EPA Releases Greenhouse Gas Document for Public Comment
"Today EPA released an Advance Notice of Proposed Rulemaking (ANPR) soliciting public input on the effects of climate change and the potential ramifications of the Clean Air Act in relation to greenhouse gas emissions.

"The ANPR reflects the complexity and the magnitude of the question of whether and how greenhouse gases could be effectively controlled under the Clean Air Act," said EPA Administrator Stephen L. Johnson.

Today's action is in response to the April 2, 2007 Supreme Court decision in Massachusetts v. EPA, which found that greenhouse gas emissions could be regulated if EPA determines they cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare. With the ANPR, EPA is evaluating the broader ramifications of the decision throughout the Clean Air Act, which covers air pollution from both stationary and mobile sources."
