Environmental Education has become over recent decades an emerging area of knowledge; its evolution has been conditioned not only by different regional dynamics, but also by international guidelines and trends. Therefore, the literature reports multiple and diverse pedagogical, curricular and transdisciplinary approaches to this topic. Likewise, studies on the dynamics and trends in the generation and production of knowledge are relevant to both teachers and researchers in every field of knowledge. In this sense, it is presented a bibliometric study that aims to analyse the international scientific production on Environmental Education on the Web of Science (WoS) within the categories Education and Educational Research and Education, Scientific Disciplines for the last two decades (2000-2019). The information obtained was analysed using different bibliometric techniques, like descriptive statistics, degree of collaboration and co-occurrence maps generated by VOSviewer (version 1.6.15) software. The results show the accelerated increase in the production of knowledge in this area, they present the main research contexts, as well as some educational and research perspectives. Also, the collaboration between authors and universities was identified. Keywords: bibliometrics analysis, environmental education, scientific education, scientific production
