NIEHS is funded through an annual appropriation by Congress. The NIEHS budget supports extensive extramural research and a dynamic intramural research program, including clinical research, to advance critical understanding of how environmental factors can influence human biology and disease. In addition, NIEHS funds education and training opportunities to foster the development of the next generation of environmental health scientists.
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 NIEHS Superfund Research Program.
