Clean Air Federalism: Do States Race to the Bottom?

Proponents of federal environmental standards argue that competition for industrial development creates a “race to the bottom” in which states relax their own environmental standards to avoid losing businesses to states with more “business‐friendly” regulations. This article presents results from a unique survey of state clean air programs that show—contrary to the race to the bottom—a substantial number of states exceed federal EPA standards in a broad variety of clean air programs. Multivariate analyses of these state policies indicate that states strengthen their environmental programs in response to citizen demands rather than weaken their programs in deference to economic pressures.
