The Colorado Environmental Film Festival (CEFF) is the premier environmental film festival between the two coasts, annually showcasing the world's best environmental films!

CEFF is a celebration of the power of film to inspire, educate, and motivate audiences to protect and preserve their environment. CEFF presents thought-provoking films and dialogue that raise awareness of a wide variety of interconnected ecological, social, and economic themes. Providing an experience for the audience that goes beyond simply viewing a film, CEFF inspires audiences to act!

*COVID-19 & 2023 FESTIVAL*

CEFF is more committed than ever to sharing powerful films that inspire, educate, and motivate people to protect and preserve the environment. We are in the early stages of planning our 2023 festival and hope to host both in-person events and online virtual screenings.. If circumstances prevent in-person screenings, we will pivot to an all-virtual festival. We will post potential pertinent updates regarding our festival both here and on our website ( as information becomes available and in the case of policy updates or changes. (Updated June 1, 2022)

Since 2006, the Colorado Environmental Film Festival (CEFF) has been a flourishing part of Colorado’s cultural landscape. Founded by a dedicated and passionate core group of environmentally-minded educators, filmmakers, and supporters, CEFF is Colorado’s first and only international film festival that is hyper-focused on environmental themes. Based in Golden since its inception, CEFF has entertained, enlightened, and educated thousands of festivalgoers over the years with hundreds of original and thought-provoking environmental films originating from around the globe. Each year CEFF carefully juries and presents a new catalog of films from around the world, encompassing a broad mosaic of topics that always reflect CEFF’s cornerstone mission to engage our participants to learn about ways to understand, preserve, and protect the environment.

If selected to screen at the annual festival your film will be considered for one of five unique festival awards available for the following categories:
o Best of Festival
o Best Short Film
o Best Feature Film
o Best Youth Film
o Spirit of Activism

  • The Colorado Environmental Film Festival did an incredible job of pivoting to a virtual festival due to a Covid surge. The festival was a terrific opportunity to watch other environmental films. I truly met my fellow filmmakers during the virtual Q&A's. Thank you, Colorado Environmental Film Festival for bringing audiences to screen "WILD in the Garden State."
