Societies of today are faced with climate change challenges and need to take measures to reduce emissions and gain support for such actions by their citizens as in the form of taxation, or other forms of government interventions. Several instruments have been developed to capture attitudes towards the roles of markets and governments in the economy. We report a study investigating undergraduate economics students’ knowledge and attitudes towards government interventions on markets addressing climate change. Results show that students change attitudes to policy and become more knowledgeable in economics after one semester, however, knowledgeable students do not have different attitudes toward environmental policy instruments in comparison to less knowledgeable. In order explain this attitudinal change, further research is needed.
