CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE DISTRICT OF COLUMBIA CIRCUIT
No. 05–1120. Argued November 29, 2006—Decided April 2, 2007
Based on respected scientific opinion that a well-documented rise inglobal temperatures and attendant climatological and environmental changes have resulted from a significant increase in the atmospheric concentration of “greenhouse gases,” a group of private organizations petitioned the Environmental Protection Agency (EPA) to begin regu-lating the emissions of four such gases, including carbon dioxide, un-der §202(a)(1) of the Clean Air Act, which requires that the EPA“shall by regulation prescribe . . . standards applicable to the emis-sion of any air pollutant from any class . . . of new motor vehicles . . . which in [the EPA Administrator’s] judgment cause[s], or contrib-ute[s] to, air pollution . . . reasonably . . . anticipated to endangerpublic health or welfare,” 42 U. S. C. §7521(a)(1). The Act defines “air pollutant” to include “any air pollution agent . . . , including any physical, chemical . . . substance . . . emitted into . . . the ambientair.” §7602(g). EPA ultimately denied the petition, reasoning that
(1) the Act does not authorize it to issue mandatory regulations toaddress global climate change, and (2) even if it had the authority toset greenhouse gas emission standards, it would have been unwise todo so at that time because a causal link between greenhouse gasesand the increase in global surface air temperatures was not un-equivocally established. The agency further characterized any EPAregulation of motor-vehicle emissions as a piecemeal approach to cli-mate change that would conflict with the President’s comprehensive approach involving additional support for technological innovation,the creation of nonregulatory programs to encourage voluntary pri-vate-sector reductions in greenhouse gas emissions, and further re-search on climate change, and might hamper the President’s ability to persuade key developing nations to reduce emissions...
