We need to achieve the polluter-pays principle. We need to have them paying for a good chunk of the cost they're incurring on the environment right now. Then we could use some of that revenue too. Of course, one option would be to incent additional emission reductions through some kind of technology fund. That is a possibility.
But at the very beginning, we need to internalize some of those environmental costs and get the price signals, the incentives, right.
