What I'm suggesting is first of all that the value of doing a tax, as opposed to let's say the cap and trade system or a regulation that says “You must reduce emissions by a certain amount”, is that it gives certainty to businesses about what the price is and allows them, if you've not put the price too high and it will still give them incentive, to look at new technologies that could be adopted to reduce carbon.
You then have the value of using the revenues—to the extent it raises revenue, which I'm suggesting, in terms of this restructuring of the federal fuel excise tax—in part to help fund tax credits for many businesses that are going to take on costly technologies in order to reduce carbon, of which carbon storage and capture is certainly going to be one.
