Thanks very much.
I left off on the question of border adjustments to carbon pricing. I was pleased that Mr. McCauley took it up. It's great to see some evidence of bipartisan interest in the idea. Mr. Burn offered some thoughts. I'm wondering if, given all this time to mull it over, other panellists had anything to offer on that front. If not, it would be entirely reasonable to come back with something in writing.
