Toward Sustainable Development and Consumption: The Role of the Green Promotion Mix in Driving Green Brand Equity and Green Purchase Intention

Consumers are becoming increasingly aware of the environmental and social consequences of their purchases. Research on the green promotion mix, green brand equity, and green purchase intentions has been fragmented. This study used the stimulus–organism–response framework to test the direct influence of green promotion tools on green brand equity dimensions and green purchase intention. A survey-based questionnaire was utilized to gather the data from participants who purchased milk products in Vietnam (n = 780). We analyzed the data using the partial least squares (PLS) method, a structural equation modeling (SEM) technique, with the assistance of SmartPLS computer program 3.0. The results reveal that green promotion tools have a significantly positive influence on green brand equity dimensions as well as green purchase intention. The results also reveal a relationship between green brand equity components, which is important for understanding corporate branding. The findings of this study provide valuable insights into how attitudes toward green advertising and sponsorship affect various elements of green brand equity, green purchase intention to generate and manage green brand equity, and green purchase intention.
