Topicality. The problem of anthropogenic impact reducing on atmospheric air is especially relevant to date. Ukraine ranks one of the first places in the world of mortality rate from environmental pollution and one of the main sources of pollution is the operation of coal installations.Most of the equipment of the large power plants of Ukraine is in the pre-critical state, it is morally and physically obsolete. Unsatisfactory condition of environmental technologies and non-compliance with international requirements of the cleaning of atmospheric air emissions from the thermal power plants are the urgent issues of the current international economic and environmental policy of the country. Aim and tasks are to determine the prospects of introducing and improving the environmental management system at Large Combustion Plants in Ukraine in the context of the National Plan for Reducing Emissions to reduce the environmental risks posed by pollutant emissions from heat power plants and the entry of Ukraine into the international stage in the field of ecology and energy. Research results. The article examines the main environmental risks caused by the operation of heat energy facilities and international requirements that Ukraine must fulfill in the near future. Also reviewed are the possible risks faced by the objects of heat power in the path of environmentalization.Based on the research, implementation of the ecological management system at Large Combustion Plants of Ukraine in the context of the National Plan for Reducing Emissions is proposed in order to reduce the potential risks of environmentalization and rational use of the resource potential of heat power sector enterprises. The possible ways of introducing the ecological management system and the impact of such modernization of heat power engineering objects on the international status of Ukraine as a country that has joined the international initiatives are determined. An example of a successful introduction of the environmental management system at the heat energy project of Ukraine related to large combustion plants and its compliance with the requirements of the National Plan for Reducing Emissions is given.Conclusions. The introduction of the environmental management system will enable heat energy facilities to rapidly and rationally transition to new technologies, fulfill international requirements and, in turn, reduce to a minimum the risks associated with atmospheric air pollution.
