Nathaniel Keohane

Nathaniel Keohane is an environmental economist who served on the Council of Economic Advisers during the Obama administration, where he worked on climate and energy policy. He later served as vice president for climate at the Environmental Defense Fund and became president of the Center for Climate and Energy Solutions (C2ES). His research on carbon pricing design — cap-and-trade versus carbon taxes, border adjustments, and cost containment mechanisms — has been widely cited in policy design discussions. Keohane bridges economic theory and practical climate policy implementation. His work on the economics of clean energy deployment — examining how cost curves for renewable energy technologies have shifted over time and what policy instruments best support technology adoption — has informed debates about the optimal design of the Inflation Reduction Act's tax credit structure and how similar frameworks could be implemented in other jurisdictions seeking to decarbonize their electricity systems.
