Promoting environmental sustainability: the influence of knowledge of eco-labels and altruism in the purchase of energy-efficient appliances

The purpose of this study is to extend the theory of planned behavior (TPB) and understand consumers' purchase intention of energy-efficient appliances (EEA) from the perspective of pro-environmental behavior. This study focuses on knowledge of eco-labels (KEL) and altruism for the consumers' purchase intention of EEA.

This study employed a quantitative method. Data of the participants were collected through the purposive sampling technique. A total of 373 valid responses were received with a response rate of 82.88%. Partial least square (SEM) has been used for the analysis of data.

The findings of the study reveal that altruism and KEL in the extended model of TPB promote the purchase of EEA in Pakistan. Further, the results indicate that altruism was the key predictor that leads to the consumption of environmentally friendly appliances.

Eco-labels are important sources that provide specific products related information to consumers. Further, eco-labeling serves to guide consumers' regarding the processes of products' consumption and disposals. Secondly, the positive influence of altruism implies the fact that people have the willingness to contribute to the betterment of the environment and human well-being. Therefore, marketers and policymakers should initiate campaigns that primarily target altruistic consumers and emphasize the importance of the purchase of EEAs that can reduce environmental pollution.

This study would help to understand consumer purchase intention for EEA and contribute to the literature of environmental management. The results of this study would serve to provide guidelines to policymakers and marketers regarding the consumption of environmentally friendly products (EFP).
