Negative emissions technologies aim to combat rising atmospheric carbon emissions by capturing and removing carbon dioxide already present in the atmosphere and sequestering it safely underground or for reuse. Assessing the potential of these technologies requires insights from the social sciences—including economics, public policy, political science, sociology, and life cycle assessment, among others—on issues like how they might integrate with existing energy systems and how energy consumers and producers would respond to their deployment. Funds from this grant support the creation of a social science research fellowship program across multiple universities that will aim to foster research by young scholars interested in studying negative emissions technologies. Coordinated by Peter Schlosser at Arizona State University, a multidisciplinary committee will review and select four promising postdoctoral researchers for support and embed them for two years at one of a number of partner universities involved in negative emissions social science research.  In addition to salary support for each fellow, grant funds will support networking, learning, and professional development activities for the fellows, including opportunities for fellows to present their research to one another and to other scholars and practitioners in the energy community at large.
