The Clean Air Campaign is challenging Georgia’s K-12 schools to raise awareness of clean commute options and to explore ways to reduce the number of idling cars in school zones. Clean Commute Week, which is March 3-7, is designed “to help Georgia schools educate their communities about the benefits of cleaner transportation methods like bus riding, biking, walking, carpooling and no idling— and to spark change on a group level,” said Gretchen Gigley, the organization’s director of education. Schools are encouraged to choose one or more green travel methods to promote throughout the week. Info: CleanAirCampaign.org/Schools.
