Combining climate, economic, and social policy builds public support for climate action in the US

Despite the gravity of the climate threat, governments around the world have struggled to pass and implement climate policies. Today, politicians and advocates are championing a new idea: linking climate policy to other economic and social reforms. Will this approach generate greater public support for climate action? Here, we test this coalition-building strategy. Using two conjoint experiments on a representative sample of 2,476 Americans, we evaluate the marginal impact of 40 different climate, social, and economic policies on support for climate reforms. Overall, we find climate policy bundles that include social and economic reforms such as affordable housing, a $15 minimum wage, or a job guarantee increase US public support for climate mitigation. Clean energy standards, regardless of which technologies are included, also make climate policy more popular. Linking climate policy to economic and social issues is particularly effective at expanding climate policy support among people of color.
