We are pursuing the LEED EB O&M certification of our main campus and the paper product we purchase from Office Max is FSC Chain of Custody certified. LEED considers a purchase sustainable if it consists of at least 50% FSC certified paper products. Does the FSC Chain of Custody certification for paper products require minimum % from FSC sources? How can I verify if the paper gets the LEED credit for 50% FSC certified paper products?

Thanks, Bahareh
