Have you ever seen a Fed Ex truck whizzing by with writing on the side touting its low emissions? Supermarket chains are getting in on greening their delivery fleets too. Major chains, Meijer and Winn-Dixie are purchasing efficient, low emissions diesel trucks which are expected to reduce CO2 and nitrogen oxides emissions from the air. Meijer itself projects a 47 percent reduction in particulate matter, a 55 percent reduction in nitrous oxide and a 3 percent reduction in carbon dioxide emissions – environmentalleader.com. Of course, this is a good marketing campaign but it is also a boon to their bottom line by reducing their fuel costs over time (they wouldn’t be doing it otherwise). Green can be profitable too!
