The author discusses in detail the findings of the first stagе of the study of library ecological movement prospects. The study was accomplished by Ecology and Sustainable Development Group of the Russian National Public Library for Science and Technology (RNPLS&T) in 2024. The author describes the survey structure and explores the feedback. The obtained information enabled to develop the profile of libraries engaged in ecological education, to identify the most popular approaches to environmental knowledge popularization, and to accumulate librarians’ views on ecological movement and its conceivable prospects. Respondents emphasized the need for complex theoretical and practical developments to engage child readers, importance of ecological local studies as the key activity, and the need for methodological support and partnership. The survey also reveals the contradiction between desirable and real situations in audience targeting in ecological education, and movement coverage in digital space. The author points to the differences in the green library conceptualization between Russian and foreign librarians and re searchers. Based on the first stage findings, she concludes that the terms have to be refined and unified, while the methodological aids have to be developed in the con text of Russian library practice. The second stage questionnaire will focus on the library contribution to the RF national development goals, green librarianship terminology, and possibilities for the libraries in the era of digital transformation.
