Kerry dismisses talk of ‘gas tax’ in climate bill

However, his comments also raised new questions about how the bill – which Kerry is crafting with Sens. Joe Lieberman (I-Conn.) and Lindsey GrahamLindsey Olin GrahamAlabama election has GOP racing against the clock Graham on Moore: 'We are about to give away a seat' key to Trump's agenda Tax plans show Congress putting donors over voters MORE (R-S.C.) – will address transportation sector carbon emissions.

The senators have reportedly been discussing a fee paid by petroleum companies – one “linked” to the price of carbon permits under the greenhouse gas limits applied to electric power plants. (Various iterations of the “linked fee” idea have been kicking around the climate debate for some time.)

But Kerry on Tuesday said “There is not even a linked fee, there is not a tax, there is nothing similar.”

Pressed for clarification about whether the “linked fee” idea has been jettisoned, he softened his comment slightly, stating, “Certainly not the way it was described previously, nothing like that.”

It has never been precisely clear how the fee would work or where in the petroleum supply chain it would be levied.

“The money we generate comes from the companies. It is an assessment on what they do in the carbon world. They are creating a carbon product, they are going to pay a fee,” Graham said of the fee on March 25. He also said that while some of it would be passed along to consumers at the pump, the bill would include a rebate mechanism of some sort to defray consumer costs.

Kerry, Graham and Lieberman plan to unveil their bill April 26.
