Introduction. Social and hostility conflicts in Ukraine have caused global changes and deterioration of the ecological and economic situation in numerous countries, resulting in higher risks to the population and giving the impetus to create a new innovative, cultural, and technological society. Greening principles, which have become popular in developed countries, are impossible to implement without the coordinated cooperation of states and their genesis in accordance with joint programs and development vectors. As a result, an increasing number of foundations and grants have recently been established to support eco-friendly products and solutions, assist in their adoption, and develop the organizational structure of an efficient system based on green economy principles, thereby improving global standards and regulations. Aim and tasks. The aim of the study is to develop a methodology for planning the modernization of constructed infrastructure, better resource efficiency, and reduce waste in the reconstruction of war-destroyed objects. Results. The best option for post-war waste disposal is the construction of mobile waste recycling complexes based on fractional waste recycling and its secondary use in further reconstruction of Ukrainian infrastructure, which after final restoration will be moved to safe areas around large cities and used as stationary waste recycling plants. To improve the environmental situation, one suggests building landscaped parks that will operate due to state-of-the-art technologies (obtaining natural energy, etc.) and creating a system of harmonious combination of anthropogenic infrastructure and natural areas, businesses, and public accessibility. Conclusions. The key goal of the reconstruction of Ukrainian territories is to establish an innovative, sustainable, and safe system of social existence by increasing the efficiency of actions and methods based on the principles of rational environmental management and increasing responsibility. When calculating the cost of the restoration of Ukrainian territories, one should take into account additional expenses caused by hostilities, which will be further considered as a stress factor having a cumulative negative impact and leading to disastrous consequences that can be estimated in monetary equivalent as the sum of the price of restoration of components of the ecological, economic, and social system under the effect of a set of factors resulting in negative changes and damages.
