Proenvironmental Behavior Increases Subjective Well-Being: Evidence From an Experience-Sampling Study and a Randomized Experiment.

Two preregistered studies investigated whether engaging in proenvironmental behavior increases a person's well-being. A 10-day experience-sampling study (7,161 observations from 181 adults in 14 countries, primarily the United States) revealed positive within-person and between-person associations, and a randomized controlled experiment (N = 545 U.S. undergraduates) found that incorporating proenvironmental behavior into individuals' daily activities increased their experiences of happiness and meaning in life. Indeed, the effect was comparable to incorporating activities selected specifically to elicit such positive states, though these results may be affected by demand characteristics. The studies also offered some tentative preliminary evidence about why such an effect might emerge. There was some support for the hypothesis that proenvironmental behavior affects well-being by creating a "warm glow." But overall the findings align more closely with the hypothesis that proenvironmental behavior helps to satisfy individuals' basic psychological needs.
