What is the Défi sans auto solo?

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.

The Défi sans auto solo team

Started in 2009 from an initiative of Roulons VERT, the Travel Demand Management Centre of Mauricie et du Centre-du-Québec, the Défi sans auto solo is now carried by the Association of Travel Demand Management Centers of Quebec (ACGDQ), which brings together eight Travel Demand Management (TDM) centers across the province.

Supported by the Ministère des Transports du Québec, these organizations are tasked with supporting employers, institutions and municipalities in the area of sustainable mobility. The TDMs offer transport consulting expertise and offer solutions to reduce the use of solo cars.
