Daniel S. Greenbaum
Dan Greenbaum joined HEI as its President and Chief Executive Officer in 1994. In that role, Greenbaum leads HEI’s efforts to provide public and private decision makers — in the U.S., Asia, Europe, and Latin America — with high quality, impartial, relevant, and credible science about the health effects of air pollution in order to inform air quality decisions in the developed and developing world.
Greenbaum has been a member of the U.S. National Research Council (NRC) Board of Environmental Studies and Toxicology and Vice Chair of its Committee for Air Quality Management in the United States. He recently served on the NRC’s Committee on The Hidden Costs of Energy and on their Committee on Science for EPA’s Future. Greenbaum also chaired the EPA Blue Ribbon Panel on Oxygenates in Gasoline and EPA’s Clean Diesel Independent Review Panel, which reviewed technology progress in implementing the 2007 Highway Diesel Rule. Greenbaum serves as the Chair of the Board of the International Council on Clean Transportation (ICCT), a non-profit organization providing technical analysis and support to the agencies involved in seeking clean vehicles worldwide. In May 2010, Greenbaum received the Thomas W. Zosel Outstanding Individual Achievement Award from the U.S. EPA for his contributions to advancing clean air.
Greenbaum has over three decades of governmental and non-governmental experience in environmental health. Just before coming to HEI, he served as Commissioner of the Massachusetts Department of Environmental Protection from 1988 to 1994, where he was responsible for the Commonwealth’s response to the Clean Air Act, as well as its award-winning efforts on pollution prevention, water pollution, and solid and hazardous waste. Greenbaum holds Bachelor's and Master's degrees in City Planning from the Massachusetts Institute of Technology.
