Thanks very much, Mr. Chair.
Mr. Klein, thank you very much for being with us here today. I found this discussion very interesting.
One of the things you spoke about in your exchange with one of my colleagues early on in this hearing was the price on pollution. You have said multiple times today that you support that concept. I'm thinking, not just for the members in this room but also for my constituents and others who might be watching this at home, why is the price on pollution an important mechanism that works, in your view?
