The Trees4Trees Program is not a wood certification scheme. We go one better than that, we directly replant the trees that were harvested to make a product. The producer of the product that bears our logo has donated funds to Trees4Trees™ to plant the number of trees required to replace the wood they used in making the product. The WIN number and its link to a location on Google maps where the trees are planted are your proof that the manufacturer acted in a responsible way by replenishing the renewable resource that they used in your product.
