Perceived economic inequality inhibits pro‐environmental engagement.

We currently inhabit an era marked by increasing economic inequality. This paper delves into the repercussions of perceived economic inequality on individual‐level pro‐environmental engagement and puts forth an explanatory mechanism. Across three empirical studies encompassing an archival investigation employing a nationally representative data set (Study 1), an online survey (Study 2) and an in‐lab experiment (Study 3), we consistently unearth the inhibiting effect of perceived economic inequality on individuals' pro‐environmental involvement, whether assessed through pro‐environmental intentions or behaviours. Furthermore, our findings reveal that individuals' identification with their country elucidates these results. Specifically, perceived economic inequality diminishes individuals' national identification, encompassing their concern for the country's well‐being and their sense of shared destiny with fellow citizens, thereby curbing their pro‐environmental engagement. Additionally, we conduct a single‐paper meta‐analysis (Study 4), revealing small to moderate effect sizes for our key findings. Theoretical and practical implications stemming from these novel findings are discussed. [ABSTRACT FROM AUTHOR]
