The present study examines intergenerational transfers of pro-environmental behaviours between parents and children. In a survey study involving 600 Danish families, we examine whether children's pro-environmental behaviours can be determined by their parents' attitudes and behaviours with respect to three "green" consumption activities: buying organic/environmentally friendly products, handling waste responsibly, and energy saving activities. In addition, we examine the effect of parenting on adolescents' pro-environmental behaviours by including a particular aspect of parenting style: parental autonomy support. Results show that the adolescents are influenced by their parents' behaviour, and especially how they perceive parents' behaviour, which seems to depend on how visible these behaviours are to them. Furthermore, parenting style influences the adolescents' behaviour in various ways.
