A handheld fan may have been the most popular accessory for Emmy-goers battling the L.A. heat on Sunday night.

But it was a little green ribbon that was really capturing attention on the red carpet.

Stars like Outstanding Lead Actor in a Comedy Series winner Jeffrey Tambor, his Transparent co-star Gaby Hoffmann, Outstanding Lead Actress in a Comedy Series winner Julia Louis-Dreyfus, Louis C.K. and Don Cheadle all had the ribbons pinned to their Emmys finery – and Twitter wanted to know why. //

The campaign is backed by the National Resources Defense Council. They currently have a petition open online to encourage world leaders to take action against climate change, and will present the document to said leaders at a summit in Paris in December.

It’s been a night for activism – Allison Janney spoke out about addiction during her speech, and Tambor advocated for transgender rights in his.
