Study finds modifying urban form may be a strategy to reduce air pollution

Green Car Congress

Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution. Their paper appears in the ACS journal Environmental Science & Technology.
