A Greener Festival, the U.K. initiative set up to make live music festivals safer and cleaner, has launched a voluntary award scheme to highlight the most environmentally-friendly events.

According to organizers, the first festivals to sign up to the award scheme include some of the U.K.'s biggest: Glastonbury Festival, Carling Weekend - Leeds and Reading, Latitude Festival, and Download Festival.

Others, such as Hyde Park Calling, the O2 Wireless Festival, Bestival, and Truck have also pledged to do so.

To commit to the scheme, a festival's organizer must answer a checklist of sixty questions and commit to its "A-Z" of green priorities. Examples of the priorities range from "All car parking charged for as an additional cost" to "Aim for zero waste and leave no trace."

"We don't expect festivals to be able to meet every single point on our check list, but they must reach a minimum standard," said Ben Challis, co-founder of a Greener Festival and Glastonbury Festival's general counsel. "They need at the very least to have a coherent transport and travel policy promoting public transport; they must consider ways to reduce waste and pollution; they must have recycling on the site, and they must protect the environment and wildlife."

Organizers said they are also talking with festivals in Australia, the United States, Finland and Serbia "about improving their environmental efficiency and promoting green issues."
