Instead of driving alone every day, encourage your employees to carpool with their colleagues, take transit, or bike to work. To help spread the message, posters from our current Spare the Air campaign are available to download using the links below. All posters are 11″ x 17″, but special sizes and formats are available upon request. For more information please email email@example.com. For tips and incentives on transportation alternatives, have employees visit STACommuteTips.org.
