In this edition of Wilson Center NOW, we are joined by Sharon Burke, Global Fellow with the Environmental Change and Security Program and Founder and President of Ecospherics.  Also joining us is Claire Doyle, Program Assistant for the Environmental Change and Security Program.  They discuss ECSP’s new policy brief, U.S. Governance on Critical Minerals, which “offers an overview of key policy considerations in securing a reliable, sustainable, and affordable supply of some of the most important commodities of the 21st century: critical minerals.”
