The purpose of this study was to examine the association between sustainable consumption and life satisfaction. One aspect of sustainable consumption focused on in this study is the environment friendly purchase or green purchase. Using data collected from consumers in 14 cities in China, we found that consumers who reported green purchase intention and behavior had higher scores in life satisfaction compared to other consumers after controlling for gender, age, education, and family income. The findings add evidence to the literature that suggests happiness is associated with prosocial spending (Dunn et al., "Science" 319:1687-1688 in 2008).
