County Emissions Map -
criteria air pollutants

Map shading patterns (colors) indicate each county's total annual emissions of the criteria air pollutant you select. The map legend gives the numeric range of pollutant emissions associated with each shading pattern, which correspond to national percentile ranges. Optionally, the map can display pollutant emissions density, amount per square mile of county land area.
