  • HEI achieves its mission by:
  • Funding and supporting policy-relevant scientific research
  • Convening independent experts to select, oversee, and review scientific research
  • Bringing together government, industry, nongovernmental organizations, academia, and communities to help to guide research priorities
  • Synthesizing, interpreting, and communicating scientific evidence to audiences in the United States and around the world
  • Engaging with HEI audiences to facilitate use of its science in decision-making
  • The Health Effects Institute is a nonprofit corporation chartered in 1980 to provide high-quality, impartial, and relevant science on the health effects of air pollution. HEI receives balanced funding from government and industry. Other public and private organizations periodically support special projects or certain research programs.

    HEI has funded more than 380 research projects in North America, Europe, Asia, and Latin America, the results of which have informed decisions regarding carbon monoxide, air toxics, nitrogen oxides, diesel exhaust, ozone, particulate matter, and other pollutants. These results have appeared in more than 260 comprehensive reports published by HEI, as well as in more than 2,500 articles in peer-reviewed literature.

    HEI is governed by a Board of Directors and works with expert Research and Review Committees who, independent of sponsors and each other, evaluate research projects. Occasionally, HEI conducts its own research, but generally studies are conducted by investigators at academic and other research institutes around the world.
