Taking into account the modern tendencies of globalization, digitalization, actualization of "green" innovations in the life of mankind, the problem of the cultural layer of the individual dominates in the educational policy of civilized countries. In this regard, scientists actively analyze the leading factors, in particular, the process of formation of the ecological culture of the younger generation. Researchers have already assessed the advantages of a value-based psychological approach that determines the understanding of the role of environmental consciousness in the development of an individual's eco-culture, as well as a structural-component representation about the phenomenon of "ecological consciousness". This made it possible, on the one hand, to comprehend the raised problem from the point of view of the ecological culture of the individual in the period of mature adolescence, where the key is environmental consciousness (a fusion of environmental knowledge, assessment of the environmental situation, environmental behavior); on the other hand, to detail the local history principle, taking as a basis the regional identity of the Ukrainian Danube Region, which is associated with the Danube River, its transboundary role in the formation of the ecological consciousness of the student youth of the united Europe.

The held psychological discourse made it possible to establish that the content of the development of the ecological culture of the individual and its parameter – ecological etiquette, are mainly investigated within the framework of the subject specifics of cultural studies and pedagogy. Meanwhile, practitioners of higher education feel the need for a complete understanding of them, which is possible in a result of research of the specifics of the psychological support of these processes. This was the purpose of our study, and its main methods were: a thematic questionnaire, including two variants of closed questions – self-evaluative judgments of the respondent regarding the degree of manifestation of environmental etiquette and awareness of the problems of the Danube ecology, the role of students’ social and environmental initiatives in intensifying the process of the European integration; method “ESOP” developed by V.A. Yasvin, which allows to establish the student's dominant attitude concerning a real relationship to nature.The uniqueness of our study lies in the study and reflection in this article of the nature of the psychological support for the development of environmental etiquette of Ukrainian students (where the basis is the European integration role of the Danube River).
