Some 2,000 copies of the mailer are being distributed to delegates at the conference.

It has been designed by Creative Sweatshop and contains information about the benefits of using FSC-certified papers and images of a paper cut-out tree.

The hand-crafted paper tree growing out from a sheet of paper has been created using stocks from the Curios Collection, Keaykolor and Rives ranges.

The campaign also aims to show businesses that taking small steps, such as switching to FSC-certified paper, can make a big difference to the environment.

Gilles Pelissier, marketing director at Arjowiggins Creative Papers, said: "We are committed to changing attitudes and behaviour among end users, designers and printers when it comes to paper usage. This is why we have developed this innovative creative paper campaign."

Arjowiggins Creative Papers, in collaboration with international conservation charity the World Land Trust, has also committed to protecting one hectare of the Brazilian rainforest for each of the state leaders attending the summit, meaning that 65 hectares will be protected.

The Climate Change Conference began on 7 December and concludes on 18 December.
