from the perspective of the literature. If LCA was not applied in the procurement phase of buildings, in the second part, we aimed to investigate why it was not applied and what the obstacles to implementation from a practical perspective were. For this purpose, in this article, the main stages of the sociological research framework, (i) choosing a research topic, (ii) conducting a literature review, (iii) measuring variables and gathering data, (iv) analyzing data, and (v) drawing a conclusion, were applied in this article. The research topic addressed the application of LCA in the building procurement process. To gain better insights into the application of LCA in the tendering and awarding processes of public building projects, this article aimed to present the current state-of-the-art considerations of the LCA method in public procurement. For this purpose, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied to conduct an SLR. The research included a pre-selection and evaluation of current and qualified literature studies to answer two specific research questions:  
(i) \"Is LCA applied in the procurement processes of buildings?\"  
(ii) \"What is hindering the implementation of LCA in building procurement processes?\"  
While a few studies analyze the implementation of LCA in the construction procurement process based on real case studies and court cases [49; 50; 51], the novelty of our study lies in the comparison of this topic through a comprehensive literature review. Another uniqueness lies in identifying specific obstacles to LCA implementation that occur directly due to the implementation of LCA in the procurement process.
