Cars and trucks are the number one hazardous air polluter, according to the EPA. Cancer-causing and asthma-inducing pollutants include Volatile Organic Compounds, Nitrogen Oxides and Particulates, and CO2, the major greenhouse gas. Air pollution rains out as water pollution. Increasing VMT increases pollution. Calculations are based on: 0.053 lb VOC /gallon, 0.13 lb NOx/gal, 28 lb CO2/gal and 0.012 lb PM10/mile (primarily reentrained road dust).
