Predicting green product consumption using theory of planned behavior and reasoned action
The extended Theory of Planned Behavior (TPB) incorporates environmental concern, a critical variable in green marketing literature, intending to achieve triple bottom line (TBL) In this context, this study aims to validate TPB and its extended form (mediating role of TPB variables) as well as the Theory of Reasoned Action (TRA) to predict Indian consumersaEUR(tm) green product purchase intention. We collected primary data from 521 respondents as input, establishing validity through confirmatory factor analysis (CFA) Our empirical results of structural equation modeling (SEM) show that extended TPB has higher predictability than TPB and TRA in green marketing settings. Consumer attitude and perceived behavioral control significantly predicts purchase intention whereas subjective norm does not. Our findings also suggest that TPB mediates the relationship between environmental concern and green products purchase intention. An additional construct in the new model considerably contributes to improving the understanding of green products purchase intention formation and could become a sustainable mainstream variable.
