Certified wood from sustainably managed forests

Stora Enso's UKP is made of traceable pine and spruce from sustainably managed Nordic forests. It is available with FSC® and PEFC certification upon request. These certifications provide third-party verification of responsible forest management and traceability throughout the supply chain.

Sustainable forest management helps secure the long-term availability of wood, our renewable raw material. The forests we harvest wood from are regenerated after harvest. We maintain traceability systems to track the origin of the wood used in our pulp production.
