NIEHS is funded through an annual appropriation by Congress. The Office of Policy, Planning and Evaluation (OPPE) supports the NIEHS director and staff in defining and interpreting programs and research of the institute to Congress, as well as to the public, scientific, and public health communities. OPPE also serves as a liaison to help ensure NIEHS accessibility and responsiveness to Congress, various government, health, and science agencies and organizations, and the public.

Congressional Justifications and Statements

As part of the budget process, NIEHS annually submits a Congressional Justification to be included in the President's budget. Then Congressional subcommittees conduct hearings on the accomplishments and needs of NIEHS before approving its budget request. A separate Congressional Justification is submitted for the Superfund Research Program. The NIEHS budget supports extensive extramural research and a dynamic intramural research program including clinical research in the effects of the environment on disease. In addition, NIEHS funds education and training opportunities to foster the development of the next generation of environmental scientists.
