Ali Zaidi serves as Assistant to the President and National Climate Advisor. In this role, he leads the White House Climate Policy Office, which coordinates policy development and President Biden’s all-of-government approach to tackle the climate crisis, create good-paying, union jobs, and advance environmental justice. Zaidi is a longtime advisor to President Biden, having provided counsel and leadership on climate policy development, legislation, and executive action from day one of the Administration and on the Biden presidential transition and campaign. Before his current role, he served as Deputy National Climate Advisor. During his time in the Biden-Harris Administration, Zaidi has led on efforts to re-establish U.S. climate leadership, set a national target to cut greenhouse gas emissions by 50-52 percent by 2030; deliver robust executive actions, including regulatory, investment, and procurement-based initiatives; and secure the largest legislative wins on climate in U.S. history, through the Bipartisan Infrastructure Law and Inflation Reduction Act. Together these efforts have advanced the largest annual deployment of solar, wind, and batteries; brought together the U.S. auto sector around an all-electric future; tackled super-pollutants like methane and HFCs; bolstered domestic adaptation and resilience; and centered U.S. climate action around workers and communities, prioritizing good-paying union jobs and the critical work of environmental justice.

Zaidi has advised non-profits, including as a Trustee of the Natural Resources Defense Council, and counseled the private sector, as an attorney who helped launch a sustainable investment practice. Zaidi immigrated from Pakistan and grew up outside Erie, Pennsylvania. He received an A.B. from Harvard University and J.D. from Georgetown University.
