You have replaced John Podesta as senior advisor to the president for international climate policy. In that role, you will lead the Biden administration$$s international climate policy agenda and will coordinate with other officials at the State Department. You have been charged with overseeing implementation of the energy and climate provisions of the Inflation Reduction Act $($IRA$).$ You have been asked by President Biden to look at the EV battery supply chain strategy to ensure that it complies with the following objectives of the IRA:

Provide economic opportunity and create new jobs;

Increase the resilience of the global supply chain by reshoring the supply chain;

Address human rights and environmental abuses associated with the supply chain; and

Require that an increased percentage of EV battery supply chain activities take place in North America to be eligible for certain tax credits.

You are scheduled for a briefing with the President and his staff to discuss the "biggest challenge" to accomplishing these goals set forth by the administration. The President would also like to know why you picked this specific obstacle and perhaps how it might be mitigated. You need to submit a brief, that is no more than one$-$page, in advance laying out your discussion.
