If I can go to the Clean Fuel Standard Advocates witnesses, you talked about clean fuel standards quite a bit. I note there's also a commitment that 100% of new vehicles sold by 2035 will be zero-emission vehicles. On that, I was wondering if you had thoughts about the best structure for a cap.
Should we be going, as some people have suggested, with just increasing the price on carbon pollution, or would you suggest that a cap on carbon emissions would be better?
