PEFC is the world's largest organization for certification of sustainable forestry. Certification of forestry and eco-labeling of forest products is the forest industry's way of telling consumers that they produce products of forest raw material that come from responsibly used forests. The PEFC marking on a wood-based product shows that it is made from raw material that comes from forests that are used according to defined requirements for consideration of natural and cultural environments, social values and forest management. PEFC stands for "Program for the Endorsement of Forest Certification" and the organization has members all over the world.
