Understanding the relationship between happiness and positive factors and pro-environmental behavior offers important practical implications for sustainable social development. To investigate the positive antecedents of pro-environmental behavior, the current study focused on psychological richness and examined its influence on pro-environmental behavior as well as potential mechanisms and boundary conditions through 10 studies (N = 2979). It is shown that psychological richness facilitates engagement in sustainable activities (Studies 1.1-1.4) through an increased level of self-expansion (Studies 2.1-2.4). Furthermore, the effect of self-expansion on pro-environmental behavior was more significant when individuals viewed nature as smaller than themselves (Studies 3.1-3.2). These findings reveal the positive effect of happiness on pro-environmental behaviors and provide insights to promote people's participation in building a sustainable society.

Key words: psychological richness, self-expansion, self-nature size, pro-environmental behavior
