Greenhouse Gas Regulation Under the Clean Air Act: Structure, Effects, and Implications of a Knowable Pathway
Absent legislative intervention, CAA regulation of GHGs is moving beyond mobile sources to the industrial and power facilities that emit significant U.S. GHG emissions. The authors analyze the mechanisms available to EPA for regulating such sources, and identify one, NSPS, as the most predictable, likely, and practical, i.e., knowable, pathway. Indeed, EPA announced in late 2010 that it intends to pursue this pathway.
