County Summary

The map below shows relative emission density (tons per square mile) by dividing counties into three groups, with the darker-shaded counties having higher relative emission density. This is not an indicator of air quality. To compare counties with respect to air quality and health-related information, visit the AirCompare Web site. To view county emission summaries, select a county from the drop-down menu or from the map. Results will appear beside the map.

*Counties on the map that show up white have no Nitrogen Oxides reported.
