Consumers’ low awareness and negative attributions remain critical impediments to companies’ attempts to reap the potential benefits of CSR. Addressing the gap of how and under which conditions what type of attributions arise and the role of stakeholder factors in CSR communication strategies, the aim of this chapter is to assess to what extent national culture influences the attributions that arise towards green advertising. Preceded by a pre-test, a survey was conducted in Colombia, The Netherlands and USA. With a total of 248 responses, a multiple regression analysis was performed to analyze the data. Results show main effects of national culture on the attribution of negative motives. Specifically, the cultural dimensions power distance and uncertainty avoidance have a negative effect on negative attributions. On the other hand, results indicated that positive attributions are not influenced by national culture. The research stresses the relevance of national culture as a stakeholder-factor, influencing the effectiveness of green advertising.
