Hermione Norris, who recently appeared in the BBC’s Spooks series, is heading a campaign with the Woodland Trust to recycle this year’s 100 million Christmas cards.
All cards collected from the shops during January will be taken to paper mills to be recycled, with the money raised helping the Woodland Trust to plant new trees around the UK.
Norris said: “I want to challenge you to make it your mission to collect as many Christmas cards as possible! Sending cards is a lovely tradition, but instead of throwing them away after Twelfth Night, take your cards to a participating store, and pop them in the special bins provided.
“So do your bit this January and make it a green 2009!”
Woodland Trust chief executive Sue Holden added: “A world without trees would be a pretty desolate place. By recycling just one card each this year at participating WHSmith, Tesco, TK Maxx and Marks & Spencer stores throughout January, you can help us plant thousands of trees and move one step closer to achieving our vision of doubling native woodland in the UK.”
