The Défi sans auto solo is a friendly competition between Quebec companies and institutions that is intended as a way to educate employees, students and citizens across Quebec on the use of sustainable transportation. To stand out, the participating organizations are encouraging their staff and student community to reduce their solo car trips. Whether through active transportation, public transit or even teleworking, the Challenge is an opportunity for participants to discover sustainable mobility or to become ambassadors of their sustainable mode of transportation to their colleagues.
