Why Is Everyone Wearing Green Ribbons at the Emmys?

At Sunday night's Emmys, one accessory got a ton of screen time: a green ribbon. Many of the cast and crew behind Transparent and Veep, alongside several other nominees and winners, sported the ribbon on their lapels. And at first, the reason why was a mystery on social media:

But if you zoom in enough (or get super close to your television), the answer was right on the ribbon: #DemandClimateAction. It's a campaign (opens in new tab) put forward by the National Resources Defense Council, which is circulating a petition (opens in new tab) online to get world leaders to do something about climate change. The petition will be delivered at a major summit in Paris this December. 

Green ribbons are also used (opens in new tab) to promote awareness of conditions such as cerebral palsy, kidney cancer, and mental illness, which are all worthy causes of a green ribbon. But for tonight, it's all about the environment—and that deserves support.
