In recent years, environmental concerns, the changing mindset of society, and the adoption of sustainability in life have offered scope to business houses for more opportunities to implement green advertisement. Green advertisement refers to promotion with an eco-ecological theme or emphasizing the ecological aspect of a product or CSR initiative implemented by an organization. Although its growth over the last three decades is impressive, green advertising has yet to reach its full potential in influencing consumer behavior comprehensively. This paper focuses on the role of green advertising in changing environmentally friendly consumption decisions. This study will assess the correlation between green advertising, the green brand image, and customer awareness about eco-friendly products. This research utilized a mixed-methods approach by using surveys and case studies to evaluate the effectiveness of green advertising in shaping consumer attitudes and purchasing behavior. The findings reveal that green advertising is a strategy that not only enhances green brand perception but also raises consumer awareness of environment-related issues. Presenting effective communication strategies, such as emphasizing the usage of natural resources and CSR activities, can help companies to have an impact on consumer attitudes and promote sustainable consumption choices. Further, the study underscores the use of green advertising as an effective tool that promotes environmental awareness and leading change in consumer behavior toward ‘green’ products. The study will provide Businesses a practical input that shapes workable ideas for their campaigns so that business will refine their advertising strategy and contribute meaningfully movement toward global sustainability.
