Make It Easy and Fun: Some coworkers may balk at the idea of such changes, thinking it will create more work for them. Strive to make greening the office as user-friendly as possible; for example, set the office printer to default print double-sided. Put up funny, cheerful reminders to recycle or turn off the lights. Create an office-wide challenge to see which department can recycle the most paper in pounds in a month – winners get a pizza party!
