The Forest Stewardship Council mission is to promote environmentally sound, socially beneficial and economically prosperous management of the world's forests. Over the past 20 years, FSC has earned a reputation as the most rigorous, credible forest certification system. Independent FSC-accredited Certification Bodies ("certifiers") verify that all FSC-certified forests conform to the requirements contained within an FSC forest management standard. The FSC system includes two different types of certificates: Forest Management and Chain of Custody. Chain-of-Custody certification applies to manufacturers, processors and traders of FSC-certified forest products. It ensures the validity of claims associated with all FSC-certified material and products throughout the production chain.
