Yes, I'll take a little bit of a different tack. I think there are many things we know we can do right now, and some of them are beneficial. They're net negative cost. We do need some detailed analysis because we need to write a business plan on how we're going to get there. We need to count things: power plants, pipelines, whatever. We need to remove barriers to getting there. We need to bring that to the public so they know what's going on. It's that type of detailed analysis, and a little bit is being done now.
I think I'm very much of the opinion that if we put a reasonable price on carbon and do good analysis, we're going to find out we have a tremendous number of things we can do that are really quite manageable. These numbers that Stern is talking about will probably pop out of that type of analysis. It needs to be done; it needs to be transparent so that the public understands; it needs to be independent so that we know it's in our interests as a nation to do them; and then it's going to take a fair bit of courage to get on with it because there will be big opposition.
I believe it's totally doable. I believe the analysis will show it and that there are a tremendous number of cost-effective things when one imputes an environmental price on some of the pollutants we're dealing with. It's all sitting there; the technologies are out there, and others will come if we start down that path.
