Automobile emissions pose a threat to human health as well as the environment.  The various pollutants, which include nitrogen oxides, carbon monoxide, carbon dioxide, hydrocarbons, ozone, and suspended particulate, are products of the burning of fossil fuels.  They are a primary source of air pollution, causing serious human health defects such as respiratory disorders (e.g. asthma and bronchitis). This air pollution also contributes to acid rain and smog, which have widespread effects on areas far beyond where the pollutants are emitted.

 Many proposals have been made in attempt to combat and reduce the presence of these pollutants by designing catalytic converters for vehicles and encouraging people to drive less, especially when air quality advisories are in effect.  However, this is not enough.  More action needs to be taken to educate people about the harmful effects of driving and the alternative options that exist.  As ERS 285 students, and actors in the WATgreen group, we have decided to make an attempt to encourage people to help the university achieve the goal of a walk-in campus.

 Previous studies that have been undertaken in this area of study include the following: Micro-commuting on Campus, University Transportation System: 1997 Project Study, University Transportation Commission, and Transportation To and From Campus, 1991 (
