Abstract: This study explores the impact of green marketing strategies on consumer loyalty, examining the extent to which environmentally responsible branding influences customer retention and advocacy. With increasing environmental awareness among consumers, businesses are leveraging green marketing to differentiate themselves and build stronger emotional connections with their target audiences. Through a mixed-methods approach, including surveys and case studies, this research investigates how green marketing initiatives—such as eco-friendly packaging, sustainable sourcing, and transparent environmental claims—affect consumer perceptions, trust, and long-term brand loyalty. The findings indicate a positive correlation between the authenticity of green marketing efforts and consumer loyalty, particularly among environmentally conscious demographic segments. The study concludes that while green marketing can be a powerful driver of loyalty, its effectiveness hinges on perceived credibility and the alignment between a company’s environmental claims and its actual practices.
