We’re pleased to share the Health Effects Institute’s 2025 Annual Report: Expanding Our Vision for a Healthier Environment. This year’s report highlights the many initiatives, research, and programs that helped make 2025 such a successful year. This success comes in part from our many sponsors, board and committee members, researchers, partners, collaborators, staff, and others who work to help provide impartial science to inform decisions that foster a healthier environment for all.
