Green marketing has been a main topic of discussion for several years. Most studies conducted in this area have focused on the benefits of green marketing for a normal company. However, no studies have considered the effectiveness of green marketing by a negative brand like BP. This study aims to reveal the effectiveness of green marketing after pollution. An experiment was conducted to evaluate participants’ attitudes toward the marketing strategy. Although the results were not significant, some interesting findings were revealed and are addressed at the end of the paper. They imply that individuals with green awareness are less influenced by both green marketing and an economic-assistance strategy in BP’s case, compared to individuals with lower green awareness. Overall, all participants in this study preferred the economic-assistance strategy, which means that green marketing is not effective for a corporation involved in pollution issues. / text
