Stephen Fry, Bella Ramsey, and Ben Whishaw have signed a pledge to reduce the environmental impact of film and television production.

An eco-friendly clause can be added to contracts by the UK arts union Equity by means of a “Green Rider”.

Their rules include avoiding private jets and big trailers as well as bringing their own water bottles and coffee cups.

Strike actor Tom Burke also signed, saying he hoped it would “initiate a change in culture”.

According to him, things on set aren’t running as greenly as they should, and the whole industry needs to reevaluate what’s really important.

“Some of the things that are being discussed, like people wanting to travel on private jets, are status symbols, and it doesn’t just come from what we do as actors, it comes also from the media,” he said.

If we’re going to make a noise about caring, we need to unpick this and be a bit more mature about it.”

On Tuesday, Burke helped launch the scheme at the Edinburgh TV Festival. As far as I’m concerned, we can only keep our side of the street clean in life.One of the first films to use the scheme is Sir Mark Rylance’s short film Spirit of Place, which just finished filming.

Film production is notorious for its waste and un-ecological practices, according to him.

The statement added: “Just because we can’t do everything, doesn’t mean we can’t do anything. Let’s clean up our workplace.”

About 100 people have signed the plan, including Hayley Atwell, David Harewood, Bill Nighy, Paapa Essiedu, Nabhaan Rizwan, Juliet Stevenson, Dame Harriet Walter and Adrian Dunbar.

The Last of Us star Ramsey described it as “a practical way to improve sustainability in the film and television industry”.

An artist’s rider is a list of requests he or she makes at the venue or location where they are working. There is a list of things that an actor can agree to do when making a film or a show on this green rider.
