Cumulative Impacts:?Office of Research and Development (ORD) Research and Next Steps
On this page:
In January 2021, President Biden signed Executive Orders (EO) 13985 and 14008 to advance racial equity
and support for underserved communities and to address the climate crisis. These EOs provide a
framework for stimulating action across the federal government to address health inequities in the
United States caused by disproportionate exposures to pollution and environmental degradation that is
exacerbated by racial, economic, and geographic factors and climate change. In support of these Orders,
EPA Administrator Regan issued an Agency-wide directive to take steps to better serve historically
marginalized communities using cumulative impact assessment (EPA, 2021a, 2021b). In response to this
directive, the Office of Research and Development (ORD) is resolved to strengthen the scientific
foundation for assessing cumulative impacts. This white paper provides definitions, research gaps and
barriers to implementing cumulative impact research at EPA, and recommendations for advancing
cumulative impact research going forward within ORD’s FY23-26 Strategic Research Action Plans.
