This book is a comprehensive economic and legal study of the theoretical and practical aspects of the problems of increasing energy efficiency; self-motivation of energy saving by business entities within the framework of their corporate responsibility; regulatory mechanisms to stimulate energy conservation in the economy; civil-law regulation of foreign trade turnover of energy resources between economic entities of the Russian Federation and companies of member states of international integration associations - the CIS, EEMP, the EU and BRICS. It argues that technological energy saving plays a key role in reducing the energy intensity and increasing the energy efficiency of the economy, and substantiates the need for institutional support - including legal support for the participation of the Russian Federation - in various forms of international cooperation.
