I am in need of case study information of business that have gone green and have shown an increase in revenues and savings. Preferably information in the education, hotel, medical and food sectors. I am leading the intitiative at my school to become certified green. My bosses want bottom-line figures. They want to know how can we profit by becoming certified? Can you please send me or direct me to any pertinent information I can present? Including maybe some graphs and charts?
