These findings can help to mitigate pollution and assist with developing strategies to reduce the impacts of poor air quality on health.

Environmental Justice and Transportation — Pollution from the transportation sector has been a long-standing obstacle to advancing environmental justice, as many communities of color and low-income families live near areas where pollution from vehicles and engines is abundant, and therefore experience disproportionate exposures to this pollution. Through regulations, interagency partnerships, federal funding, and other actions, EPA seeks to address these inequities as it works to reduce pollution from the transportation sector.
