Overview

Randomized trial shows elevated emissions in redlined areas, suggesting ongoing racialized impacts on urban infrastructure.

Key Points

  • The study aims to investigate how historical redlining affects contemporary transportation emissions in US cities.
  • Combined data from Home Owners’ Loan Corporation grades with on-road carbon dioxide measurements.
  • Estimated multilevel models for 9661 census tracts across 194 US cities for the years 2010 and 2015.
  • Analyzed the relationship between affluence, whiteness, and emissions in different urban areas.
  • Redlined areas exhibit higher on-road CO2 emissions independent of current neighborhood characteristics.
  • Affluence and whiteness correlate strongly with emissions in greenlined areas, but not in redlined areas.
  • Public-transit commuting shares have minimal impact on emissions across different grades.
