Young people are important to include in the efforts to combat climate change and other environmental problems since they are the future leaders of society, as well as being citizens of today. This group will be the ones handling the future negative consequences of different sustainability problems and they are potential important influencers regarding pro-environmental behavior in a family context. At the same time, children and adolescents are said to be particularly vulnerable to psychological stress associated with sustainability problems such as climate change. In this symposium, studies with adolescents from different parts of Europe on how they relate to climate change and other environmental problems are presented. In study 1, Associate professor Maria Ojala, Örebro University, focuses on relations between climate-change worry, climate-change efficacy and subjective well-being among Swedish early adolescents. In study 2, Professor Rita Žukauskienė and colleagues at Mykolas Romeris University, investigate the bidirectional influences of parents’ and adolescents’ information-induced pro-environmental intentions and behavior in Lithuania. In study 3, Professor Katariina Salmela-Aro and colleagues, Helsinki University, take a person-oriented approach to identify different climate change groups based on climate change related knowledge, stress, inadequacy and engagement among late adolescents in Finland. All three studies deal with important preconditions for promoting both subjective well-being and the inclusion of adolescents in societal deliberations around how to deal with climate change. The results are discussed in the context of developmental science and sustainable youth development by Professor Anne Petersen, University of Michigan.
