The authors examine the current state of environmental marketing and environmental product in Russia in terms of legislation and market practices; analyze the evolution of these concepts in foreign and Russian publications; systematize experience in this field; provide an original conceptualization of these terms; operationalize their key characteristics and features.Methods. This study is based on qualitative empirical research using such methods as content analysis, synthesis, formalization, and systematization. The theoretical and methodological approach of the study is based on the works of foreign and Russian scientists in the field of environmental marketing, the “green” approach to the promotion of goods, and sustainable enterprise development.Results. A research gap in the conceptualization of “environmental marketing” and “environmental product” in Russian language is identified. The authors provide an original interpretation of these concepts with allowance for the principles of sustainable development and “green” promotion.Conclusions. This study serves to elaborate on the scientific meaning of the concept of “environmental friendliness” applicable in marketing, changing the trend of the increasing number of products that fall under the definition of greenwashing. The published materials can be useful for environmental consultants, marketers, and representatives of legislative authorities in certifying products according to environmental standards.
