The influence of Vietnamese consumers' altruistic values on their purchase of energy efficient appliances

Purpose - The purpose of this paper is to investigate how consumers' altruistic values influence their personal norms, environmental attitudes, subjective norms and perceived barriers, all of which in turn influence their pro-environmental behaviour (i.e. the purchase of energy efficient household appliances). Design/methodology/approach - This research follows a hypothetic-deductive approach. A unique conceptual model examines the role of consumers' altruistic values in relation to their environmentally responsible purchase behaviour. Structured questionnaires were administered to randomly selected Vietnamese consumers who visited busy electronics and appliance specialist stores, which yielded 682 usable responses. Findings - Structural equation modelling revealed that consumers' altruistic values tend to positively influence their personal norms, environmental attitudes, subjective norms and mitigate their perceived barriers in relation to the purchase of energy efficient appliances. Practical implications - Marketers, policymakers and sustainability campaigners should develop relevant communication and education programmes that emphasise the importance of purchasing energy efficient appliances for the environment and society, arousing consumers' sense of moral obligation and societal responsibility to purchase such products. They should also provide a convenient and easily accessible shopping environment for consumers. Originality/value - This research makes an important contribution by presenting and testing a new altruistic-values-based model that seeks to understand consumers' environmentally responsible purchase behaviour. This model could serve as a blueprint for future studies in the domain of pro-environmental behaviour, especially those in emerging markets.
