UK Green Film Festival is the UK’s annual environmental film festival which returns to cinemas across the country from 20 June to 3 July 2026 with a powerful new programme of feature documentaries exploring the realities of a changing planet. From melting glaciers and rising seas to off-grid living and communities rebuilding after environmental disaster, this year’s films confront some of the most urgent environmental questions of our time with honesty, humanity and hope. Through intimate storytelling and striking cinematography, the festival invites audiences into worlds shaped by climate change, resilience and renewal - continuing its mission to spark conversation, deepen understanding, and inspire action through the power of film.
