Climate change and environmental pollution are urgent problems of today and survival of human species is at a stake. Companies have a great impact on the environment and consequently a responsibility. However, some companies use green marketing and public relations only to reach out to environmentally concerned consumers and generate profit without reducing their negative environmental impact. This unethical business practice is called greenwashing. It is a widespread practice with numerous negative consequences for companies, but also for the environment and a society. Research related to greenwashing is important so this practice can be easily detected but also more strictly regulated. The goal of this research was to point out the negative consequences of greenwashing on the image of the Nestlé company in Croatia and to deepen the discussion on the problem of greenwashing at the national level. A survey and a semi-structured interview were conducted. The main hypothesis of this paper is "Greenwashing negatively affects the image of Nestlé in Croatia" and it was partially confirmed. The conclusion is that greenwashing negatively effects the company’s image in Croatia among those respondents who believe that the company practices greenwashing. Namely, the level of awareness of greenwashing in Croatia is at a very low level, so most of the respondents do not know whether companies apply greenwashing. On the one hand, consumers in Croatia are not well educated or informed about this practice and on the other they neither are protected enough by law. The European Union has recognized the seriousness of the problem, so it has taken action to prohibit greenwashing. Whether the new laws will result in a reduction of this practice, strengthening the position of consumers and reducing the negative effects on the environment, we are yet to find out.
