This survey has been conducted toward 456 respondents. This study utilized nonprobability sampling by purposive sampling. Smart PLS 3 software used for structural equation modeling This approach allows for the collection of extensive data on consumer behavior and sentiments. The results reveal that Attitude, Subjective Norms, and Perceived Behavioral Control have a significant and positive impact on consumers' intentions to purchase eco-friendly products. Additionally, green advertising and eco-labeling play a crucial role in shaping actual buying behavior toward such products. The intention to purchase also significantly drives environmentally conscious buying behavior. However, green branding does not exhibit a positive influence on consumer purchasing decisions. This suggests that consumers are more likely to develop purchase intentions when companies effectively communicate their environmental commitment.
