Environmental Film Festival in the Nation’s Capital (DCEFF)

"Since 1993, DCEFF has been the premier showcase of environmental films. Each March, we bring the world’s largest green film festival to museums, embassies, universities, and other cultural institutions across Washington, DC. In addition to the many thousands of audience members we serve with our in-person programming, DCEFF offers year-round virtual screenings to passionate and environmentally-conscious viewers across the United States and the world." The 2026 event runs March 19-28, with the theme "Against the Current." Films in any genre can be submitted for consideration by Dec. 1. Cash prizes available.
