Welcome to the CLEAN AIR CLUB!

Cook-Illinois is working together with kids like YOU to keep our air clean!  Cook-Illinois buses run on biodiesel fuel made in part of soybean oil.  This is a HUGE step toward cleaner air for all of us.  You can make a difference too. See how on this website.

Cook-Illinois Corporation, the country's largest family owned and operated school bus company, is now using biodiesel in over 90% of its school buses.
