One of the most critical areas of the center’s work has focused on conducting research to affect environmental policy change. In the early years, the center conducted, documented and defended research that established the disproportionate impact of environmental insult against the African American and poor residents along the Mississippi River Chemical Corridor. The center also conducted substantive research in disparate health impacts for selected communities and communities of color in this region of the country, and successfully defended that research in judicial proceedings. In recent years, the center’s research has been directed at issues relative to the aftereffects of hurricanes Katrina and Rita and is aimed at affecting federal, state and city policy decisions.
