Accountability Studies on Air Pollution and Health: the HEI Experience
- 165 Downloads
Purpose of Review
Assessing health effects of air quality interventions is of ever-increasing interest. Given the prominent role Health Effects Institute (HEI) has played in accountability research, this review focuses on HEI’s recent experiences, the challenges it has encountered, and provides possible directions for future research.
Most accountability studies to date have focused on effects of relatively short-term, local-scale, and sometimes temporary interventions. Only a few recent accountability studies have sought to investigate large-scale, multiyear regulatory programs. Common challenges encountered include lack of statistical power, how to account appropriately for background trends in air quality and health, and difficulties in direct attribution of changes in air pollution and health to a single intervention among many regulatory actions. New methods have been developed for accountability research that has shown promise addressing some of those challenges, including use of causal inference methods.
These and other approaches that would enhance the attribution of changes in air quality and health directly to an intervention should continue to be further explored. In addition, integration of social and behavioral sciences in accountability research is warranted, and climate related co-benefits and dis-benefits may be considered.
