The current research examines the extent to which attitudes and personality traits are predictive of pro-environmental behavior (PEB). Concretely, we tested the relationship between pro-environmental attitudes, HEXACO personality traits, and actual PEB (donating potential prize money to a pro-environmental organization; N = 257). Additionally, we controlled for the influence of helping behavior (donating to a pro-social organization) by addressing whether attitudes and personality have a distinct impact on PEB or whether people are more likely to engage in PEB because they act more pro-socially in general. Analyses included correlations, multiple linear regressions, mediations, and partial correlations. Pro-environmental attitude had the most robust association with PEB and mediated the influence of openness to experiences and honesty–humility on PEB. Importantly, the relationship of pro-environmental attitudes and personality (openness to experiences and honesty–humility) with PEB was unaffected by the participant’s helping behavior, suggesting that pro-environmental people mainly care about the environment and are not necessarily more pro-social in general.
