Thus, we expect the share of ZE trucks in operation to grow from less than 1 percent today to more than 75 percent in 2050 for all medium- and heavy-duty trucks. signs global commitment to 100 percent zero-emission trucks, buses at COP27,” Environmental Defense Fund, November 18, 2022. In November 2022, the United States committed that ZE truck sales nationwide would reach 100 percent in 2040. 4 The requirement to transition to ZE trucks may increase in importance if widespread adoption of commercialized autonomous technology furthers the cost-efficiency of autonomous vehicles (AVs), driving significant increases in the number of miles driven by AV trucks, leading to even higher emissions than currently projected. Unlike their ICE counterparts, zero-emission (ZE) trucks, such as battery electric vehicles (BEV) or fuel cell electric vehicles (FCEV) powered by hydrogen, do not produce direct tailpipe emissions. The United States faces a transition point where it must move toward renewable energy and zero-emission vehicles (ZEVs). 3 “Freight analysis framework,” United States Department of Transportation-Federal Highway Administration, February 1, 2023.

This legion of vehicles generates more than 25 percent of total greenhouse gas emissions (GHGs) from the transportation sector, including carbon dioxide and nitrogen oxides, pollutants that threaten the population’s respiratory and cardiovascular health. 1 IHS Automotive, AutoInsight, May 2022 EV-volumes, February 2022 McKinsey Center of Future Mobility Electrification Model, June 2022.

My work also appears in Population Studies, JAMA Network Open, Contraception, American Journal of Public Health, Perspectives on Sexual and Reproductive Health, American Journal of Obstetrics & Gynecology, and BMJ Sexual and Reproductive Health.
My sole-authored paper in Social Science & Medicine analyzes the narratives of 68 women living in two countries where abortion access was highly restricted (Ireland and Northern Ireland). These women either left the country to receive clinic-based care or obtained medications through informal channels to self-manage an abortion at home. In this work, I situate self-managed abortion within the continuum of (de)medicalization and reveal the ways medical technology and healthcare provision shape individual perceptions and beliefs about pain, the body, and the environment where care is received. My research interests include sexual and reproductive health, social demography, fertility, gender, and health policy. in Sociology at the University of Texas at Austin, where I was a fellow at the Population Research Center. Prior to joining UofSC, I completed my Ph.D. Hi there! I am an Assistant Professor of Sociology at the University of South Carolina.
