Have you ever wondered how much your car or other motor vehicle contributes to air pollution? We’ve designed this evaluation tool to let you find out just that! Just plug in the details of your current travel habits, and find out how much you contribute. Then, try out some different options of how you might generate less air pollution by changing your commute habits.

Notice in the output results how you can make a difference! We encourage you to do your best to try to integrate carpooling, public transit, bicycling, and/or other strategies into your commuting habits. You might find other added benefits to these, like decreasing your travel costs, exercise, time on transit to use for other things, and more!
