Eco-Labels, Trust, and Consumer Choice: An Empirical Examination of Sustainable Purchasing Decisions

Abstract

The present consumer behavior and corporate operating methods now prioritize environmental sustainability as their most important value. The combination of eco-labels and sustainability certifications serves as a vital resource for companies to show their environmental sustainability practices to customers who make purchasing decisions. The research study tests the hypothesis that eco-labels function as instruments that establish consumer trust and control shopping patterns within supermarket environments. The research study tests three factors, which include label transparency, consumer awareness, and brand credibility, to determine their effect on trustworthiness assessment and subsequent purchase behaviour. The researchers used structured questionnaires to collect data from 200 supermarket customers who lived in Thanjavur, Tamil Nadu, according to their study, which used Signalling Theory and Trust Theory as its research framework. The researchers used descriptive statistics, together with one-way ANOVA, correlation analysis, linear regression, K-means clustering, and hierarchical clustering to analyse the data. All demographic groups demonstrate high recognition of eco-labels, but this recognition fails to establish trustworthiness and brand credibility and customer loyalty. The researchers identified two distinct consumer groups: awareness-driven consumers who confidently use eco-labels and influence-driven consumers whose purchasing choices depend on social signals from others. The regression model showed that consumer satisfaction needs multiple elements which extend beyond credibility and buying patterns because these elements form separate dimensions that drive eco-label performance. The study adds to existing green marketing research by showing that effective certification systems that protect against greenwashing produce results that confirm their scientific validity.
