The value of environmental self-identity

Social Psychology

To overcome environmental problems we need to know what important antecedents of environmental behaviour are. Environmental self-identity can be defined as the extent to which you see yourself as an environmentally-friendly person. We found that it is indeed related to a range of pro-environmental actions, for example, energy use and preference for sustainable products. We found that environmental self-identity is partly stable, as it is influenced by one’s biospheric values. Biospheric values even predicted environmental self-identity at a later moment in time and after a manipulation of environmental self-identity. However, environmental self-identity can also be changed to a certain extent. Based on self-perception theory we studied whether reminding people of their past behaviour influences their environmental self-identity. We indeed found that when people realize that they often acted environmentally-friendly in the past their environmental self-identity was strengthened which in turn promoted pro-environmental actions. When people realized they rarely acted environmentally-friendly in the past their environmental self-identity was weakened and they were less likely to act pro-environmental. However, past behaviour only influenced environmental self-identity when the signalling strength of the past behaviour was high. Only

Main project

This project is part of project "Spill-over of initial pro-environmental actions to other pro-environmental behaviours".
