Transportation is the moving of people or things from place to place.
We all need to get to work, to school, and to shopping. Unfortunately, the type of transportation we choose may adversely impact the environment. While there have been many vehicle and fuel changes in the last 25 years which have greatly reduced air toxics emissions from highway vehicles, the number of vehicles on the road and the number of miles they travel is continuing to grow. Without additional controls, growth in vehicle travel will offset progress in reducing air toxics by early in this century. It is responsible for the choking, coughing, and stinging eyes associated with smog.
