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 developments. In the presence of federal policies, to what extent will state efforts be costeffective? How does the co-existence of state- and federal-level policies affect the ability of state efforts to achieve emissions reductions?

"Because a cap-and-trade system would reduce California's overall greenhouse gas emissions, it would also lower the state's emissions of the co-pollutants. Still, it's possible, though unlikely, that co-pollutant emissions would increase in a particular locality. But here it's crucial to recognize that existing air pollution laws address such pollutants, and so any greenhouse gas allowance trades that would violate local air pollution limits would be prohibited."
