Abstract
Climate change mandates us to understand why individuals do (not) behave pro‐environmentally and personality traits are well suited for this purpose. Past research has mostly focused on how broad domain‐level personality traits were associated with pro‐environmental attitudes and behaviors. In two datasets (N = 501 and 287), we examined whether personality facets provided a more detailed picture of how personality traits were associated with pro‐environmental attitudes and behaviors. It was found that some facets were the main drivers of domain‐level associations. Furthermore, it was found that facets, collectively, predicted pro‐environmental attitudes (r = .50 to .52) and behaviors (r = .29 to .42) in holdout datasets. This predictive ability was on par with the predictive ability of domains. Therefore, facets provided a greater understanding of how personality traits were associated with pro‐environmental attitudes and behaviors. Furthermore, facets provided a similar predictive ability of pro‐environmental attitudes and behaviors to that of domains.
