It’s Green Week here at NBCUniversal and we’re inviting our fans to take the pledge to use a reusable mug all week. Our message this year is “You don’t have to do a lot, to do a lot.” Which is true. Collectively, if we make one small change, like using a reusable mug all year, we could save 9 million trees.

We’ve got lots of rewards and incentives, which you can find out more about on the Mugs Save Trees page of our site, but we wanted to share this amazing illustration about the life-cycle of a paper cup. It seems that it takes a bunch of energy and natural resources to create a paper cup that we don’t often consider when we toss it after a single use. Check it out. Hopefully it inspires you to incorporate this small change into your lifestyle and to take the pledge now!
