The research is devoted to the assessment of sustainability of activity of Russian largest corporations by market capitalization. Russian companies are beginning to declare their commitment to sustainable development, but the unified toolkit for evaluating their efforts has not been developed yet. It makes difficult to analyze the efficiency of the new business model, based on sustainable development concept. The proposed by the authors rating is based on the integrated indicator calculation, which combines a number of indicators reflecting different aspects of social, economic and environmental activities of companies. The paper offers the methodology for the formation of a sustainable development rating, which will propose an objective assessment of the weight of fundamental indicators characterizing sustainable business development. The developed methodology is applied to Russian companies but can be applicable for any business. © 2020 IEEE.
