"Republicans in Congress are introducing legislation to curtail the role of the U.S. Environmental Protection Agency in regulating greenhouse gases under the Clean Air Act and to prevent and roll back regulations intended to reduce air pollution such as mercury emissions from cement plants.
These efforts amount to attacks on the nation's health, the advocacy coalition Health Care Without Harm said [Tuesday].
On January 7, Congresswoman Marcia Blackburn, a Tennessee Republican, introduced H.R. 97, a bill that would amend the Clean Air Act to declare that greenhouse gases are not subject to the law. The co-sponsors - 46 Republicans and one Democrat - state that EPA greenhouse gas regulations are "job-killing" and are not authorized by Congress.
But members of Congress who support EPA regulation of greenhouse gases state that the Clean Air Act was passed by Congress with the intention of having the EPA regulate all air pollutants, including greenhouse gases, which were ruled to be air pollutants by the U.S. Supreme Court in 2007. "
