Want to improve air quality? Hop on a bus or train

I’m writing about the July 7 Sun-Times story, “Better breathing now, but more bad air days likely for Chicago due to climate change.”

Chicagoans need to know that one of the best ways to immediately and positively impact our air quality and reduce our greenhouse gas emissions is to choose public transportation. With more than one million trips per day, emissions from public transit vehicles make up less than 2% of the region’s transportation emissions. Passenger vehicles such as your car, truck or SUV account for 59%.
