But Graham told reporters Thursday that they are still grappling with how to tackle greenhouse gas emissions from the transportation sector.

“The transportation sector is a problem. We are just dealing with that. I’m being honest with you – it’s a problem,” he said.

Graham confirmed that the trio have moved away from planning a so-called linked fee to address emissions from motor fuels.

Earlier discussions had involved a fee paid by petroleum companies – one “linked” to the price of carbon permits under the greenhouse gas limits applied to electric power plants.

“The linked fee proposal had its day and it’s not selling,” Graham said. “There are other ways to do this on the transportation sector and we are looking at those ways.”
