A new study published June 10 in Science Advances by University of Washington researchers provides a comprehensive analysis of air quality inequity in the United States. It examines how disparities in exposure to air pollution have changed by state and economic sector from 2002 to 2019.
Despite overall improvements in air quality, communities of color and low-income communities continue to face disproportionately higher pollution exposure.
Key Findings
- The study created the first map cataloging changes in air quality inequity across 11 economic sectors.
- Specific example: Disparities in construction-related emissions in Florida increased significantly during the study period.
Implications
The findings and database are intended to help policymakers prioritize environmental justice projects at the state level.
