The FSC label guarantees that the materials for wood and paper products are sourced from responsibly managed forests. With this partnership, PostNL will actively strive to increase the proportion of FSC paper on the Dutch market. In negotiations with print and paper suppliers PostNL demands that these suppliers have an FSC-certificate. Packaging material for clients is where possible partially or fully FSC-certified. Through the post offices and shops, we annually sell many millions of euros of cardboard products that are for 80% FSC-certified; for example greeting cards, envelopes and packaging material.
