President Biden’s Leaders Summit on Climate has wrapped up. The event saw world leaders highlighting their countries’ respective climate commitments, calling for collective action, and attending breakout sessions designed to foster dialogue around climate finance and technological innovation, among other topics. After Vice President Harris and President Biden opened the summit, Secretary of State Antony Blinken offered further introductory remarks before the trio joined Climate Envoy John Kerry at a horseshoe-shaped table to watch speeches from the world leaders in attendance. Then fifteen additional cabinet heads, political appointees, and special advisors spoke or moderated sessions during over the next two days. These U.S. officials comprise the core leadership team tasked with implementing the administration’s “whole of government” climate strategy. Below, we introduce these key members in the order in which they first appeared during the Summit, and project the role each will play in the “whole of government” approach.
Antony Blinken, Secretary of State
After beginning his career in private law practice, Blinken embarked on a two-decade career in foreign policy service and leadership. He was a National Security Council staffer throughout President Clinton’s two terms then served for six years as Democratic Staff Director for the Senate Foreign Relations Committee. During the Obama presidency, Blinken was Deputy Assistant to the President and National Security Advisor to the Vice President, then Deputy National Security Advisor, and finally Deputy Secretary of State to John Kerry. Before returning to head the State Department in January, Blinken co-founded a political consulting firm and joined a small investment firm. As the United States’ chief diplomat, Blinken has a broad portfolio that goes far beyond climate change, but will remain deeply engaged on the topic due to the Biden-Harris administration’s perspective that climate is an essential aspect of foreign policy.
John Kerry, U.S. Special Presidential Envoy for Climate
Kerry is the head of the United States’ international-facing climate efforts, and appeared throughout the Summit in a sort of host’s or moderator’s role. Sworn in on the first day of the Biden-Harris administration, he serves as the first Special Presidential Envoy for Climate, and is the first-ever Principal entirely dedicated to climate change to sit on the National Security Council (NSC). Kerry comes to the position with substantial international credentials, having served as President Obama’s second Secretary of State, and negotiated the Paris Climate Agreement, which the United States officially rejoined in February.

Yellen spent her early career in academia as a faculty member of the economics departments of Harvard University and the University of California at Berkeley. In 1994, President Clinton appointed Yellen to the Federal Reserve Board of Governors, then named her Chair of the White House Council of Economic Advisers. In 2004, Yellen was chosen to serve as President and Chief Executive Officer of the Federal Reserve Bank of San Francisco, the first woman to hold the positions.

After leaving the Fed in 2018, Yellen was a fellow at the Brookings Institution and a founding member of the Climate Leadership Council. The first woman to lead the Treasury Department, Yellen will oversee the agency’s recently announced Coordinated Climate Policy Strategy and new Treasury Climate Hub to support and expand on its work connected to climate transition finance, climate-related economic and tax policy, and climate-related financial risks. In Yellen’s remarks during the Summit, she emphasized the need to “foster the growing market demand for climate-aligned investments.”
Brian Deese, Director of National Economic Council
Deese began his career in the think tank space, focusing on economic policy issues.

Over the past four years, Deese led BlackRock’s sustainable investing team before President Biden asked him to return to the NEC as its director. Deese and the NEC will focus on workforce disruption and shifts related to efforts to combat climate change. At the Summit, Deese did not moderate a panel or offer remarks, but sat to Secretary Yellen’s right during the climate investment session.

As head of DHS, Mayorkas oversees the Federal Emergency Management Agency (FEMA) and the federal response to severe climate events. Mayorkas used his remarks at the start of the adaptation and resilience breakout session to announce the creation of a DHS Climate Change Action Group, highlight FEMA’s just-issued request for information on how it can ensure that its programs advance equity and increase resilience, and discuss the ongoing electrification of DHS’s vehicle fleet.

The Pentagon has called climate change a national security issue and Austin will manage the climate footprint of the largest branch of the federal government. In his remarks at the Summit, Austin described the climate crisis as an “existential” threat and a “profoundly destabilizing force” for the world and offered examples of the financial and readiness cost of natural disasters on the U.S. military.
