Over the last eight weeks, 30,033 (and counting) Green Challenge participants have pledged to shed 58,678,436 pounds of carbon dioxide, the equivalent of taking 5,998 cars off the road for a year.

Did you really cut beef from your diet, inflate your car tires, turn down your thermostat, and take the train instead of flying? The Green Challenge wrap-up quiz asks you to revisit your pledges. Will we meet our goal of a 20 percent reduction in collective carbon emissions? Only you can help us find out!
