"After Federal Court Ruling, What's Next for States' Rights to Control Vehicle Emissions?"

In this article published on, Associates Patricia Boye-Williams and Allison Sapsford discuss the implications of the recently decided case, Green Mountain Chrysler-Plymouth-Dodge-Jeep v. Crombie.  In Green Mountain Chrysler, the U.S. District Court for Vermont held that, pending EPA approval, Vermont was authorized to regulate greenhouse gas emissions from automobiles and that Vermont's actions were not pre-empted by the EPCA or by national foreign policy considerations.  Among other things, the article provides a background on the role of automobile emissions regulations in national clean air policy, and describes several potential effects that the holding in Green Mountain Chrysler and other pending decisions may have on automakers and related industry groups.
