This study investigates the association between historical redlining practices and the disproportionate siting of oil and gas wells in marginalized neighborhoods. Using data from 33 US cities, the researchers analyzed the relationship between Home Owners' Loan Corporation (HOLC) grades (reflecting historical redlining) and the density of oil and gas wells. They found that redlined neighborhoods (D-graded) had a significantly higher density of wells compared to higher-graded neighborhoods. Propensity score matching controlled for sociodemographic factors, strengthening the association between redlining and well density. The study concludes that historical racist policies contribute to environmental injustice by influencing the location of hazardous infrastructure.
