The key point is that we, first of all, need to create incentives for technology to be adopted, and that's what a price on pollution across the economy is supposed to do, rather than carving out sector-by-sector emissions and then we don't have these various things. I think the committee is well placed to help the government design better programs to stress the scale of the investments that are needed. This is a problem we're facing across the economy and there are lots of people working on this issue and lots of federal funding starting to roll out.
It's hard to give a 10-second or 20-second answer on exactly what's needed.
