What is the Massachusetts Clean Air Challenge?

Every year, Massachusetts travelers strive to improve air-quality by choosing more sustainable transportation options during the Massachusetts Clean Air Challenge in September. This year, Massachusetts challenges you to explore your commuting options and Shift Your Mode from September 22nd-26th  Let's work together to show how much we can save in money and carbon emissions throughout the entire Commonwealth in one work week!


Get Involved!

Participating in the MA Clean Air Challenge is FREE and it's easy! #ShiftYourMode and try traveling by foot, bicycle, carpool, vanpool or transit as many days as you can from September 22nd-26th. Track your green trips in NuRide, where each trip you log will help you earn points toward discounts at great local businesses. In honor of the MA Clean Air Challenge, we will be giving away additional prizes all week to some lucky NuRide users and to our followers on social media who participate in our photo challenge!
