Environmental Justice: Who Bears the Burdens?

Environmental justice (EJ) is the principle that all communities deserve equal protection from environmental hazards and equal access to environmental benefits, regardless of race, income, or geography. The EJ movement emerged in the United States in the 1980s when civil rights activists documented that hazardous waste facilities, industrial polluters, and toxic sites were systematically sited in or near communities of color and low-income communities — not as a matter of coincidence, but as a predictable outcome of political and economic processes.

The evidence base is extensive. A landmark 1987 study by the United Church of Christ found that race was the strongest predictor of proximity to hazardous waste facilities in the United States — stronger than income, property values, or land costs. This finding has been replicated and extended by hundreds of subsequent studies. Communities of color breathe disproportionately higher levels of particulate pollution, live closer to highways and industrial facilities, have higher rates of childhood asthma and lead exposure, and face greater flood risk from inadequately maintained stormwater infrastructure.

The mechanisms are multiple and interact: lower property values in communities that already host industrial facilities attract additional facilities due to lower land costs; political underrepresentation reduces communities' ability to resist new facilities; lower household wealth reduces capacity to move away from hazardous areas; historical redlining and exclusionary zoning concentrated lower-income households of color in areas with poorer environmental conditions; and cumulative siting decisions by industries individually defensible can collectively create unacceptable cumulative burden on specific communities. Understanding these mechanisms is essential for designing EJ-informed policy that addresses root causes rather than only symptoms.
