This study examines the impact of green marketing on the green purchase intention of consumers in Vietnam. We developed a research framework with five independent variables including green product, green price, green promotion, green place, and green marketing awareness, and test their relationship with green purchase intention. Convenient and snowball sampling methods were employed to collect data. A self-administered online survey was conducted from March to May 2022. We collected 265 valid responses in 3 months. SPSS 22 software was employed to run the regression analysis. Our findings show that green promotion was the most essential dimension in the green marketing mix that affects the purchase intention of the consumers, followed by green place and green product. There was not enough statistical evidence to confirm the negative impact of green price on the purchase intention of Vietnamese consumers in this study. Based on the findings, it is suggested that marketers alter their marketing mix strategies to respond to consumers’ rising demand for green products.
