The authors of the paper proceed from the premise that environmental problems have long gone beyond national borders and have become an object of not only domestic, but also world politics. Despite the fact that a feature of this policy is the need for ever closer cooperation between states, integrating them into solving environmental problems, improving the mechanism of multilateral management of global environmental security, the United States and the EU countries are pursuing a tough sanctions policy against Russia. The paper examines the impact of economic sanctions on ensuring the environmental security of Russia. It is shown that the next block of problematic areas of the sanctions policy in relation to the country’s environmental security relates directly to the application of effective economic mechanisms for environmental protection and nature management. The authors substantiate specific proposals in the field of legal regulation of ensuring environmental safety in the context of economic sanctions. Among other things, it seems necessary to the authors to rethink the existence and benefits of countless new regulatory legal acts, the practice of adopting dozens of changes in existing environmental laws.
