Today, more so than ever before, companies are a part of a wider network of relationship and need legitimacy to operate in an increasingly global competition market. The growing attention of the world on ethical, environmental and social issues, has recently prompted companies to draw up their own annual Activity and Corporate Responsibility Report in order to create added value for their stakeholders and be successful. The purpose of this article is to analyze and compare the corporate social responsibility policies adopted by eight major retailers listed in the global retailers’ ranking of Deloitte, using a conceptual model composed of four fields of action: 1) company, 2) products and assortments, 3) social commitment, and 4) environmental commitment. The comparative analysis highlights some differences between retailers from different countries of origin and suggests new research perspectives.
