Research suggests adolescence is a critical period in terms of value formations and that there is a need for empirical studies examining values of youth in diverse educational settings as well as changes across one school year (Bogt, et al. 2001; Hofmann-Towfigh, 2007; Krishnan, 2008). Furthermore, environmental education research concludes on the lack of insights on students´ ideas of public and governmental environmental actions, compared to actions taken in the private sphere (Chawla and Cushing, 2007; Lundholm and Plummer, 2010; Levy and Zint, 2013;). This study explored changes of Swedish students’ values and beliefs in the efficacy of public and private actions, to solve climate change, over a year in business and economics education. Data comprises survey evidence of change of secondary students’ altruistic, biospheric and egoistic value positions (de Groot and Steg, 2007; 2008) and beliefs in climate change solutions. A survey was administered twice; first to 212 students aged 16/17 and then, a year later, to students in the final year of school (aged 17/18). Students followed courses in business economics and international economics in line with the national curriculum and additionally courses in civics, science and geography. 142 students participated both times and data were analysed to identify changes and relations between environmental values and beliefs. Results show a statistically significant increase in the importance of all three values. Exploring changes in relations between values and solutions show two significant findings at first measurement; both altruistic and biospheric values correlate to policy and pricing components. In the second measurement, biospheric and egoistic values related to new solutions; governmental along with private initiatives and transport policy. Finally, the study shows that after one year of education there are significant relationships between biospheric respectively egoistic value orientations and different solutions, and an increase in variation of belief-specifics.
