Increasingly, researchers are developing new metrics and interdisciplinary approaches for characterizing disparities in air pollution exposure and associated health risks across race, income, socioeconomic status, geography, and other factors. This new research provides new opportunities for communities, policymakers, and regulators to utilize equity information in decision-making. Many policymakers at state and federal levels are interested in incorporating such technical assessments into policy decisions around air pollution monitoring, environmental permitting and enforcement, and addressing environmental injustice. For example, in the US several policies have been proposed or enacted that seek to use such research to identify and address disproportionate burdens of air pollution exposure and health impacts. This session will explore innovative research for assessing (1) equity dimensions of air pollution and changes in air pollution, (2) cumulative impacts of environmental stressors, and (3) integration with policy decisions.
