"A well-designed carbon tax is probably the single best tool for fighting catastrophic climate change and safeguarding the earth for future generations. It can also be a key component of tax reform and deficit reduction, both of which would enhance the nation’s competitiveness. Much of the world is already heading for a carbon tax: the United States should get out in front and lead the way. "
Everyone wants a simpler tax code, this is not a partisan issue. There is no reason this couldn't be revenue neutral either, though it could also be used to reduce the deficit. There is also wide agreement that "pricing" carbon would discourage production of carbon.
