Recent developments in the social identity approach to the psychology of climate change.

We review recent literature on the social psychology of climate change, focusing on the application of social identity theory and self-categorization theory. These two theories, together forming the social identity approach, point to ways in which collective identities influence responses to climate change. Recent research demonstrates that collective identities influence attitudes, beliefs and behavior relevant to climate change, and they do this through processes such as group norms and social influence, collective efficacy, and collective emotions. The SIA suggests that, in general, people are motivated to protect the identity and status of their ingroups. Indeed, recent studies find that groups who are of higher status, and thus have more to gain from protecting the status quo, tend to be less concerned about addressing climate change than lower status groups, who are more likely to be harmed by climate change. However, individuals from both high and low status groups will be more likely to work towards pro-environmental social change when they perceive current social systems that perpetuate climate change as illegitimate and when they can imagine cognitive alternatives to the status quo, where humans have a more sustainable relationship with nature.
