Over the next 12 months, 20,000 agencies, designers, retailers and politicians will receive direct mail items that include a pack of six post cards, printed and distributed by Lateral Group.

A series of online and print advertisements, along with a competition to visit European forests, are also included in the initiative.

Two Sides was launched last year by the National Association of Paper Merchants (NAPM) in a bid to dispel the environmental misconceptions that surround the medium.

It claims that more trees are planted every year than harvested and that forests have grown more than 30% since 1950. It also said that producing a traditional newspaper can consume 20% less energy than reading news online for more than 30 minutes.

Martyn Eustace, who heads up the campaign, said: "This awareness campaign will target the end users and we hope that we will get them to choose paper as part of their marketing campaign."

So far, the campaign has largely been supported by suppliers and clients of the industry and in January, Two Sides said it would bolster its efforts to get printers on board (PrintWeek, 2 January 2009).

Eustace added that he hopes the campaign will have a knock on effect and encourage more printers to sign up.

Printers can join the campaign for £25 per million of UK turnover, although there is a minimum of £150.
