As a massive corporation it is almost impossible to keep your reputation clean due to the scale of its production. And Carrefour has not been an exception. The eighth-largest retailer in the world by revenue has had its fair share of accusations, scandals and lawsuits. To overcome their past and advance to the next level Carrefour needed to start from the bottom again and to build a new and more positive corporate image. That's where Corporate Identity Programming comes in. As one of the main functions of Public Relations Corporate Identity Programming is responsible for the enhancement and protection of a company's reputation. And with the help of the corporate identity program “Act for Food” Carrefour managed not only to change their image for the better but also to make a change in the world.
