This report presents a study led by Patrick L. Kinney at the Boston University School of Public Health. Kinney and colleagues evaluated major national regulatory policies that were implemented in China between 2008 and 2019 to reduce air emissions. This study represents an impressive example of a large-scale accountability study that shows the effectiveness of implementing a suite of air pollution regulations.

This report presents a study led by Lea Hildebrandt Ruiz at The University of Texas at Austin. Hildebrandt Ruiz and colleagues examined population exposures to air emissions and noise in a major US oil and gas region and developed a model for use in multiple regions to predict population exposures and assess the effectiveness of interventions intended to mitigate emissions to the air.
