Climate change policy analysis has focused almost exclusively on national policy and even on harmonizing climate policies across countries, implicitly assuming that harmonization of climate policies at the subnational level would be mandated or guaranteed. We argue that the design and...

Economists have for decades recommended that carbon dioxide and other greenhouse gases be taxed--or otherwise priced--to provide incentives for their reduction. The United States does not have a federal carbon tax; however, many state and federal programs to reduce carbon emissions effectively...

Federal action addressing climate change is likely to emerge either through new legislation or via the U.S. EPA’s authority under the Clean Air Act. The prospect of federal action raises important questions regarding the interconnections between federal efforts and state-level climate policy...

Fourteen U.S. states recently pledged to adopt limits on automobile greenhouse gases (GHGs) per mile in an effort to reduce GHG emissions. We show that, because of interactions between this effort and the federal CAFE standard, 70-80 percent of the emissions reductions from new cars in adopting...

Fourteen U.S. states recently pledged to adopt limits on greenhouse gases (GHGs) per mile of light-duty automobiles. Previous analyses predicted this action would significantly reduce emissions from new cars in these states, but ignored possible offsetting emissions increases from policy-induced...
