Q: My coworker prints two copies of everything–”just in case.” How can I get her to be more eco-conscious?
A: Polite prodding is the right way to eco-educate your coworker–to a point. You could say, “Joyce, as you may know, the environment is one of my big causes. I hope you don’t mind my mentioning that printing duplicates uses up a lot of paper. What about saving a copy to your computer’s desktop instead of printing an extra?” After that, drop the topic; you don’t want to turn into the office eco-nag, and after all, her working style is her business.
