Nowadays environmental protection is one of the most pressing global topics that appears in more and more corporate promotions. The expansion of the Internet and the rise of the digital world and social media have opened up new opportunities for companies to carry out green promotional activities. The purpose of the study is to examine the attitude of consumers in the online space towards the promotion of companies related to environmental protection and to propose different strategies in this regard. In this article, using netnographic research method, the comments received under the environmental protection related Facebook posts of the top 12 Hungarian FMCG (Fast-Moving Consumer Goods) companies are analyzed and users are segmented, based on their attitude and reactions. Three main groups (supporters, critics, objectives) and eight subgroups can be distinguished (idealists, humorists, interested, helpless, experienced, smartass, informants and whishers) in the case of companies' Facebook posts related to the environment. Critics can generate negative eWom, while supporters can generate positive online word of mouth for the company. Finally, regarding the treatment of different segmented groups, we formulate online and offline strategies that companies should follow. It is recommended for companies to continuously monitor and analyze online comments, since with the help of feedback they can improve their operational activities and avoid image damage caused by negative word of mouth.
