An increasing number of people and organizations have become aware of global warming and environmental deterioration and have become engaged in socially responsible activities to save the Earth. However, a comprehensive model that integrates the antecedents, mediators, and moderators of green adoption is yet to be developed. In this study, a comprehensive research model was developed that incorporates a stimulus-organism-response (S-O-R) model, consumption value theory, and value–belief–norm theory. A quantitative approach was adopted to collect data from customers who had experience with green purchasing in Taiwan. The empirical findings reveal that the influence of green marketing activities on three mediators—consumers’ environmental attitude, consumption values, and personal norms—is significant. These three mediators have a significant impact on consumers’ innovative green adoption. Thus, a full meditation effect is found, suggesting that marketers should increase their focus on promoting innovative green adoption through environmental attitude, consumption values, and personal norms. The findings of this study may help academicians in conducting further theoretical validation and professionals in developing applicable marketing strategies to promote green adoption.
