The paper identifies the main features of environmental responsibility of enterprises of the metallurgical industry based on the analysis of the evolution of the concept of environmental responsibility of metallurgical enterprises, as well as the analysis of the etymology of the term "environmental responsibility of an industrial enterprise". On the basis of the conducted research of existing methods of environmental responsibility assessment, their main shortcomings were revealed: the relative complexity in their application, the availability of a basis of the research that is not available to a wide range of information, the presence of some subjectivity (including, in determining the weights ). With a view to eliminating them, a methodology for assessing environmental responsibility has been developed, characterized primarily by a statistical approach to determining weights of indicators (the method of pairing preferences), and by determining the relationship between the level of environmental responsibility and the level of economic development. The developed methodology was tested on the data of social reporting of the largest metallurgical enterprises. Namely: Norilsk Nickel and Severstal. The data presented in the reporting for the period 2012-2016 were investigated. The results of the study made it possible to determine that the level of environmental responsibility and the level of economic development of the enterprises under study is low. The results of the correlation analysis of the two integral indicators: economic development and environmental responsibility made it possible to conclude that there is a close relationship between the enterprise of Norilsk Nickel and the Severstal's tendency towards a weak inverse relationship, but to unambiguously confirm this trend You need a larger data set.
