BYOC (Bring Your Own Cup) BYOC. That's Bring Your Own Cup, and it's a great idea for a number of reasons, starting with the amount of paper you'll save over the course of a year: 23 pounds, give or take a latte, according to the eco-experts at Ideal Bite, an online source of tips for green living. If you extrapolate that out to even just the people in your office or all those who frequent your local coffee shop, a lot of waste could be eliminated and trees saved. On top of the earth-friendly benefits, opting for your own mug will earn you a discount at most coffee shops, and you can have fun searching for a container that matches your personality, like Decor Craft Inc.'s clever I Am Not a Paper Cup ceramic number, shown here ($20).
