The Hill 
April 2, 2013
The top Republican on the Senate’s Environment committee said that President Obama wants to impose a tax on carbon dioxide emissions, a proposal the White House has flatly ruled out offering.
“That is the ultimate goal of this president,” Sen. David Vitter (R-La.) said in an interview  with WND.com.
White House press secretary Jay Carney said in mid-November that “We would never propose a carbon tax, and have no intention of proposing one.”
Vitter and other conservative lawmakers and groups have stepped up their campaigns against the notion of imposing a tax on industrial carbon emissions, which would require legislation to achieve.
