One of the biggest challenges countries face across the world is climate change. To address this global challenge, it is necessary to implement measures that reduce greenhouse gas emissions, which in democratic societies depends on public support. This thesis aims to investigate the role political trust has for Europeans in 21 countries in supporting different types of climate change policies and whether ideology influences this relationship. The research questions asked are “Does political trust increase the support for climate change policies?“ and “Does a right-leaning ideology increase the association between political trust and support for climate change policies?”. By using multivariate regression analysis on the eighth round of the European Social Survey (ESS), this thesis finds that political trust is positively associated with support for climate change policies. However, this study did not find support that a right-leaning ideology increases the impact political trust has on support for climate change policies. These findings enhance and extend the understanding of factors determining public attitudes toward climate change policies.
