In the United States, poor people and people of color experience higher cancer rates, asthma rates, mortality rates, and overall poorer health than their affluent and white counterparts. The Environmental Justice Movement (EJM) links these health disparities to higher concentrations of environmental pollution sources in these communities. This disproportionate exposure to environmental harms in low-income, minority communities is known as “environmental injustice.” Since the EJM’s inception in the 1960s, empirical evidence of environmental injustice along racial and socioeconomic lines has been produced time and again. Vulnerable populations, however, continue to bear a disproportionate burden of society’s environmental harms, as illustrated in the recent water crises in Flint, Michigan, and St. Joseph, Louisiana.
A commitment to eradicating environmental injustice requires a nuanced understanding of its causes. EJM activists often highlight corporations’ role in creating environmental injustices, arguing that firms actively discriminate against racial minorities when making decisions about where pollution sources will be placed. More recently, however, many in the movement have recognized the causal complexity of environmental injustice.
Disentangling the causes of environmental injustice presents an empirical problem common in social science: it can be nearly impossible to isolate causal variables when it comes to human phenomena. Attempting to address this problem, researchers have developed innovative methodologies to test various theories of causation for environmental injustices. While it is clear that discriminatory siting plays a role, other causes may help explain both the behavior of firms and the disparate environmental harms experienced by low-income populations and minorities: Regulators may enforce environmental laws and regulations unequally, affected communities may lack political power, and market dynamics may drive both businesses and residents to low-cost real estate. It is important to understand the contribution of each of these to environmental injustice because they may call for different policy responses.
This paper surveys the evidence for each of these possible causes of environmental injustice. I conclude that, because empirical research shows that discriminatory siting, unequal regulatory enforcement, and unequal political power are the major culprits for environmental injustice, policymakers should work to level the playing field and allow for meaningful stakeholder participation in siting decisions and increase enforcement efforts in minority and impoverished communities.
