The aim of this research was to identify the current trends and tools in the field of real estate sustainability assessment and to determine their relevance for real estate valuation. Bibliometric analysis, an in-depth search of Web of Science sources and a co-occurrence or cluster analysis were used to meet the objective. From the research, it was found that LEED and BREEAM certifications are the most widely used among the current trends and tools in real estate sustainability assessment. Sustainability itself shows relationships with property valuation, but these are not strong, and therefore it can be assumed that, currently, sustainable properties do not have the concept of valuation itself, nor is this topic the main focus of the research. On the positive side, there is potential for sustainability in real estate valuation issues, where sustainability certifications are expected to play an increasingly important role in the real estate valuation process in the future. A limitation of the research is the fact that many publications do not directly address the sustainable property valuation process, but this is a potential for a new research direction that would specifically address the sustainable property valuation process.
