Four Decades of Trusted Science
HEI was founded in 1980 on the heels of a tumultuous period, with great upheaval in the way Americans viewed science and the environment. In 2020, the country found itself in another time of uncertainty. While much has changed since HEI’s launch 40 years ago, the need for impartial, trusted science — the need for a common ground on which to base decisions — endures.
In this year’s annual report, we look to HEI’s past, present, and future to examine how investing in rigorous science can shed light on decisions with lasting impacts for our health, economy, and the world.
