ABSTRACT
Most of us have come into contact with environmental activism in some form, such as seeing news coverage of environmental protests and activists such as Greta Thunberg, or participated in protests to fight or raise awareness of the climate crisis. Even though the former may leave us unaffected, the latter, participation in environmental activism, can have a profound effect on our lives. In this chapter, we outline and discuss the range of biographical changes, such as changes in consumption behaviors and increased well-being, that may emerge during environmental activism and activism in general. We develop a theory of self and self-change with its foundation in four identity dimensions (content, boundaries, legitimacy, power) and suggest relations within the group and with other groups as processes for environmental biographical consequences to emerge. We highlight the importance of perceived supportive interactions and relationships with other environmental activists for the biographical consequences to endure.
