A Question of Ethics—Clean Air Act. In the Clean Air Act, Congress allowed California, which has particular problems with clean air, to adopt its own standard for emissions from cars and trucks, subject to the approval of the Environmental Protection Agency (EPA) according to certain criteria.

Congress also allowed other states to adopt California’s standard after the EPA’s approval. In 2004, in an effort to address global warming, the California Air Resources Board amended the state’s standard to attain “the maximum feasible and costeffective reduction of GHG [greenhouse gas] emissions from motor vehicles.” The regulation, which applies to new passenger vehicles and light-duty trucks for 2009 and later, imposes decreasing limits on emissions of carbon dioxide through 2016. While EPA approval was pending, Vermont and other states adopted similar standards. Green Mountain Chrysler Plymouth Dodge Jeep and other auto dealers, automakers, and associations of automakers filed a suit in a federal district court against George Crombie (secretary of the Vermont Agency of Natural Resources) and others, seeking relief from the state regulations. [Green Mountain Chrysler Plymouth Dodge Jeep v. Crombie, 508 F.Supp.2d 295 (D.Vt.
2007)] (See pages 870–871.)
1. Under the Environmental Policy and Conservation Act (EPCA), the National Highway Traffic Safety Administration sets fuel economy standards for new cars. The plaintiffs argued, among other things, that the EPCA, which prohibits states from adopting fuel economy standards, preempts Vermont’s GHG regulation. Do the GHG rules equate to the fuel economy standards? Discuss.
2. Do Vermont’s rules tread on the efforts of the federal government to address global warming internationally? Who should regulate GHG emissions? The federal government?
The state governments? Both? Neither? Why?
3. The plaintiffs claimed that they would go bankrupt if they were forced to adhere to the state’s GHG standards. Should they be granted relief on this basis? Does history support their claim? Explain.
