The implementation of the sustainable development agenda is driving growing interest in the formation and disclosure of ESG data in companies» non-financial reporting. Currently, reporting in the field of sustainable development in the Russian Federation is at the stage of development, but already has many years of experience in the formation of estimated values and the application of Global Reporting Initiative (GRI) standards. This article analyzes the dynamics of non-financial reporting of Russian companies and identifies the main trends in its development. A content analysis of non-financial reporting items was carried out using a score in the context of ESG components: environmental, economic and social. The results of the study, on the one hand, allow us to conclude that the reporting indicators of leading companies in the field of sustainable development are highly complete, clear and reliable, but, on the other hand, they indicate low comparability of the reporting indicators of different economic entities. The lack of uniform approaches and standards for developing the structure and composition of non-financial reporting indicators is the main obstacle to its interpretation by various groups of stakeholders.
