Abstract

In the United States, state governments have been the locus of action for addressing climate change. But the lack of a holistic measure of state climate policy has prevented a comprehensive assessment of their effectiveness. Here, we aggregate information from over 20 individual policies to develop a holistic index of state climate policies from 2000-2020. Our measure highlights variation between states which is unobservable in studies focused on single policies. Next, we examine the environmental and economic consequences of state climate policy. A standard-deviation increase in climate policy stringency is associated with a 4% reduction in electricity-sector CO2 emissions and a 2% reduction in economy-wide CO2 emissions. We do not find evidence that more stringent climate policy harms states' economies. Our results make clear the benefits of state climate policy, while showing that current state efforts are insufficient to meet the US goal under the Paris Climate Accord.
