Federalism and Climate Policy Innovation: A Critical Reassessment.

This article argues that the prospects for US state and Canadian provincial climate policy innovation and diffusion are limited in several respects. Subnational climate leaders tend already to be the cleanest states and provinces, and even they have been strategic in the sectors they regulate and the instruments they employ. In some cases, this selectivity appears to be motivated by opportunities to shift compliance costs to other states. Efforts to pool risks through state and provincial collaboration also are flagging in the wake of the Canadian and US federal governments' failure to adopt nation-wide policies to level the playing field.
