Reduce Southeast Michigan’s carbon footprint by choosing eco-friendly commuting during the Detroit Commuter Challenge. Through the entire month of May, instead of driving alone to work, consider taking an alternative form of transportation (carpooling, bus, vanpooling, biking, walking, telecommuting). Sharing the ride reduces traffic congestion and carbon emissions, and promotes better health and thriving communities. Start logging your commutes toward our carbon reduction goal and you might pick up one of our great prizes along the way. Your miles make the difference!
