The four-times Olympic gold medallist is again fronting a campaign for Recycle Now, to support the Woodland Trusts Christmas Card Recycling Scheme.
In September, he launched the Recycle Now campaign that uses national and local advertising to encourage people to recycle.
After retiring from the sport, Pinsent has already received a boatload of early Christmas cards wishing him well for the future.
He said: Its flattering to be sent so many cards, so I am glad Ill be able to recycle them all for this campaign.
Special collection bins will be placed in every branch of WHSmith and Tesco from January 5.
