Research methods: observation; description; analysis and synthesis; logic; comparison. Research methodology: consideration of the theoretical principles of the taxation system with a negative impact on the environment; identification of the interrelationships of the elements of this system and the violation of interrelations; formation of theoretical conclusions for national interests based on the study of taxation practice.
The main conclusions of the study are: 1) all the countries under study apply tax instruments aimed to reduce the negative impact on the environment, the specifics of the taxation systems are determined by the specifics of the resource potential and historical aspects; 2) the regime of cross-border carbon regulation is a form of struggle for the competitive advantages of European companies. The novelty of the study is: 1) the priority importance of the taxation system with regard to the environment, which has a cross-border and transnational character, is revealed; 2) the need to stimulate the introduction of technologies aimed at reducing greenhouse gas emissions and other harmful substances is proved; 3) the features of the implementation of the mechanism of cross-border carbon regulation in the Russian Federation in the current economic conditions are outlined.
