Enhancing consumers' pro-environmental purchase intentions: the moderating role of environmental concern

Purpose Environmental concern is getting increasing importance in consumer shopping decisions. Nevertheless, to date, sustainable packaged foods are not always the first option when consumers go shopping. This paper analyses how environmental concern moderates the role played by external factors - preference towards sustainable retailers and trust in sustainable producers - in determining consumer purchase intentions for sustainable packaged foods. Consumer involvement in eco-friendly labels, increasingly present in food packages, is investigated as indirectly impacting pro-environmental purchase intentions. Design/methodology/approach An online survey administered to a sample of Italian food shoppers is used for the empirical analysis. A total of 278 structured questionnaires were modelled using a structural equation modelling approach. Findings Findings show that producers and retailers' policies in favour of sustainability are key in determining consumers' sustainable purchase intentions. Further, coherent uses of labels and logos in light of sustainability can support consumer purchase decisions. Relevant is the influence played by the environmental concern in both supporting pro-environmental purchase intentions and in amplifying the trust in sustainable producers-purchase intentions path. Originality/value This study contributes to the literature on sustainability showing how producers and retailers may together influence consumers' pro-environmental purchase intentions. Findings extend the retail literature on the impact of producers and retailers' policies on consumers' sustainable purchases. Further, environmental concern is investigated in its moderating role on the impact of external factors on consumers' pro-environmental purchase intentions.
