Chemical processes form the basis for the existence of all living and inanimate matter. Moreover, the basis for the development of the material world and the determination of the objects’ and materials’ features belongs to the subject area of chemical processing. In this regard, the use of natural resources becomes an urgent problem in order to determine the possibility of its maximum conservation with more intensive use of it. For students of the Faculty of Chemistry, this is especially important since it is they who implement the processes of chemical production that cause the most significant harm to the ecological environment. In addition, the main task of ecologization is to minimize the damage received. Maintaining balance in this regard is the relevance of the research. The novelty of the research is determined by the fact that for the first time environmental competence is considered as a process of future professional support of work in the chemical industry. In the process of research, it was used the longitudinal method, which included a parallel experiment, in which participated the control and the experimental groups. The authors assume that environmental competence should be determined at the beginning of the work of each professional and influence them by applying specialized knowledge. The article reveals the methodological and essential characteristics of applying environmental competence in the professional training of senior students. The use of the proposed approach will allow the regional authorities to exercise operative control and model the scenarios for the development of the processes of ecologization of the territory due to the ecologization of education, taking into account the external environment changes.
