Existing consumption patterns of goods and services and declining resilience of natural resources greatly reduce the ability of future generations to meet their needs. The relevance of the concept of sustainable development is established. However, its diverse interpretations depend on the parties involved in the process, which has to some extent contributed to the transformation of the meaning of the concept of sustainable development into a concept that many talk about, but only a few understand its importance for the survival of civilization in the face of the impending natural and social disasters that future generations will face. The paper uses a systemic approach to identify critical points in the concept of sustainable development, such as current consumption patterns, resilience of natural resources, market participants’ behaviour, satisfactory groups current needs, disposable income levels, different levels of governance and planning documents, the number of future consumers, their habits and various uncertainties. Based on the shortcomings of the concept of sustainable development, the authors present their model of sustainable development system, which complements the idealized three- (economic, social and environmental) dimension model with technical and governance dimensions and takes into account the factors influencing sustainable development of the country.
