Spare the Air in the San Francisco Bay Area

Spare the Air logo

There's a better way to work!  

Look for ways to share, shorten, or change your commute so you spend less time alone in your car and more time doing what you want to do. Be "in the know" by carpooling with coworkers. Take transit where you can finally finish that novel or clean out your inbox. Ride your bike to work and let your commute be your new gym. 

Find a better way to work and enjoy the many perks experienced by commuters who take transit, carpool, bike, or walk to work instead of driving alone.
