Greenwashing, the practice of brands making false or exaggerated environmental claims, has become a major concern across industries, especially in the food, fashion, and beauty sectors, as consumer demand for sustainable and ethically made goods rises. This study examines how consumers react to greenwashing, with a particular emphasis on their awareness, attitudes, and behaviors in the face of false sustainability promises. This study investigates how consumers recognize and interpret greenwashing, the emotional and cognitive elements affecting their reactions, and the actions they take in response—such as boycotting brands or looking for more transparent alternatives—by analyzing consumer surveys and existing literature. The paper also delves into the role of brand trust, social media, and regulations in shaping consumer reactions to greenwashing. Results indicate that although consumers are become more conscious of greenwashing, there is still a sizable gap in their capacity to recognize false claims. The study emphasizes how crucial third-party certification, brand openness, and consumer education are to reducing the damaging effects of greenwashing. In the end, the study urges consumers and brands to take a more proactive and knowledgeable stance inorder to guarantee that sustainability initiatives are sincere and significant.
