The Princeton Environmental Film Festival is a signature event of Princeton Public Library held annually at the Sands Library Building, 65 Witherspoon St., Princeton. The festival also includes virtual screenings and special events scheduled periodically throughout the year.

Founded in 2006, the festival’s mission is to share exceptional documentary films and to engage the community in exploring environmental sustainability from a wide range of perspectives.

Screenings are free and are often accompanied by a Q&A with film directors and producers and talks by invited speakers. The festival also presents related events with community partners to provide opportunities to participate in sustainable actions and initiatives year-round.

As the festival evolves and its sustainability is considered, organizers are mindful of expanding its reach while maintaining its identity as a meaningful local event.
