Biography

Dr. Sonia Yeh is a research scientist at the Institute of Transportation Studies, University of California, Davis. She is a faculty member of the Graduate Group in Transportation Technology and Policy (TTP) and an adjunct professor at the Department of Engineering and Public Policy, Carnegie Mellon University. Her primary research interest is to advance the understanding of future energy systems and their environmental and social impacts, and to seek solutions that improve the societal process of making decisions toward a low-carbon energy system. Her expertise is in energy market economics and modeling, lifecycle analysis of greenhouse gas emissions, alternative transportation energy use and modeling, sustainability standards for biofuels, and technological change induced by government policy. She co-leads the UC research teams with UC Davis and UC Berkeley in supporting the implementation of California's Low Carbon Fuel Standard since 2007 and is the co-director of the National Low Carbon Fuel Standard Project. She serves on many governmental advisory panels and chaired expert workgroups for governments and NGOs.

Gasoline and diesel fuel extracted and refined from Canadian oil sands will release about 20 percent more carbon into the atmosphere over the oil's lifetime than fuel from conventional crude sources in the Unied States, according to a study by the U.S. Department of Energy’s Argonne National Laboratory; the University of California, Davis; and Stanford University. “The level of detail provided in this study is unprecedented,” said co-author Sonia Yeh, a research scientist at the Institute of Transportation Studies at UC Davis, who helped lead research on emissions related to land disturbance.

Oregon Democrats have placed a controversial and newly amended low-carbon fuel standard bill early on the 2015 legislative schedule despite Republican threats to block other important bills down the line if it passes. Researchers from the University of California-Davis told lawmakers the impact was around a third of a cent per gallon in 2014. “The exact purpose of (the) policy is to move away from the status quo and reduce emissions through more use of low-carbon fuels via market competition and technology innovation,” said Sonia Yeh, a senior researcher with the UC-Davis Institute of Transportation Studies who was involved in implementing the California program.

ITS-Davis researchers Sahoko Yui and Sonia Yeh warn that "if policies are not strictly enforced there is the potential to hugely increase greenhouse gas emissions from palm production," in their study of Brazil's deforestation policy for palm oil production.

Sonia Yeh, from the UC Davis Institute of Transportation Studies, explains that "expanding millions of hectares of Brazilian land to produce palm oil for food or for renewable, clean-burning biodiesel could result in extremely high emissions of carbon dioxide unless strict controls are put in place."
