The impact of global identity on the adhesion to pro-climate behaviours / <i>El impacto de la identidad global en la adhesión a las conductas pro-clima</i>

Climate change is a global problem that targets the whole planet, whose mitigation requires collective involvement. There is an ongoing joint effort between the governments of several countries that aims to devise policies and measures to mitigate each country’s impact on climate change. According to evidence, social identification, self and collective efficacy are relevant psychosocial processes that foster collective involvement in pro-ingroup behaviour. In this work, we test how two types of social identity (global and national identities) predict normative pro-climate behaviour when mediated by perceived individual and collective efficacy. In a correlational study ( N = 278), we found that global and national identities predict normative pro-climate behaviour to the extent that participants perceive collective efficacy, which did not occur with individual efficacy. We also found global identity to directly predict pro-climate behaviour. Results highlight the importance of the salience of national and, especially, global identities in predicting perceptions of collective actions’ efficacy and, thus, on climate change mitigation behaviour.
