For over twenty years, the libraries’ contribution to ecological education has been being reflected in the professional program of Crimea World Forum within the section “Ecological information and ecological culture”. In 2018, the section transformed into the conference on ecological education though kept its original name. The Russian National Public Library for Science and Technology (RNPLS&T) and V. I. Vernadsky Non-governmental Ecological Foundation permanently co-organize the Conference. The author reviews the conference events, as well as problems and tasks discussed at the Conference; includes the abstracts of papers delivered (the full texts are accessible via the RNPLS&T’s website). The participants in the Conference agreed that the libraries had to adopt the integrated approach toward the UN Sustainable Development Goals (SDGs) and to see themselves participating in the global movement for stable and sustainable future. For this purpose the libraries possess every resource: the books embrace the best experience of the humankind; the professionals who are able to retrieve these books and to offer them to their patrons, and to orient themselves in information flows. The true goal of the Conference is to promote the SDGs more so as the Russian libraries are traditionally serious about ecological education.
