A recent conference at Wesleyan University, “Pricing Carbon,” gathered a group of distinguished scientists, politicians, and thinkers to consider the principles of effective carbon pricing. An excellent roster of speakers included James Hansen, Bill Mckibben, four members of Congress, Gary Yohe, Dan Lashof, Peter Barnes, Charles Komanoff, Brent Blackwelder, and numerous others.
The highly recommended presentations from the conference are available here.
