Advisory Council Members

Advisory Council

Complementary to the T20’s Workstreams, the T20 U.S. Advisory Council will once again reflect on and feed carefully researched policy ideas into the G20 U.S. presidency priority themes across the Sherpa and Finance Tracks and beyond, and in light of rapid changes in global and regional multilateral governance. Each Advisory Council member will prepare a brief Policy Solutions paper over a short period in response to a G20 Member State’s or regional grouping’s request. They will also provide substantive feedback on Incubator Concepts, such as a new T20 Foresight Hub and revival of T20/G20 Implementation Roadmaps and Scorecards. The work of the Advisory Council is facilitated by monthly meetings of a technical Coordination Team, which includes diverse representation from active T20 network partner think tanks.
