Abstract: The object of research in this paper is the modern environmental policy of the European Union, while the subject of research is the relationship and mutual influence of the EU environmental policy in the context of the ongoing conflict of interests on this issue in various market segments. Also in this article, the authors tried to trace the dependencies of the mechanism of implementation of the environmental policy of the European Union, establishing what impact it has on the society of European countries and their economies, and what reverse impact these areas have on environmental policy. The "European Green Course" has become the central subject of research, since the effectiveness and mechanisms of its implementation at the pan-European and national levels reveal the essence of the modern environmental policy of the European Union. The authors identify the criteria for the formation of the EU environmental policy, as well as analyze the basic principles of the implementation of pan-European legislation on environmental policy. It is concluded that the environmental policy of the European Union has one interesting feature: it is one and different at the same time. The norms and rules of each specific country differ in their strength and target areas, while the result of the application of these norms, the targets, remain equal for all countries of the Union. The compactness factor of the European Union plays a significant role in shaping the principles of implementing and building a coherent environmental policy: any environmental incident has consequences for almost all EU member states, geographically the countries are located compactly, and the current relationship between the industrial concerns of EU countries makes them extremely sensitive to supply chain disruptions.
