The Cannes Film Festival has always been about the celebration of cinema and glamour. However, in 2025, the organisers added another aspect of celebration to this prestigious annual event - sustainable fashion. Starting in 2025, the organisers of the Cannes Film Festival have also launched the Cannes Sustainable Fashion Week, a celebration of couture with environmental consciousness. The event runs concurrently with the Film Festival and aims to highlight sustainable fashion, featuring runway shows, talks, art installations, and showcasing sustainable materials.

The Cannes Film Festival organisers have also taken measures to make its proceedings sustainable. This includes a complete elimination of single-use plastic during the festival, as well as the use of electric cars and redesigning of the materials used for the red carpets at the event.
