The effect of income satisfaction on the relationship between income class and pro-environment behavior

This study investigates the linkage from income class to pro-environmental behaviour among people with different income levels. By setting a hierarchical regression model and using data from the World Value Survey (WVS), this study finds that higher income reinforces pro-environmental behaviour. In addition, income satisfaction significantly strengthen the relationship between income class and pro-environmental behaviour, such that the link between them gets stronger when the individuals are satisfied with their income. The findings show that income level and income satisfaction go hand-in-hand in bringing about pro-environmental engagement.
