This study investigates the impact of green brand affect on green purchase intentions and explores the mediation effects of green brand attitude and green brand associations by means of the structural equation model (SEM). There is no previous literature discussing the relationship between brand affect and purchase intentions from the perspective of green marketing. Therefore, this article establishes a green purchase intention framework to fill in the research gap. The research object of this study focuses on Taiwanese consumers who have the purchase experience of information and electronics products in Taiwan. A total of 1000 consumers were randomly selected and 365 valid responses were received. In addition, this research conducted an empirical study using a questionnaire survey and structural equation model (SEM) to verify the research framework. The results show that green brand affect has no direct influence on green purchase intentions. Besides, this study indicates that green brand associations and green brand attitude fully mediate the relationship between green brand affect and green purchase intentions. It implies that green brand affect indirectly influences green purchase intentions via green brand attitude and green brand associations. While companies tend to raise their customers' green purchase intentions, they need to increase their green brand affect, green brand associations, and green brand attitude.
