Supreme Court Takes Up Challenge To Sweeping EPA Carbon Rules

The appeal was supported by the U.S. Chamber, the Competitive Enterprise Institute and the Southeastern Legal Foundation as well as companies like coal producer Peabody Energy BTU -0.95%.

EPA, it will have to consider the true sweep of the Clean Air Act, which critics say was intended to combat local pollution like Los Angeles smog, and not international problems like global warming.
