Aim. To develop a justification of the structure of the institutional model for the formation of environmental culture of young people as a holistic structure that integrates the various actors in this process, as well as the available resources and implemented technologies to achieve the aims of sustainable regional development.Material and Methods. The empirical justification of the proposed model was based on 14 focus group interviews conducted in the Krasnodar region in 2022 with representatives of young people, expert sessions with representatives of institutional structures involved in the implementation of practices to form the ecological culture of young people (12 expert sessions), online questioning of young people (sample size 1600 respondents). The case-study method was used to analyse eco-oriented practices in the field of youth and educational policy.Results. The authors identified and characterised the main subjects involved in the formation of the ecological culture of young people, the set of technologies used (information and communication, game and project) and the resources and principles that determine the effectiveness of environmental education and educational practices. The authors propose a structure of the institutional model of the process and the results of formation and development of youth ecological culture, revealing its cognitive, value, emotional and activity components in the context of sustainable regional development.Conclusion. The universal nature of the structure of the proposed model allows us to extrapolate the main results in the system of pedagogical support of the development of youth ecological culture in the activities of educational providers, as well as creating a basis for their institutionalisation in the activities of the executive authorities and bodies working with young people, not only in the Krasnodar Territory but also in other regions of the Russian Federation.
