JUDI GREENWALD is the vice president of technology and innovation at the Center for Climate and Energy Solutions. She oversees the analysis and promotion of innovation in the major sectors that contribute to climate change, including transportation, electric power, and buildings. Ms. Greenwald focuses on technology, business, state, regional, and federal innovation. She served on the Resource Panel for the northeast Greenhouse Gas Initiative and the California Market Advisory Committee, and as a policy advisor to the Western Climate Initiative and the Midwest Greenhouse Gas Accord Advisory Group. She previously served as the vice president for innovative solutions at the Pew Center on Global Climate Change, C2ES’s predecessor organization. Ms. Greenwald has nearly 30 years of experience working on energy and environmental policy. Prior to coming to the Pew Center, she worked as a consultant, focusing on innovative approaches to solving environmental problems, including climate change. She also served as a senior advisor on the White House Climate Change Task Force. As a member of the professional staff of the Energy and Commerce Committee of the U.S. House of Representatives, she worked on the 1990 Clean Air Act Amendments, the 1992 Energy Policy Act, and a number of other energy and environmental statutes. She was also a congressional fellow with then-Senate Majority Leader Robert C. Byrd, an environmental scientist with the U.S. Nuclear Regulatory Commission, and an environmental engineer and policy analyst at the EPA.

L. LOUIS HEGEDUS (NAE) is the retired senior vice president, R&D, of Arkema Inc., and a visiting distinguished fellow at RTI International. Research programs at Arkema supported market applications in the automotive, petroleum, energy conversion and storage, electronics, and construction industries. Dr. Hegedus was previously vice president, Corporate Technical Group, at W.R. Grace. Research programs included catalysts for petroleum refining, chemicals, emission control, and fuel cells; technical and electronic ceramics; electrochemical products including polymeric membranes for electric storage batteries of various types; and construction materials and products. Prior to joining W.R. Grace, Dr. Hegedus was affiliated with the General Motors Research Laboratories where he managed research on the development of the catalytic converter for automobile emission control. Before his graduate studies, he was an engineer with Daimler-Benz in Germany. He is a member of NAE, and he is a recipient of the R.H. Wilhelm, Professional Progress, Catalysis and Reaction Engineering Practice, and the Management Division awards of the American Institute of Chemical Engineers (AIChE) and the Leo Friend Award of the American Chemical Society (ACS)-Chemtech. At the occasion of their 100th anniversary, AIChE named Dr. Hegedus as one of “Hundred Chemical Engineers of the Modern Era.” He was a founding member of AIChE’s Commission on Energy Challenges and has served on several panels of the NRC’s Board on Chemical Sciences and Technology, including one on critical chemical technologies, one on the future of catalysis, and one charged with the international benchmarking of the U.S. chemical engineering competencies. Most recently, Dr. Hegedus served on panels of the National Science Foundation dealing with the manufacture of nanomaterials and with the development of rechargeable lithium battery technology. At RTI International, he co-edited and co-authored the book Viewing America’s Energy Future in Three Dimensions—Technology, Economics, Society. Dr. Hegedus obtained his Ph.D. in chemical engineering from the University of California, Berkeley, and his M.S. in chemical engineering from the Technical University of Budapest, from which he also received an honorary doctorate.

JOHN B. HEYWOOD (NAE) has been a faculty member at MIT since 1968, where he has been the Sun Jae Professor of Mechanical Engineering and director of the Sloan Automotive Laboratory. His interests are focused on internal combustion engines, their fuels, and broader studies of future
