Consumers' purchasing decisions are influenced by various factors, including green marketing strategies, brand image, and environmentally conscious behaviour. This study aims to analyze the influence of green marketing strategies, brand image, and environmental behaviour on the purchase decision of Le Minerale products. In addition, this research also aims to increase consumer awareness of the importance of ecological protection, and companies are increasingly using sustainable marketing techniques to attract consumers' attention. The methodology of this study uses a quantitative approach, using data collected through questionnaires distributed to Le Minerale consumers at MAN 3 Ngawi with a total of 124 students. Data analysis was carried out using multiple linear regression. The results of the study show that green marketing strategies have a significant influence on the purchase decision of le minerale products, with a sig value of 0.040<0.050, brand image has a significant influence on the purchase decision of le minerale products, with a sig value of 0.002<0.05, and environmental behavior has a significant influence on the purchase decision of le minerale products, with a sig value of 0.026<0.05. These findings provide theoretical implications that the adoption of green marketing strategies not only improves brand image, but also encourages more environmentally responsible consumer behavior. This research contributes to the green marketing literature as well as inspires other companies to integrate sustainability values into their marketing strategies.
