Carbon Control News reports that,
The Obama EPA is explicitly saying for the first time that a pending greenhouse gas (GHG) vehicle emissions rule, when finalized, will define carbon dioxide (CO2) and other GHGs as regulated under the Clean Air Act and will therefore trigger mandates for new power plants and other stationary sources to limit their GHGs.
The purpose of this threat, of course, is to scare industries and Congress into a cap-and-trade bill this fall.
