Title: Gina McCarthy, former U.S. EPA Administrator, Director of C-CHANGE (Center for Climate, Health and the Global Environment) at the Harvard T.H. Chan School of Public Health Bio: Gina McCarthy is Professor of the Practice of Public Health in the Department of Environmental Health at Harvard T.H. Chan School of Public Health and the Director of the Center for Climate, Health and the Global Environment. In this capacity, she leads the development of the School’s strategy in climate science, health, and sustainability; strengthens the climate science and health curriculum; and liaises with climate science leaders across the University. McCarthy has been a leading advocate for common sense strategies to protect public health and the environment for more than 30 years. She served under President Barack Obama as the 13th Administrator of the EPA from 2013–2017. Her tenure as EPA Administrator heralded a paradigm shift in national environmental policy, expressly linking it with global public health. She led EPA initiatives that cut air pollution, protected water resources, reduced greenhouse gases, and strengthened chemical safety to better protect more Americans, especially the most vulnerable, from negative health impacts. McCarthy signed the Clean Power Plan, which set the first-ever national standards for reducing carbon emissions from existing power plants, underscoring the country’s commitment to domestic climate action and spurring international efforts that helped secure the Paris Climate Agreement. McCarthy also worked with the United Nations and the World Health Organization on a variety of efforts and represented the U.S. on global initiatives to reduce high-risk sources of pollution.
