Action speaks louder than words: The effect of personal attitudes and family norms on adolescents’ pro-environmental behaviour

Adolescents’ environmentally relevant behaviour is primarily carried out in a family context. Yet, it is usually studied and discussed in an individual decision-making perspective only. In a survey involving 601 Danish families, we examine to which extent adolescents’ everyday pro-environmental behaviour is the outcome of their own pro-environmental attitudes or the product of social influence within the family, that is, a reflection of the dominating values and norms in the family group as manifested most clearly in their parents’ attitudes and behaviour. In addition, we examine the moderating effects of two family characteristics, parenting style and the “generation gap” (parent–child age difference), on the relative weight of adolescents’ personal attitudes vs. social influences within the family as predictors of adolescents’ pro-environmental behaviour. Results show that the adolescents’ pro-environmental behaviour is heavily influenced by the dominating norms within the family and in particular by how strongly they are manifested in their parents’ behaviour.

► Adolescents’ pro-environmental behaviour is studied in a survey of 601 families.
► The aim is to determine the effect of parental norms on pro-environmental behaviour.
► Adolescents’ behaviour is partly determined by their own attitudes towards the behaviour.
► Parental norms are as predictive of adolescents’ behaviour as adolescents’ attitudes.
