In recent years, the interest in research concerning Education for Sustainable Development (ESD) has grown considerably. Therefore, a thorough (re)evaluation of this field and its challenges is highly necessary and can help us better understand the diversity of ESD approaches and the ways in which various scholars, countries, institutions, or universities reacted through research and scientific publications to the study of ESD. Using a bibliometric approach, we analyzed 1813 papers on the subject, indexed by the Web of Science, between 1992 and 2018. The main findings increased our understanding of the ESD domain: we identified vital research, landmark studies in the development of the field, critical past contributions, emerging trends, and potentially transformative ideas. The number of publications, authors, and journals has increased, proving that ESD has gained momentum over the period examined in the study. Similarly, there are more and more works written in collaboration by people (scholars, researchers, etc.) from different parts and cultures of the world, indicating that publishing on ESD is like a legacy to international efforts to bring this area of inquiry into the mainstream. Finally, the study illustrates two main research directions for the entire timespan: integration of education into sustainable development and of sustainable development into education.
