The article is devoted to the study of the state environmental security in national and globalization aspects. It has been established that the environmental security of the state is a status of every person’s security, society, state and nature from excessive danger to the environment, i.e. the preservation and protection of vital activity, individual’s interests and his environment from negative anthropogenic and natural consequences, which is an important component of the state security. It is established that together with the concept of “environmental security” there is a concept of “environmental modernization” as overcoming of negative impacts on environment from the industrial society by transformation of the latter with help of the latest technologies. The existing threats to Ukraine’s environmental security, identified in the National Security Strategy of Ukraine in 2015 have been determined. The need for additional attention to the armed conflict in eastern Ukraine was emphasized as one of the threats to the states’s economic security, which is in line with the provisions of the United Nations Resolution “Environmental Protection in Areas Affected by Armed Conflict”. It is noted that the Ministry of Ecology and Natural Resources only formally fulfills the task of assessing the environmental status, unlike Finland and Sweden. The issue of public participation of Ukraine in environmental management is still debatable, as defined by the Law of Ukraine “On Environmental Protection”, it remains only formal, although, for example, the public is actively involved in the management of this field in China. Accordingly, it was proposed not only compliting tasks by the Ministry of Ecology and Natural Resources to develop a single list of indicators at EU level for assessing the environment status, but also to involve the public in full participation in environmental management.
