Tomorrow evening, the 23rd annual Environmental Media Awards (EMAs), which recognize the best television episodes or films with an environmental message, will be presented at Warner Bros. Studios in Burbank, Calif.

The EMAs are given by the Environmental Media Association, a non-profit organization that was founded in 1989. The association mobilizes the entertainment industry in a global effort to educate people about environmental issues and inspire them into action.

Matt Damon and Hayden Panettiere are among some of the actors who will be honored tomorrow night. HBO’s Gasland Part II and VICE, as well as TNT’s Dallas, are nominated.

The awards ceremony kicks off at 6:30 p.m. (PT)/9:30 p.m. (ET) on October 19, and will be streamed live on the Environmental Media Association's Facebook page.
