Cap and Trade versus Carbon Tax - Kenneth Green of the American Enterprise Institute at the AIER Global Climate Change Conference (YouTube)

I’m pretty sure this is from the American Institute for Economic Research, not the AEI as stated in the headline.

The headline is correct that the speaker is Kenneth Green of the American Enterprise Institute. He was speaking at the AIER Global Climate Change Conference. I’ve added AIER to the headline.
