Dr. Yeh's research interest is to advance the understanding of future energy systems and their environmental and social impacts, and to seek policy solutions to improve the sustainability of future energy systems. More specifically, Dr. Yeh's research focuses on providing better understanding of how technologies, economic and social changes affect future energy demands and environmental outcomes such as greenhouse gas (GHG) emissions, air and water pollution, resource depletions, and land use change. Her work is used to develop government policies, especially incentive-based policies, to induce innovation and the penetration of low-carbon technologies.
Dr. Yeh applies her research to actual policy design and implementation, particularly climate policies in California, including the California Global Warming Solutions Act (AB32), the Low Carbon Fuel Standard (LCFS) and the Sustainability Plan for the Alternative and Renewable Fuel and Vehicle Technology Program (AB118). She has served on many governmental advisory panels and chaired expert workgroups for governments and NGOs. She serves on the Energy Committee of the Transportation Research Board of the National Academies.
