Lindsey Baxter Griffith believes in turning bold clean energy ideas into real change by bringing people and leaders together. A lifelong climate policy strategist, she has spent her career finding smart, scalable ways to accelerate the energy transition. Before founding Clean Tomorrow, Lindsey served as Executive Director at Clean Air Task Force (CATF) Action and built deep federal experience in the U.S. Senate as climate policy advisor to Senator Markey (D-MA), where she authored and negotiated the Green New Deal. She later served as Chief of Staff for Energy Policy at the U.S. Department of Energy.
Lindsey knows how to get things done and brings curiosity, determination, and accountability to every challenge. Lindsey is currently a fellow at Georgetown’s Institute for the Study of Diplomacy and previously worked on the Millennium Challenge Corporation’s Climate Change Corporate Initiative—because she knows the value of building trust partnerships and turning ambitious goals into real-world impact. She also serves as a director on the board of Andrus-on-Hudson, a nonprofit skilled nursing facility supporting more than 200 post-hospital and long-term care patients.
Lindsey holds a Master of Science in Foreign Service from Georgetown University. She lives in Washington, D.C. with her husband and two children.
