Taking into account the current trends of globalization, digitalization, actualization of "green" innovations in the life of mankind, the educational policy of civilized countries is dominated by the problem of the cultural layer of the individual. In this regard, scientists are actively analyzing 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 of the phenomenon of "ecological consciousness". This made it possible, on the one hand, to comprehend the problem raised 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 behaviour); on the other hand, to detail the local history principle, taking as a basis the regional identity of the Ukrainian Danube, 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 conducted 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, is mainly studied within the framework of the subject specificity of cultural studies and pedagogy. Meanwhile, practitioners of higher education feel the need for a complete understanding of them, which is possible as a result of research into 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 options for 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 student social and environmental initiatives in intensifying the process of European integration.
