Understanding what types of climate policies people support is crucial for policymakers. A study in Sweden looked at how people's views on climate policies are influenced by factors like cooperation and fairness. They found that people are more likely to support policies when costs are shared fairly among everyone. Additionally, support for climate policies depends on whether other levels of government are also adopting similar policies. This means unpopular climate policies could become more popular if they are funded fairly and implemented by multiple levels of government.
